2D/3D MoS2/TiO2 heterojunction for high-efficiency photothermal catalytic CO2 reduction by phonon heat transfer

Abstract

The 2D/3D MoS₂/TiO₂ heterojunction was prepared for photothermal catalytic CO₂ reduction. Owing to the photothermal effect enabled by the phonon heat transfer in MoS₂, the MoS₂/TiO₂ heterojunction achieved high-efficiency CO₂ reduction, with a CH₄ evolution rate of 30.42 μmol h⁻¹ g⁻¹ and a CO evolution rate of 8.25 μmol h⁻¹ g⁻¹.
