Mixed‐Phase TiO2 Nanotubes Enhance Ru Nanoparticle Activity for Hydrogen Evolution in pH‐Neutral Electrolytes

Advanced Energy and Sustainability Research, EarlyView.
Efficient water electrolysis in NaBr electrolyte is achieved using TiO2 nanotube supports decorated with Ru nanoparticles. A cooperative “job‐sharing” effect between the TiO2 proton‐storage support that provides protons to the Ru catalyst enhances hydrogen evolution, minimizes Ru demand and polarization losses, and delivers stable performance ...

Restricting Copper Reconstruction with Ultrathin Polydopamine for Selective and Stable Electrochemical CO2 Reduction Reaction to C2 Products

Advanced Energy and Sustainability Research, EarlyView.
An ultrathin polydopamine coating on copper microcubes mitigates the surface reconstruction during EC‐CO2RR. Copper nanocubes form on the surface of the microcubes in the early stages of the EC‐CO2RR, contributing to suppressed surface reconstruction and sustained Faradaic efficiency for C2 products.
