Ultrathin tin monosulfide nanosheets with the exposed (001) plane for efficient electrocatalytic conversion of CO₂ into formate.

ABSTRACT: Current Sn-based materials are ideal catalysts developed to drive the electrochemical conversion of CO₂ to formate, but competing proton reduction to hydrogen is an ever-present drain on catalytic selectivity. Herein, we report a reliable electrochemical exfoliation route, with the assistance of alternating voltage, for large-scale preparation of two-dimensional (2D) ultrathin tin monosulfide nanosheets (SnS NSs), which feature a large lateral size of 1.0 μm with a thickness of ∼5.0 nm. Systematic electrochemical studies demonstrated that the achieved SnS NSs exhibited an outstanding electrocatalytic activity towards the CO₂ reduction reaction (CO₂RR) to the formate product, as evidenced by a considerable faradaic efficiency (F.E.) of 82.1%, a high partial
