| 6 | 稻草生物炭对铕的吸附行为及机理研究显示文摘以农业残留物为原料制备的生物炭被广泛应用于去除重金属,这对于环境保护具有双重意义。本研究以稻草为原料制备了生物炭,通过系列静态实验和光谱技术研究其对重金属铕(Eu)的吸附行为及机理。研究发现溶液pH显著影响生物炭对Eu(Ⅲ)的吸附量,但不改变吸附反应时间;腐殖酸/富里酸(HA/FA)在pH<7.0的溶液中能促进生物炭对Eu(Ⅲ)的吸附,而在pH>7.0的溶液中则抑制Eu(Ⅲ)的吸附;吸附过程主要涉及共沉淀或内表面络合机制;该吸附属于化学吸附,且吸附速率受内颗粒扩散过程的限制。此外, Freundlich模型对该吸附拟合最好, Langmuir模型显示稻草生物炭对Eu(Ⅲ)的最大吸附量为40.717 mg/kg,这可能与生物炭的层状结构和丰富的官能团有关;热力学分析表明该吸附是自发的吸热过程。这些发现有利于评估稻草生物炭在去除水中重金属方面潜在的应用价值。 | 董丽佳 吴思颖 李生波 魏作富 杨国 胡保卫 | 2020 | 无机材料学报2020，35，3： | 8 |

| 8 | 生物炭对土壤中阿特拉津吸附特征的影响显示文摘为探究生物炭对土壤中阿特拉津的吸附特征及影响因素,采用批处理实验研究了灭菌(T1)、5%秸秆生物炭+灭菌(T2)、未灭菌(T3)和5%秸秆生物炭+未灭菌(T4)条件下对土壤中阿特拉津吸附特征及土壤理化性质的影响.结果表明,在最初0—12 h内,不同处理下阿特拉津吸附量均随时间的延长而快速增加,而在12—96 h内增加较为缓慢并逐渐趋于平衡.在96 h时,T2和T4处理下阿特拉津最大吸附量分别达到46.22 mg·kg^(-1)和46.43 mg·kg^(-1),而未添加生物炭的T1和T3处理则有所降低,分别为44.20 mg·kg^(-1)和43.09 mg·kg^(-1).准二级动力学模型更好地拟合不同处理下土壤对阿特拉津吸附特征,T2和T4处理下吸附速率常数K分别为0.257 kg·mg^(-1)·h^(-1)和0.339 kg·mg^(-1)·h^(-1),显著高于未添加生物炭处理的T1和T3处理(K分别为-0.083 kg·mg^(-1)·h^(-1)和-0.261 kg·mg^(-1)·h^(-1)).内扩散模型显示添加生物炭后,土壤对阿特拉津的吸附是一个由边界扩散、内部孔隙扩散等多因素控制的复杂化学过程.添加生物炭可显著提高土壤pH、有机碳、碱解氮、速效磷和速效钾含量,其中土壤有机碳含量与阿特拉津最大吸附量之间存在显著的正相关关系(P<0.05).由此可见,添加生物炭可以提高土壤对阿特拉津的固持能力,减少其淋溶迁移风险,从而达到修复阿特拉津污染土壤的目的. | 孙涛 杨再磊 蒋靖佰伦 孙约兵 李俊芳 贾宏涛 | 2021 | 环境化学2021，40，3： | 6 |
| 9 | Environmental behavior of engineered biochars and their aging processes in soil显示文摘In recent years,due to the broad application of biochars,the preparation,environmental behavior and aging processes of biochars have attracted wide attention globally,especially the modification of biochars.However,most of the studies only consider the improvement of biochar properties right after the modification,but neglect a complete evaluation of the long-term stability and eco-toxicity of these newly developed materials after entering the environment.With the development and utilization of biochars,engineered biochars(EngBCs)will soon enter the market,but its environmental risk still remains unclear.The literature does not provide adequate information on how aging of EngBCs will affect their properties,and indirectly impact the properties of soils(cycle of elements and organic matter).Therefore,this review paper summarizes the aging process and environmental risk of biochars,aiming at better understanding the interactions between EngBCs and soil components or pollutants.More importantly,this review is to point out the contradictory speculations of environmental behavior of EngBCs studied at the present stage.Due to the modification,the EngBCs stability may be significantly reduced.However,the formation of functional group on EngBCs will enhance their interaction with soil minerals to form biochars-mineral complex,and thus EngBCs could be protected.The impacts of EngBCs after entering the environment are also ambiguous.Therefore,understanding EngBCs environmental behavior is critical,which is helpful to reduce the potential risk and to produce EngBCs following the rule of sustainable development and safety to the environment. | Wenyan Duan Patryk Oleszczuk Bo Pan Baoshan Xing | 2019 | Biochar2019，1，4： | 5 |

