| 1 | Bimetallic cobalt-nickel coordination polymer electrocatalysts for enhancing oxygen evolution reaction显示文摘Coordination polymers(CPs)have great potential to be used in electrocatalysis owing to their designable compositions and structures.It is highly challenging to apply CPs as electrocatalysts for oxygen evolution reaction(OER)on account of insufficient catalytic efficiency and relatively poor stability of current electrocatalysts.Herein,through a mixed-metal strategy,one-dimensional Co_(x)Ni_(1-x)-HIPA with dual active sites was synthesized and studied for OER electrocatalysts.By changing the metal ratio of CoxNi1-x-HIPA,the OER performance was well regulated.The optimized Co_(1/2)Ni_(1/2)-HIPA exhibited minimum reaction activation energy,and represented an overpotential of 367 m V to reach 10 mA/cm^(2) at 25℃.Moreover,an overpotential of 314 m V at 10 m A/cm^(2) was obtained from Co_(1/2)Ni_(1/2)-HIPA at 55℃.This mixed-metal strategy provides a feasible way for adjusting the electronic states of the electrocatalysts to improve the electrocatalytic OER performance. | Lele Lu Qiang Li Jia Du Wei Shi Peng Cheng | 2022 | Chinese Chemical Letters2022，33，6： | 0 |
| 2 | Study on Cognition of Urban Residents on Haze Control and Their Willingness to Pay:A Case Study of Zhengzhou City and Jiaozuo City显示文摘Residents’payment is an important supplement to the government’s urban haze control costs.In this paper,Zhengzhou City and Jiaozuo City of Henan Province were taken as research objects.Through research methods such as data mining,questionnaire survey and model construction,the residents’cognition on haze control,willingness to pay and its influencing factors were deeply studied.Main research results were as below:residents in Zhengzhou and Jiaozuo have improved their awareness and satisfaction with haze control,but the growth rate was slow.In 2014,2018 and 2021,the expected values of willingness to pay for haze control in Zhengzhou were 79.94,85.52 and 47.20 yuan/month respectively,while they were 62.17,57.77 and 46.96 yuan/month in Jiaozuo City.Residents’haze awareness had the most significant effect on the willingness to pay for haze control,and there was positive correlation(P<0.05).Residents’cognition of haze control was the most important factor affecting their willingness to pay for haze control.Residents’income level and air pollution level had a positive effect on residents’willingness to pay,while residents’confidence in the government had a weak impact on their willingness to pay. | Lele DU Xiaoming CHUAI Lu LIU Yanjun HAN Hong WANG Chao FAN | 2022 | Meteorological and Environmental Research2022，13，4： | 0 |
| 3 | Strong interaction between phosphorus and wrinkle carbon sphere promote the performance of phosphorus anode material for lithium-ion batteries显示文摘The durable red phosphorus(RP)anode for lithium-ion batteries(LIBs)has attracted great attention owing to its high theoretical specific capacity(2596 mA·h·g^(-1))and moderate lithiation potential(~0.7 V vs.Li^(+)/Li).However,its intrinsic poor electrical conductivity,enormous volume expansion,and soluble intermediates(lithium polyphosphides,Li_(x)PP_(s))lead to poor cycling performance.To overcome these issues,we introduce a new type of wrinkle carbon spheres as the host for loading phosphorus through a vaporization-condensation strategy.Density functional theory calculations reveal that the wrinkle carbon sphere shows strong binding energy with P4 molecule,accelerating the adsorption and polymerization of P4,thus enhancing RP conversion in the preparation process.In the lithiation/delithiation process,the wrinkle carbon has strong bonding with phosphorus and strong adsorption with Li_(x)PP_(s),resulting in excellent cycling performance.The design strategy to modify RP polymerization via reforming the interaction between wrinkle carbon spheres and phosphorus expands the application of RP for LIBs and beyond. | Xin Li Shaojie Zhang Juan Du Lele Liu Chong Mao Jie Sun Aibing Chen | 2023 | Nano Research2023，16，7： | 0 |
| 4 | Research Progress on the Relationship between Air Pollution and Socio-economic Growth in China显示文摘Air pollution is a hot issue studied by scholars all over the world.Academic circles generally believe that socio-economic factors such as extensive economic growth,unbalanced proportion of industrial structure and unreasonable energy consumption structure are the main'culprits'of serious air pollution in China.Therefore,the relationship between air pollution and socio-economic growth has very important theoretical and practical significance for air pollution prevention and control and promoting the sustainable and healthy development of cities.Through literature research and summary methods,this paper studies the severity and harmfulness of air pollution in China,and deeply studies the research progress of socio-economic influencing factors of air pollution,environmental Kuznets curve hypothesis of air pollution,decoupling relationship between air pollution and socio-economic growth,so as to provide useful reference for the prevention and control of air pollution. | Xiaoming CHUAI Lele DU Haixia ZHOU | 2021 | Meteorological and Environmental Research2021，12，6： | 0 |
