Abstract Nanoporous metals are a class of nanostructured materials finding extensive applications in multiple fields thanks to their unique properties attributed high surface area and interconnected nanoscale ligaments. They can be prepared following different strategies, but the deposition an arbitrary pure porous metal is still challenging. Recently, dry synthesis nanoporous films based on plasma treatment thin layers deposited by physical vapour has been demonstrated, as general route...
We report the synthesis of bell-shaped Bi/Bi13S18Br2 metal/semiconductor heterostructures as a photocatalyst based on nontoxic and Earth-abundant elements. Their unique morphology arises from multistep growth process, involving (1) nucleation Bi13S18Br2 nanorods, (2) reduction metallic-Bi domain their surface induced by N,N-didodecylmethylamine, (3) heterostructure accretion localized reaction at interface promoted Ostwald ripening.

Glycerol ElectroOxidation Reaction (GEOR) is a promising alternative to the Oxygen Evolution (OER) in electrolyzers, overcoming inherent challenges of high energy demand and low‐value output water oxidation. Here, we designed non‐noble metal‐based electrocatalyst (CuO@NiBiOx, CNBO) for selective efficient GEOR. The CNBO‐catalyst demonstrated selectivity achieved nearly 100% GEOR Faradaic efficiency (FE), 80% which conveyed into formic acid (FA). Bismuth incorporation modified structure mixed...