| 12 | Biochar characterization of invasive Pennisetum purpureum grass:effect of pyrolysis temperature显示文摘Pennisetum purpureum is one of the most invasive perennial grasses of the Poaceae family,which are abundant in south-east Asia including Brunei Darussalam.The pyrolysis process at a slow heating rate proved to be highly promising for biochar production.The production and characterization of different Pennisetum purpureum biochars have been investigated at the pyrolysis temperatures of 400℃,500℃and 600℃with a heating and nitrogen flow rate of 5℃/min and 0.5 L/min,respec-tively.The observed higher heating values were 22.18 MJ/kg,23.02 MJ/kg,23.75 MJ/kg,and the alkaline pH were 9.10,9.86,10.17 for the biochar at 400℃,500℃,600℃temperatures,respectively.The water holding capacity was one hundred percent for all biochars and continued to increase for higher pyrolysis temperature.SEM images show that the porosity of the biochars has been enhanced with increased temperatures due to the rearrangement of crystallinity and aromaticity.On the other hand,the yields of biochar have been decreased from 35.13%to 23.02%for the increase of pyrolysis temperature from 400℃to 600℃.Energy dispersive X-ray analysis shows that the O/C atomic ratios were 0.15,0.08 and 0.06 for the biochar of 400,500 and 600℃which validates the improvement in heating values.FT-IR analysis revealed that the available functional groups in the biochars were C-O,C=C,and C-H.Thermogravimetric analysis(TGA)under pyrolysis condi-tion showed residue of 46.56%,51.13%and 55.67%from the biochar at 400,500,and 600℃,respectively.The derivative thermogravimetry(DTG)graph indicates that the degradation rate is higher for 400℃biochar than the 600℃biochar. | Md Sumon Reza Shammya Afroze Muhammad S.A.Bakar Rahman Saidur Navid Aslfattahi Juntakan Taweekun Abul K.Azad | 2020 | Biochar2020，2，2： | 1 |
| 13 | 生物质衍生碳基材料在钠离子电池负极中的应用显示文摘近年来,随着可再生能源的大规模应用,开发安全可靠的储能设备对于解决可再生能源的间歇性、不稳定性等问题,实现能源的持续性输出具有重要意义。锂离子电池作为重要的储能设备已成功应用于多个领域,然而,锂资源储量有限、分布不均匀且成本较高,难以满足未来的应用需求。钠离子电池再次进入研究人员的视野,钠离子电池的储能机理与锂离子电池相似,钠与锂位于同一主族,除物理化学性质与锂相似之外,在储量和成本上同样具有较大优势。开发高容量、优异倍率性能和长循环寿命的负极材料是钠离子电池实现产业化的关键。以资源丰富、成本低廉且可再生的生物质合成的碳基负极材料得到广泛研究,其优良的储钠性能已得到证实,有望成为最具潜力的新型低成本高性能钠离子电池负极材料。本文首先介绍了生物质衍生碳基材料主要来源于植物器官、秸秆和废弃生物质,其次阐述了热解法、化学活化法和模板法等制备生物质衍生碳基负极材料的方法,探讨了不同结构的生物质衍生碳基材料的储钠性能,分析了生物质衍生碳基材料的储钠机制,并展望了生物质衍生碳基负极材料未来的研究方向。 | 苑雪 李洪基 白文慧 李正曦 杨立滨 王恺 陈哲 | 2023 | 储能科学与技术2023，12，3： | 1 |
| 14 | Sorption and degradation of imidacloprid and clothianidin in Chinese paddy soil and red soil amended with biochars显示文摘Application of biochar technology in the remediation of organic contaminated soils has drawn growing interest in recent years.In this study,sorption and degradation of two typical neonicotinoid insecticides,imidacloprid(IMI)and clothianidin(CLO)in Chinese typical paddy soil and red soil amended with six kinds of biochars were investigated.The results showed that surface area(SA),pH,total organic carbon and dissolved organic carbon(DOC)of the two soils all increased after biochar amendment,while H/C decreased.With biochar pyrolyzing temperature(PT)increasing from 300℃ to 700℃,the sorption of the two insecticides on biochar-soil mixtures increased by more than 4.3-fold,due to the increasing SA and decreasing H/C.The acidic pH of the two tested soils also favored the enhanced sorption of the insecticides by removing the ash on biochar.The amendment of low-PT(300℃)biochar promoted the biodegradation of IMI and CLO by 11.3-41.9%via providing more DOC and available N for microorganisms,while inhibiting the chemical degradation.Oppositely,the high-PT(500-700℃)biochars inhibited the biodegradation of the insecticides by decreasing their bioavailability and promoted the chemical degradation by providing mineral active groups,and generating·OH and other free radicals.In addition,soil type also affected the effects of biochar remediation.The highest 60-day degradation extent was achieved for CLO(90.5%)and IMI(81.4%)in paddy soil by adding biochar derived from pig manure at 700℃ PT.In summary,the effect of biochar on the fate of organic contaminants in soil is a comprehensive result involving several processes and a systematic study considering the type and property of biochar and soil is needed to optimize biochar technology. | Peng Zhang Lujuan Min Jingchun Tang Muhammad Khalid Rafiq Hongwen Sun | 2020 | Biochar2020，2，3： | 1 |
