Facile Synthesis of S-scheme α-Fe2O3/BiOBr/MoS2 Nano heterojunction with enhanced visible-light-induced photocatalytic activity for efficient Hydrogen production.

Abstract

A novel 2D-2D S-Scheme α-Fe2O3 / BiOBr / MoS2 heterojunction to act as photocatalyst for effective visible-light using photocatalytic applications is synthesized and characterized in this research. We used hydrothermal method to prepare our heterojunction ternary composite. The characterization used to check our composite were XRD, XPS, EDS, SEM, TEM, and HRTEM. Through DRS and PL, the material's optical characteristics were verified. The 2D-2D S-Scheme α-Fe2O3/BiOBr/MoS2 ternary composite was applied for the development of photocatalytic hydrogen and the results showed excellent hydrogen production up to 57 mmolh-1 g-1. This ternary catalyst performed better than α-Fe2O3 and BiOBr by themselves.
