Electrocatalysts with high activity and durability for acidic oxygen evolution reaction (OER) play a crucial role in achieving cost‐effective hydrogen production via proton exchange membrane water electrolysis. A novel electrocatalyst, Te‐doped RuO2 (Te–RuO2) nanotubes, synthesized using a template‐directed process, which significantly enhances the OER performance in acidic media is reported. The...
Bi2Te3‐based alloys are the benchmark for commercial thermoelectric (TE) materials, the widespread demand for low‐grade waste heat recovery and solid‐state refrigeration makes it imperative to enhance the figure‐of‐merits. In this study, high‐performance Bi0.5Sb1.5Te3 (BST) is realized by incorporating Cu2GeSe3 and Se. Concretely, the diffusion of Cu and Ge atoms optimizes the hole concentration and...
