Abstract The sluggish kinetics of both hydrogen evolution reaction (HER) and oxygen (OER) generate the large overpotential in water electrolysis thus high-cost production. Here, multidimensional nanoporous interpenetrating-phase FeNiZn alloy FeNi 3 intermetallic heterostructure is situ constructed on NiFe foam (FeNiZn/FeNi @NiFe) by dealloying protocol. Coupling with eminent synergism among specific constituents highly efficient mass transport from integrated porous backbone, FeNiZn/FeNi...
Li–CO2 batteries, which integrate CO2 utilization and electrochemical energy storage, offer the prospect of utilizing a greenhouse gas providing an alternative to well-established lithium-ion batteries. However, they still suffer from rather limited reversibility, low efficiency, sluggish redox reaction kinetics. To address these key issues, nanoporous Ni3Al intermetallic/Ni heterojunction (NP–Ni3Al/Ni) is purposely engineered here via alloying–etching protocol, whereby unique interactions...

Their...
Porous Mn<sub>2</sub>O<sub>3</sub> cathode shows high catalytic activity and durability for CO<sub>2</sub> electrochemical reduction evolution reactions in Li–CO<sub>2</sub> batteries.
The limited lithium-ion diffusion and depressed cathode/electrolyte interface stability greatly deteriorate the cycling rate performance of batteries, especially when they are operated at elevated temperatures (≥50 °C) and/or high charge cutoff voltages (>4.4 V vs Li/Li+). Herein, we proposed a demand-oriented surface coating strategy by introducing multifunctional LiBO2/LiAlO2 layers onto LiNi0.5Co0.2Mn0.3O2 (NCM) single crystals, in which middle LiAlO2 layer is designed to ensure intimate...
