MIL-125(Ti)@ZIF-67-derived MIL-125(Ti)@TiO₂ hollow nanodiscs decorated with Co₃S₄ for remarkable photocatalytic CO₂ reduction

Abstract

Fabricating photocatalysts with customizable structure and composition using different metal-organic framework (MOF) building blocks has intriguing implications in chemistry and material science, but it is challenging to do so. Here,...

Engineered CO2 conversion performance of nanostructured TiO2 photocatalysts via electrochemical hydrogenation

“…This light-driven photocatalytic CO 2 conversion not only helps to reduce the atmospheric concentration of CO 2 but also to acquire valuable fuels for energy production concurrently. 1,2 Historically, TiO 2 has intrigued researchers as a promising photocatalytic material for decades owing to its excellent material stability and favorable energy level alignment to CO 2 reduction and water oxidation since Inoue et al demonstrated TiO 2 photocatalysts for CO 2 conversion in 1979. 3 However, the 3.2 eV wide bandgap for anatase TiO 2 restricts its light absorption only to the UV region from the entire solar spectrum, and, thereby, the CO 2 conversion performance by TiO 2 photocatalysts remains at a low level.…”
