| 1 | Hexagonal boron nitride nanosheet for effective ambient N2 fixation to NH3显示文摘Industrial production of NH3 from N2 and H2 significantly relies on Haber-Bosch process,which suffers from high energy consume and CO2 emission.As a sustainable and environmentally-benign alternative process,electrochemical artificial N2 fixation at ambient conditions,however,is highly required efficient electrocatalysts.In this study,we demonstrate that hexagonal boron nitride nanosheet (h-BNNS) is able to electrochemically catalyze N2 to NH3.In acidic solution,h-BNNS catalyst attains a high NH3 formation rate of 22.4 μg·h-1·mg-1cat.and a high Faradic efficiency of 4.7% at-0.75 V vs.reversible hydrogen electrode,with excellent stability and durability.Density functional theory calculations reveal that unsaturated boron at the edge site can activate inert N2 molecule and significantly reduce the energy barrier for NH3 fonmation. | Ya Zhang Huitong Du Yongjun Ma Lei Ji Haoran Guo Ziqi Tian Hongyu Chen Hong Huang Guanwei Cui Abdullah M.

| 2 | Fight for carbon neutrality with state-of-the-art negative carbon emission technologies显示文摘After the Industrial Revolution,the ever-increasing atmospheric CO_(2)concentration has resulted in significant problems for human beings.Nearly all countries in the world are actively taking measures to fight for carbon neutrality.In recent years,negative carbon emission technologies have attracted much attention due to their ability to reduce or recycle excess CO_(2)in the atmosphere.This review summarizes the state-of-the-art negative carbon emission technologies,from the artificial enhancement of natural carbon sink technology to the physical,chemical,or biological methods for carbon capture,as well as CO_(2)utilization and conversion.Finally,we expound on the challenges and outlook for improving negative carbon emission technology to accelerate the pace of achieving carbon neutrality. | Jiaju Fu Pan Li Yuan Lin Huitong Du Hongzhi Liu Wenlei Zhu Hongqiang Ren | 2022 | Eco-Environment & Health2022，1，4： | 1 |
| 3 | Recent advances in carbon-supported non-precious metal singleatom catalysts for energy conversion electrocatalysis显示文摘Non-precious metal single-atom catalysts(NPM-SACs)with unique electronic structures and coordination environments have gained much attention in electrocatalysis owing to their low cost,high atomic utilization,and high performance.NPM-SACs on carbon support(NPM-SACs/CS)are promising because of the carbon substrate with a large surface area,excellent electrical conductivity,and high chemical stability.This review provides an overview of recent developments in NPM-SACs/CS for the electrocatalytic field.First,the state-of-the-art synthesis methods and advanced characterization techniques of NPM-SACs/CS are discussed in detail.Then,the structural adjustment strategy of NPM-SACs/CS for optimizing electrocatalytic performance is introduced concisely.Furthermore,we provide a comprehensive summary of recent advances in developing NPM-SACs/CS for important electrochemical reactions,including carbon dioxide reduction reaction,hydrogen evolution reaction,oxygen evolution reaction,oxygen reduction reaction,and nitrogen reduction reaction.In the end,the existing challenges and future opportunities of NPM-SACs/CS in the electrocatalytic field are highlighted. | Li-Xia Liu Yangyang Ding Linan Zhu Jin-Cheng Li Huitong Du Xiang Li Zhaoyuan Lyu Dan Du Fuqiang Liu Yuanyuan Wang Wenlei Zhu Yuehe Lin | 2023 | National Science Open2023，2，2： | 1 |
| 4 | Recent progress on rational design of catalysts for fermentative hydrogen production显示文摘The increasingly severe energy crisis has strengthened the determination to develop environmentally friendly energy.And hydrogen has emerged as a candi-date for clean energy.Among many hydrogen generation methods,biohydrogen stands out due to its environmental sustainability,simple operating environ-ment,and cost advantages.This review focuses on the rational design of catalysts for fermentative hydrogen production.The principles of microbial dark fermen-tation and photo-fermentation are elucidated exhaustively.Various strategies to increase the efficiency of fermentative hydrogen production are summa-rized,and some recent representative works from microbial dark fermentation and photo-fermentation are described.Meanwhile,perspectives and discussions on the rational design of catalysts for fermentative hydrogen production are provided. | Yifan Chai Zhaoyuan Lyu Huitong Du Pan Li Shichao Ding Yujing Jiang Hua Wang Qianhao Min Dan Du Yuehe Lin Wenlei Zhu | 2022 | SusMat2022，2，4： | 0 |