| 15 | Occurrence,formation and environmental fate of polycyclic aromatic hydrocarbons in biochars显示文摘Biochar application for soil and agro-environmental development has attracted great attention due to its numerous advantages:improving the soil,mitigating greenhouse gas emissions,increasing crop productivity,and augmenting soil carbon storage.However,during the pyrolytic conversion of waste biomass,polycyclic aromatic hydrocarbons(PAHs),a category of toxic organic pollutants,are inescapably generated and linger on the residual solid coproduct called biochar.Therefore,it is crucial to assess the environmental persistence,bioavailability,effects of biochar-borne PAHs on plant growth and soil microbial community dynamics,food safety,and human health after application into soils.This review highlights the basic need to unravel critical mechanisms driving PAH formation in biochar and the dynamics between the sorbent(biochar)and soil microbes,along with the possible mitigation strategies.Current research gaps,including the influence of biochar application on the short and long-term fate of PAHs,as well as the proper control measures for biochar quality and associated risks,will be discussed herein.The key research findings from this script will lead to proposals in technological and quality control measures during biochar production to ensure they are clean and safe. | Emmanuel Stephen Odinga Fredrick Owino Gudda Michael Gatheru Waigi Jian Wang Yanzheng Gao | 2021 | Fundamental Research2021，1，3： | 1 |
| 16 | Biochar produced from Amazonian agro-industrial wastes:properties and adsorbent potential of Cd^(2+) and Cu^(2+)显示文摘In the Amazon region,several residues that have been misused can serve as feedstocks for biochar production with the aim of recovering soils contaminated by heavy metals.However,these biochars need to be firstly tested for their adsorption capacity as well as their physicochemical attributes prior to field application.Therefore,this study aimed to characterize and evaluate the adsorption capacities of Cd^(2+) and Cu^(2+) of biochars produced from acai(BA),Brazil nut(BN),and palm kernel cake(BK)residues.Biochars were produced by slow pyrolysis at four different temperatures(400,500,600,and 700℃).The physicochemical properties of the biochars,such as cation exchange capacity,ash,recalcitrance index,and aromaticity were enhanced with increased pyrolysis temperature.The adsorption capacities of Cd^(2+) and Cu^(2+) showed high correlations with the physicochemical properties of biochar,indicating the importance of these characteristics in the adsorption process.Furthermore,the adsorption of Cd^(2+) and Cu^(2+) also increased with the increase in the pyrolysis temperature.In a competitive system,Cd^(2+)exhibited higher adsorption capacity than Cu^(2+) for all biochars.In general,BN showed the highest adsorption capacity,followed by BK and BA.Biochars produced from the Amazonian residues have the potential to improve soil quality when used as amendments in the recovery of soils contaminated with Cd and Cu,representing an environmentally sound technology for the reuse of these residues. | Yan Nunes Dias Edna Santos Souza Hercilia Samara Cardoso da Costa Leônidas Carrijo Azevedo Melo Evanise Silva Penido Cristine Bastos do Amarante Orivan Maria Marques Teixeira Antonio Rodrigues Fernandes | 2019 | Biochar2019，1，4： | 1 |

