Abstract A highly selective and durable electrocatalyst for carbon dioxide (CO 2 ) conversion to formate is developed, consisting of tin (Sn) nanosheets decorated with bismuth (Bi) nanoparticles. Owing the formation active sites through favorable orbital interactions at Sn‐Bi interface, Bi‐Sn bimetallic catalyst converts CO a remarkably high Faradaic efficiency (96%) production rate (0.74 mmol h −1 cm −2 −1.1 V versus reversible hydrogen electrode. Additionally, maintains its initial over an...
Electrochemical CO2 reduction (CO2RR) using renewable energy sources represents a sustainable means of producing carbon-neutral fuels. Unfortunately, low efficiency, poor product selectivity, and rapid deactivation are among the most intractable challenges CO2RR electrocatalysts. Here, we strategically propose "two ships in bottle" design for ternary Zn–Ag–O catalysts, where ZnO Ag phases twinned to constitute an individual ultrafine nanoparticle impregnated inside nanopores...
Abstract Aqueous Zn‐ion batteries are well regarded among a next‐generation energy‐storage technology due to their low cost and high safety. However, the unstable stripping/plating process leading severe dendrite growth under current density temperature impede practical application. Herein, it is demonstrated that addition of 2‐propanol can regulate outer solvation shell structure Zn 2+ by replacing water molecules establish “eutectic shell”, which provides strong affinity with (101)...
Abstract Transition metal atoms with corresponding nitrogen coordination are widely proposed as catalytic centers for the oxygen reduction reaction (ORR) in metal–nitrogen–carbon (M–N–C) catalysts. Here, an effective strategy that can tailor Fe–N–C catalysts to simultaneously enrich number of active sites while boosting their intrinsic activity and utilization is reported. This achieved by edge engineering FeN 4 via a simple ammonium chloride salt‐assisted approach, where high fraction...
CO2 electroreduction reaction offers an attractive approach to global carbon neutrality. Industrial electrolysis towards formate requires stepped-up current densities, which is limited by the difficulty of precisely reconciling competing intermediates (COOH* and HCOO*). Herein, nano-crumples induced Sn-Bi bimetallic interface-rich materials are in situ designed tailored electrodeposition under conditions, significantly expediting production. Compared with bulk alloy pure Sn, this interface...
Abstract Nanocomposite solid polymer electrolytes are considered as a promising strategy for solid‐state lithium metal batteries (SSLMBs). However, the randomly dispersed fillers in matrix with limited Li + transference number and insufficient ionic conductivity severely sacrifice ion transport capacity, thus restricting their practical application. To tackle these issues, magnetic field‐assisted alignment is proposed to disperse vertically aligned akaganéite nanotube an inorganic‐polymer...

However, majority previously reported flexible encounter problems such sluggish oxygen reaction kinetics, inferior long‐term durability, poor flexibility induced by rigid nature air cathode, all which severely hinder their practical applications....
