| 1 | Fenton-like degradation of Methylene Blue using paper mill sludge-derived magnetically separable heterogeneous catalyst:Characterization and mechanism显示文摘For the paper industry, the disposal and management of the yielded sludge are a considerable challenge. In our work, the paper mill sludge-derived magnetically separable heterogeneous catalyst(PMS-Fe-380) was prepared easily through a facile synthesis method. The morphology and structure of PMS-Fe-380 were fully characterized by means of X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, and Brunauer–Emmet–Teller analysis. The catalytic activity of PMS-Fe-380 was evaluated by degradation of Methylene Blue(MB). The reusability and stability of PMS-Fe-380 were evaluated in five repeated runs, which suggested that PMS-Fe-380 manifested excellent stability of catalytic activity. Moreover,leaching tests indicated that the leached iron is negligible(<0.5 mg/L). This study provides an alternative environmentally friendly reuse method for paper mill sludge and a novel catalyst PMS-Fe-380 that can be considered as a promising heterogeneous Fenton-like catalyst. | Guoqiang Zhou Ziwen Chen Fei Fang Yuefeng He Haili Sun Huixiang Shi | 2015 | Journal of Environmental Sciences2015，27，9： | 6 |
| 2 | Upcycling of phosphogypsum waste for efficient zinc-ion batteries显示文摘Zinc metal is a promising anode material for next-generation aqueous batteries,but its practical application is limited by the formation of zinc dendrite.To prevent zinc dendrite growth,various Zn^(2+)-conducting but water-isolating solid-electrolyte interphase(SEI)films have been developed,however,the required high-purity chemical materials are extremely expensive.In this work,phosphogypsum(PG),an industrial byproduct produced from the phosphoric acid industry,is employed as a multifunctional protective layer to navigate uniform zinc deposition.Theoretical and experimental results demonstrate that PG-derived CaSO_(4)2H_(2)O can act as an artificial SEI layer to provide fast channels for Zn^(2+)transport.Moreover,CaSO_(4)2H_(2)O could release calcium ions(Ca^(2+))due to its relatively high Kspvalue,which have a higher binding energy than that of Zn^(2+)on the Zn surface,thus preferentially adsorbing to the tips of the protuberances to force zinc ions to nucleate at inert region.As a result,the Zn@PG anode achieves a high Coulombic efficiency of 99.5%during 500 cycles and long-time stability over 1000 hours at 1 m A cm^(-2).Our findings will not only construct a low-cost artificial SEI film for practical metal batteries,but also achieve a high-value utilization of phosphogypsum waste. | Huanwen Wang Can Luo Yinyin Qian Caihong Yang Xiaojun Shi Yansheng Gong Rui Wang Beibei He Jun Jin Aidong Tang Edison Huixiang Ang Huaming Yang | 2023 | Journal of Energy Chemistry2023，，6： | 1 |
| 3 | Photodegradation of Orange Ⅱ using waste paper sludge-derived heterogeneous catalyst in the presence of oxalate under ultraviolet light emitting diode irradiation显示文摘A waste paper sludge-derived heterogeneous catalyst(WPS-Fe-350) was synthesized via a facile method and successfully applied for the degradation of Orange Ⅱ in the presence of oxalic acid under the illumination of ultraviolet light emitting diode(UV-LED) Powder X-ray diffraction,Fourier-transform infrared spectroscopy,scanning electronic microscopy and N2 sorption isotherm analysis indicated the formation of α-Fe2O3 in the mesoporous nanocomposite.The degradation test showed that WPS-Fe-350 exhibited rapid Orange Ⅱ(OⅡ) degradation and mineralization in the presence of oxalic acid under the illumination of UV-LED.The effects of p H,oxalic acid concentration and dosage of the catalyst on the degradation of OⅡ were evaluated,respectively.Under the optimal conditions(1 g/L catalyst dosage,2 mmol/L oxalic acid and p H 3.0),the degradation percentage for a solution containing 30 mg/L OⅡ reached 83.4% under illumination by UV-LED for 80 min.Moreover,five cyclic tests for OⅡ degradation suggested that WPS-Fe-350 exhibited excellent stability of catalytic activity.Hence,this study provides an alternative environmentally friendly way to reuse waste paper sludge and an effective and economically viable method for degradation of azo dyes and other refractory organic pollutants in water. | Guoqiang Zhou Jinyi Guo Guowang Zhou Xiankai Wan Huixiang Shi | 2016 | Journal of Environmental Sciences2016，28，9： | 1 |

| 5 | Gut microbiota and differential genes-maintained homeostasis is key to maintaining health of individuals with Yang-deficiency constitution显示文摘OBJECTIVE:Yang-deficiency constitution(YADC)is a common unbalanced constitution that predisposes individuals to certain diseases.However,not all people with YADC manifest develop diseases.This calls for delineation of the underlying molecular mechanisms.Previous studies suggested that the gut microbiota and gene differential expression should be considered.METHODS:In the present study,we compared profiles of gut microbiota between four healthy YADC individuals and those of five healthy balanced constitution(BC)counterparts,based on 16 S r RNA gene sequence analysis.Furthermore,YADC relevant genes identified by comparing 62 healthy YADC and 58 healthy BC individuals in total to perform intersection analysis,functional clustering and pathway enrichment analyses.RESULTS:The levels of harmful gut microbiota(Prevotellaceae,LDA score>4.0,P=0.0141)and beneficial gut microbiota(Ruminococcaceae,LDA score>4.0,P=0.0025,Faecalibacterium,LDA score>4.0,P=0.0484)were both elevated in healthy YADC individuals.Also,we found that the specific metabolic pathway with 2,6-Dichloro-p-hydroquinone 1,2-Dioxygenase(Pcp A)as the core in gut microbiota and the glutathione transferase activity has been enriched by YADC relevant genes in healthy YADC individuals were both responsible for the detoxification of halogenated aromatic hydrocarbon substances.CONCLUSIONS:Both beneficial and harmful factors had been detected in healthy YADC individuals,functionally,they may have triggered homeostasis to maintain the health of individuals with YADC.The homeostasis may be maintained by beneficial and harmful factors from gut flora and genes.Future studies are expected to focus on halogenated aromatic hydrocarbons and their detoxification processes. | ZHANG Huixiang WANG Limei GUO Jipeng WANG Jiai ZHANG Qianqian WANG Yutao LIU Xun ZHANG Lihuan SHI Lanlan WU Hongxiang CAO Xue | 2022 | Journal of Traditional Chinese Medicine2022，42，1： | 0 |
