| 1 | Recent progress for hydrogen production by photocatalytic natural or simulated seawater splitting显示文摘Solar energy is an inexhaustible renewable energy source.Among the various methods for solar energy conversion,photocatalytic hydrogen(H2)production is considered as one of the most promising ways.Since Fujishima pioneered this field in 1972,photocatalytic water splitting to produce H2 has received widespread attention.Up to now,abundant semiconductor materials have been explored as photocatalysts for pure water splitting to produce H2.However,photocatalytic seawater splitting is more in line with the concept of sustainable development,which can greatly alleviate the problem of limited freshwater resource.At present,only few studies have focused on the process of H2 production by photocatalytic seawater splitting due to the complex composition of seawater and lack of suitable photocatalysts.In this review,we outline the most recent advances in photocatalytic seawater splitting.In particular,we introduce the H2 production photocatalysts,underlying mechanism of ions in seawater on photocatalytic seawater splitting,current challenges and future potential advances for this exciting field. | Jining Zhang Wenping Hu Shuang Cao Lingyu Piao | 2020 | Nano Research2020，13，9： | 10 |

| 4 | CARBON NANOTUBES VIA METHANE DECOMPOSITION ON AN ALUMINA SUPPORTED COBALT AEROGEL CATALYST显示文摘An alumina-supported cobalt aerogel catalyst prepared from a sol-gel and a supercritical drying method was used in the catalytic decomposition of methane. The physical-chemical properties of the catalyst were characterized and its activity for methane decomposition was investigated. The effects of calcination and reaction temperatures on the activity of the catalyst and the morphology of the carbon nanotubes produced were discussed. A CoAl2O4 spinel structure formed in the calcined catalyst. The quantity of the nanotubes produced in the reaction increases with the amount of cobalt in the reduced catalyst. A higher reaction temperature leads to a higher reaction rate, though faster deactivation of the catalyst occurs with the change. The carbon nanotubes grown on the catalyst have smooth walls and uniform di-ameter distribution. | Lingyu Piao, Jiuling Chen and Yongdan Li* Department of Catalysis Science and Technology, School of Chemical Engineering, Tianjin University, Tianjin 300072, P.

| 9 | Photocatalytic hydrogen production from seawater under full solar spectrum without sacrificial reagents using TiO_(2) nanoparticles显示文摘Photocatalytic water splitting(PWS)has attracted widespread attention as a sustainable method for converting solar to green hydrogen energy.So far PWS research has mainly focused on the development of artificial photocatalytic hydrogen production systems for pure water.It is more practically attractive to create systems for seawater,i.e.,to reduce the cost of hydrogen production and make better use of naturally occurring water resources.Herein,brookite,anatase,and rutile TiO_(2)nanoparticles are investigated as photocatalysts to explore the feasibility of such thought and have shown attractive hydrogen production performance under full solar spectrum without any sacrificial agent.It is worth noting that,brookite TiO_(2),has more suitable band gap position and excellent photoelectric properties compared with anatase and rutile TiO_(2),and has higher efficiency and stability in the process of hydrogen production.The photocatalytic hydrogen production rate of brookite TiO_(2)can reach up to 1,476μmol/g/h,the highest value reported for TiO_(2)-based systems and most other photocatalysts in seawater splitting under full spectrum.As the Cl−ions in seawater go through a cycle of oxidation and reduction,no Cl_(2) is detected in the solar hydrogen production from seawater. | Jining Zhang Yifan Lei Shuang Cao Wenping Hu Lingyu Piao Xiaobo Chen | 2022 | Nano Research2022，15，3： | 1 |
