Nickel nanoparticles encapsulated in few-layer nitrogen-doped graphene (Ni@NC) are synthesized by using a Ni-based metal-organic framework as the precursor for high-temperature annealing treatment. The resulting Ni@NC materials exhibit highly efficient and ultrastable electrocatalytic activity toward hydrogen evolution reaction oxygen well overall water splitting alkaline environment.
Abstract Halide perovskite quantum dots (QDs) have great potential in photocatalytic applications if their low charge transportation efficiency and chemical instability can be overcome. To circumvent these obstacles, we anchored CsPbBr 3 QDs (CPB) on NH x ‐rich porous g‐C N 4 nanosheets (PCN) to construct the composite photocatalysts via N−Br bonding. The 20 CPB‐PCN (20 wt % of QDs) photocatalyst exhibits good stability an outstanding yield 149 μmol h −1 g acetonitrile/water for reduction CO...
Developing high‐efficiency and low‐cost photocatalysts by avoiding expensive noble metals, yet remarkably improving H 2 evolution performance, is a great challenge. Noble‐metal‐free catalysts containing Co(Fe)NC moieties have been widely reported in recent years for electrochemical oxygen reduction reaction also gained noticeable interest organic transformation. However, to date, no prior studies are available the literature about activity of N‐coordinated metal centers photocatalytic...

Water oxidation reactions driven by visible light play an important role in solar fuel production. Recently, catalysts based on earth abundant elements, such as cobalt oxides, have been studied extensively. Out of many factors, the catalyst particle size certainly affects photocatalytic activity. To reduce below 5 nm without encountering agglomeration, a practical approach is to adopt proper substrate immobilize nanoparticles. Herein, we utilized MIL-101, highly porous and robust...
