The electrochemical conversion of carbon dioxide (CO2) into ethanol with high added value has attracted increasing attention. Here, an efficient catalyst with abundant Cu2O/Ag interfaces for ethanol production under pulsed CO2 electrolysis is reported, which is composed of Cu2O hollow nanospheres loaded with Ag nanoparticles (named as se‐Cu2O/Ag). The CO2‐to‐ethanol Faradaic efficiency is prominently...
Electrochemical CO2 reduction reaction (CO2RR) is a promising strategy for waste CO2 utilization and intermittent electricity storage. Herein, it is reported that bimetallic Cu/Pd catalysts with enhanced *CO affinity show a promoted CO2RR performance for multi‐carbon (C2+) production under industry‐relevant high current density. Especially, bimetallic Cu/Pd‐1% catalyst shows an outstanding CO2‐to‐C2+...
Developing efficient oxygen evolution reaction (OER) electrocatalysts for seawater electrolysis is still a big challenge. Herein, a facile one‐pot approach is reported to synthesize RuO2‐incorporated NiFe‐metal organic framework (RuO2/NiFe‐MOF) with unique nanobrick‐nanosheet heterostructure as precatalyst. Driven by electric field, the RuO2/NiFe‐MOF dynamically reconstructs into RuO2 nanoparticles‐anchored...
Recycling spent lithium‐ion batteries (LIBs) is an urgent task in view of the resource shortage and environmental concerns. Here, a facile ternary molten salt approach is presented for efficiently regenerating the LiNi0.5Co0.2Mn0.3O2 (NCM523) cathode of spent LIBs. Such an approach involves the treatment of spent cathode powder in the ternary molten salt at a moderate temperature (400 °C) and subsequent...
Organic luminogens constitute promising prototypes for various optoelectronic applications. Since gaining distinct color emissions normally requires the alternation of the conjugated backbone, big issues remain in material synthetic cost and skeleton compatibility while pursuing full‐color luminescence. Upon a facile one‐step coupling, three simple but smart perchalcogenated (O, S, and Se) arenes...
Silicon holds great promise as an anode material for lithium‐ion batteries with higher energy density; its implication, however, is limited by rapid capacity fading. A catalytic growth of graphene cages on composite particles of magnesium oxide and silicon, which are made by magnesiothermic reduction reaction of silica particles, is reported herein. Catalyzed by the magnesium oxide, graphene cages...
