Developing highly efficient electrochemical catalysts for carbon dioxide reduction reaction (CO2RR) provides a solution to battle global warming issues resulting from ever-increasing carbon footprint due to human activities.Copper (Cu) is known for its efficiency in CO2RR towards value-added hydrocarbons;hence its unique structural properties along with various Cu alloys have been extensively explored in the past decade.Here,we demonstrate a two-step approach to achieve intimate atomic Cu-Ag interfaces on the surface of Cu nanowires,which show greatly improved CO2RR selectivity towards methane (CH4).The specially designed Cu-Ag interfaces showed an impressive maximum Faradaic efficiency (FE) of 72％ towards CH4 production at-1.17 V(vs.reversible hydrogen electrode (RHE)).

The high unoccupied d band energy of Ni3N basically results in weak orbital coupling with water molecule,consequently leading to slow water dissociation kinetics.Herein,we demonstrate Cr doping can downshift the unoccupied d orbitals and strengthen the in
Developing cost-effective,efficient and bifunctional electrocatalysts is vital for both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) application.The catalytic activity of electrocatalysts could be optimized by reasonable electroni

Graphdiyne (GDY) is emerging as a promising material for various applications owing to its unique structure and fascinating properties.However,the application of GDY in electronics and optoelectronics are still in its infancy,primarily owing to the huge c
Metal-nitrogen-carbon (M-N-C) single-atom catalysts exhibit desirable electrochemical catalytic properties.However,the replacement of N atoms by heteroatoms (B,P,S,etc.) has been regarded as a useful method for regulating the coordination environment.The
共享住宿的繁荣发展吸引了大量商业经营者涌入,商业化的趋势越发显著,“共享”属性悄然变化.基于2010—2019年北京主城区Airbnb房源数据,按照商业化程度将房源划分为Ⅰ、Ⅱ、Ⅲ类.采用网格维数模型、DBSCAN聚类算法、地理探测器等方法对各类Airbnb房源的时空分布特征和空间集聚成因进行测算.结果表明:北京主城区Airbnb商业房源(Ⅱ、Ⅲ类)占比高达80％,商业化程度高于波士顿、里斯本、旧金山等境外城市;北京主城区Airbnb房源数量逐年增长,具体表现为“阶段性发展、后期稳步扩张”的特点;北京主城
Cyclic-conjugated linkages between planar-macrocyclic molecules contribute to the robustness of the two-dimensional (2D)polymerization and extension of π-interactions.The fabrication of such linkages in 2D polymers remains challenging.Combining scanning t
Developing low-energy input route for conversion of methane (CH4) to value-added methanol (CH3OH) at room temperature is important in environment and industry.Bonding in electron donor-acceptor hybrid can potentially promote charge transfer and photocatal
Potassium-ion batteries (PIBs) are appealing alternatives to conventional lithium-ion batteries (LIBs) because of their wide potential window,fast ionic conductivity in the electrolyte,and reduced cost.However,PIBs suffer from sluggish K+ reaction kinetic
Periodontitis is recognized as the major cause of tooth loss in adults,posing an adverse impact on systemic health.In periodontitis,excessive production of reactive oxygen species (ROS) at the inflamed site culminates in periodontal destruction.In this st
