Coconut Shell Waste-Derived Porous Carbon-Supported Sn Catalysts for Efficient Electrochemical CO₂ Reduction to Formic Acid and Deuterated Formic Acid.

ABSTRACT: Industrial-level electrochemical CO₂ reduction reaction (CO₂RR) to form HCOO^- and DCOO^- requires robust Sn catalysts with high performance. In this study, the hydrothermal method was employed to load varying amounts of Sn precursors onto waste biomass-derived porous carbon to investigate the structure-activity relationship between Sn loading forms and HCOO^- selectivity. Through comprehensive ex/in situ characterizations, we discovered that with 5% Sn precursor addition, highly dispersed SnO₂ nanoparticles formed on the carbon support, enabling the catalyst to exhibit exceptional HCOO^- activity (Faradaic efficiency exceeding 90%) across a broad potential window. In situ attenuated total reflect
