Strained few-layer MoS₂ with atomic copper and selectively exposed in-plane sulfur vacancies for CO₂ hydrogenation to methanol.

ABSTRACT: In-plane sulfur vacancies (Sv) in molybdenum disulfide (MoS₂) were newly unveiled for CO₂ hydrogenation to methanol, whereas edge Sv were found to facilitate methane formation. Thus, selective exposure and activation of basal plane is crucial for methanol synthesis. Here, we report a mesoporous silica-encapsulated MoS₂ catalysts with fullerene-like structure and atomic copper (Cu/MoS₂@SiO₂). The main approach is based on a physically constrained topologic conversion of molybdenum dioxide (MoO₂) to MoS₂ within silica. The spherical curvature enables the generation of strain and Sv in inert basal plane. More importantly, fullerene-like structure of few-layer MoS₂ can selectively expose in-plane Sv and red
