Interface coassembly of mesoporous MoS₂based-frameworks for enhanced near-infrared light driven photocatalysis

Abstract

The three-dimensional porous Fe3O4@Cu2-xS-MoS2 framework is reported for the first time. The as-prepared 3D framework exhibits good structural stability, high surface area, enhanced adsorption capacity to substrates, and strong absorption in the NIR range. As a result, such hybrid frameworks exhibit excellent NIR-light photocatalytic activity and stable cycling for the direct arylation of heteroaromatics at room temperature.

Sunlight induced photo-thermal synergistic catalytic CO2 conversion via localized surface plasmon resonance of MoO3−x

“…Recently, photo-thermal synergistic catalysis combining thermochemical and photochemical conversion appeared as a promising method for improving the efficiency. [9,10] Sunlight can be divided into three parts: ultraviolet (UV) light (λ < 400 nm), visible (Vis) light (400 nm < λ < 800 nm) and infrared (IR) light (λ > 800 nm). UV-Vis and IR light can induce photocatalytic and thermocatalytic reactions, respectively.…”
