A BiOBr/reduced graphene oxide (RGO) composite aerogel with BiOBr nanoplates grown on an interconnected three-dimensional RGO-based porous network was prepared by one-pot hydrothermal method using l-lysine as a reducing agent and the cross-linker. Its enhanced adsorption toward pollutants owing to its large Brunauer–Emmett–Teller specific surface area and spongy nature, improved light absorption due to its extremely lightweight nature and the RGO promoting photogenerated charge separation contributed to the BiOBr/RGO aerogel’s enhanced activity for photocatalytic degradation in an aqueous system. The BiOBr/RGO aerogel also showed high stability and can be easily separated from the reaction systems for recycling. The facile one-pot method has been proved to be generic in the formations of different semiconductor embedded RGO aerogels like BiOX/RGO (X = Cl and I), CdS/RGO and Fe2O3/RGO aerogels, which combine the advantages of enhanced photocatalytic activity with facile recycling for applications in aqueous photocatalytic reaction systems.

A green, sustainable and cost-effective strategy for the synthesis of thiolated products.

Rational design and controllable synthesis of multiple metal components according to chemical composition and morphology are essential for obtaining desirable electrochemical performance for efficient hydrogen production because of the morphology and synergistic effects of different components. Herein, we report an approach to facilely fabricate bimetal compounds with a well-defined hollow nanoprism structure using a self-templated strategy to synthesize novel hierarchical NiCo-layered double hydroxide (NiCo-LDH) nanosheets as precursors followed by in situ phosphorization. Among the as-synthesized products of different mole ratios of Ni/Co, the NiCo 2 −B−P nanoprisms that integrate the advantages of a hollow structure, an optimal Ni−Co synergistic effect, and a unique Bdoped CoP/Ni 2 P bimetallic phosphide derived from NiCo-LDH nanosheets exhibit excellent hydrogen evolution reaction (HER) activity in an alkaline solution at 10 mA cm −2 with the lowest overpotential of 78 mV and long-term stability. This study may offer an appropriate structure and compositional design of bimetallic alkaline HER catalysts.