| 10 | Synergetic catalysis enhancement between H2O2 and TiO2 with single-electron-trapped oxygen vacancy显示文摘The TiO2-H2O2 system possesses excellent oxidation activity even under dark conditions.However,the mechanism of this process is unclear and inconsistent.In this work,the binary component system containing TiO2 nanoparticles(NPs)with single electron-trapped oxygen vacancy(SETOV,Vo-)and H2O2 exhibit excellent oxidative performance for tetracycline,RhB,and MO even without light irradiation.We systematically investigated the mechanism for the high activity of the TiO2-H2O2 under dark condition Reactive oxygen species(ROS)induced from H2O2 play a significant role in improving the catalytic degradation activities.X-ray photoelectron spectroscopy(XPS)and electron paramagnetic resonance(EPR)results firstly confirm that H2O2 is primarily activated by SETOVs derived from the TiO2 NPs through direct contribution of electrons,producing both.O2^-/·OOH and.OH,which are responsible for the excellent reactivity of TiO2-H2O2 system.This work not only provides a new perspective on the role of SETOVs playing in the H202 activation process,but also expands the application of TiOz in environmental conservation. | Zhijiao Wu Kai Guo Shuang Cao Wenqing Yao Lingyu Piao | 2020 | Nano Research2020，13，2： | 0 |
| 11 | Highly selective photocatalytic oxidation of methane to methyl hydroperoxide显示文摘Partial oxidation of methane into primary oxidation products with high value remains a challenge.In this work,photocatalytic oxidation of methane(CH_(4))with high methyl hydroperoxide(CH_(3)OOH)selectivity is achieved using pure titanium oxide(TiO_(2))without any cocatalyst at room temperature and atmospheric pressure.The CH_(3)OOH production rate can reach up to 2050±88μmol·g^(-1)·h^(-1) at pH≈7.0 with 100%selectivity in the liquid product.The stable reaction cycle can reach more than 30 times.This low-cost system achieves superior CH_(4) conversion activity and selectivity compared with similar work.The energy of hydrogen peroxide(H_(2)O_(2))to adsorbed hydroperoxyl radical(^(*)OOH)has a significantly lower reaction energy than conversion to adsorbed hydroxyl radical(*OH)on the(210)surface of the TiO_(2).The^(*)OOH preferentially combines with methyl radical(·CH_(3))to form the most energetically favorable CH_(3)OOH.The mild oxidative environment of this system prevents the reduction of CH_(3)OOH to CH_(3)OH or over-oxidation of CH_(4),which ensures the final CH_(3)OOH with high selectivity and stability.This work provided a low-cost but highly efficient method to achieve partial oxidation with superior selectivity,i.e.,to convert CH_(4) into high-value chemicals. | Chunling Bo Li Zhang Xiaolong Liu Huaiqiu Chang Yingxue Sun Xinyi Zhang Ting Tan Lingyu Piao | 2024 | Nano Research2024，17，4： | 0 |
| 12 | Tandem photo-oxidation of methane to methanol at room temperature and pressure over Pt/TiO_(2)显示文摘In the process of methane(CH_(4))oxidation to methanol(CH3OH),CH3OH is more easily oxidized than CH_(4),resulting in inevitable peroxide phenomenon.In this work,we innovatively proposed a tandem reaction pathway to obtain a photocatalytic oxidation process of CH_(4) with high activity and selectivity.This work confirms that the methyl hydrogen peroxide(CH3OOH),the first product of CH_(4) oxidation by H_(2)O_(2),is then completely reduced to CH3OH in an electron-rich environment.Under irradiation,H_(2)O_(2) was excited into hydroxyl radicals(·OH)and hydroperoxyl radicals(·OOH)on brookite TiO_(2) photocatalyst.The·OH oxidized CH_(4) to form methyl radicals(·CH3),which then reacted with·OOH to form CH3OOH.CH3OOH gained electrons on Pt nanoparticles(NPs)and was reduced to CH3OH.At this point,low concentration of·OH was difficult to further oxidize CH3OH,so that it can exist stably.Under the conditions of room temperature(25°C)and atmospheric pressure,the productivity of CH3OH was 883μmol/(g·h),which was 4 times more than the reported photocatalytic CH_(4) oxidation system with the same reaction conditions,and the selectivity was 100%in liquid products(98.77%for all products).The photocatalyst showed excellent stability and maintained>85%product activity after 9 catalytic cycles.This work contributed to the development of highly efficient and selective CH_(4) photooxidation system under mild conditions. | Yingxue Sun Chunling Bo Zhijie Cheng Xinyi Zhang Jianjun Liu Lingyu Piao | 2023 | Nano Research2023，16，12： | 0 |