| 18 | Heterogeneous fenton oxidation of methylene blue with Fe-impregnated biochar catalyst显示文摘Fe-impregnated biochar(Fe-BC)as high-efficiency heterogeneous Fenton catalyst was synthesized and evaluated in detail for its catalytic activity,stability and reusability under various conditions.The optimal conditions for the Fenton oxidation of methylene blue(MB)as model dye were determined as 0.075 g/L H_(2)O_(2),0.5 g/L Fe-BC for 0.1 g/L MB,which resulted in optimum Dye:Fe_(cat):H_(2)O_(2) ratio of 1:5:0.75(on g/L basis)or[Dye]:[Fe_(total)]:[H_(2)O_(2)]molar ratio of 1:6.2:7.0 respectively.The effective degradation of MB was identified over a wider pH range,and even after four consecutive runs Fe-BC maintained above 95%MB removal rate within 3 min of treatment with low Fe release,indicating strong stability and reusability.Under the optimum Dye:Fe_(cat):H_(2)O_(2)(g/L)condition at initial pH 4,the Fe-BC achieved 99.9%removal efficiency of MB within 3 min in heterogeneous Fenton reaction(HEFR)with much less H_(2)O_(2) concentration and low catalyst dosage,demonstrat-ing its efficiency and cost-effectiveness compared to other Fenton reaction catalysts.The removal velocity of MB showed two rate steps:a fast first stage followed by a slow stage with the rate in the order of H_(2)O_(2)/Fe-BC⋙H_(2)O_(2)/biochar>biochar>H_(2)O_(2).Overall,the developed Fe-BC is more economical with strong stability and recyclability for use in HEFR for treating recalcitrant pollutants. | Jong‑Hwan Park Jim J.Wang Ki Hun Park Dong‑Cheol Seo | 2020 | Biochar2020，2，2： | 0 |

| 20 | Adsorption characteristics of ciprofloxacin onto g-MoS2 coated biochar nanocomposites显示文摘The g-MoS2 coated biochar(g-MoS2-BC)composites were synthesized by coating original biochar with g-MoS2 nanosheets at 300℃(BC300)/700℃(BC700).The adsorption properties of the g-MoS2-BC composites for ciprofloxacin(CIP)were investigated with an aim to exploit its high efficiency toward soil amendment.The specific surface area and the pore structures of biochar coated g-MoS2 nanosheets were significantly increased.The g-MoS2-BC composites provided more n electrons,which was favorable in enhancing the n-n electron donor-acceptor(EDA)interactions between CIP and biochar.As a result,the g-MoS2-BC composites showed faster adsorption rate and greater adsorption capacity for CIP than the original biochar.The coated g-MoS2 nanosheets contributed more to CIP adsorption on the g-MoS2-BC composites due to their greater CIP adsorption capacity than the original biochar.Moreover,the synergistic effect was observed for CIP adsorption on g-MoS2-BC700,and suppression effect on g-MoS2-BC300.In addition,the adsorption of CIP onto g-MoS2-BC composites also exhibited strong dependence on the solution pH,since it can affect both the adsorbent surface charge and the speciation of contaminants.It was reasonably suggested that the mechanisms of CIP adsoiption on g-MoS2-BC composites involved pore-filling effects,k-k EDA interaction,electrostatic interaction,and ion exchange interaction.These results are useful for the modification of biochar in exploiting the novel amendment for contaminated soils. | Zhenyu Yang Rong Xing Wenjun Zhou Lizhong Zhu | 2020 | Frontiers of Environmental Science & Engineering2020，14，3： | 0 |
