Single-Atom Platinum Catalyst for Efficient CO₂ Conversion via Reverse Water Gas Shift Reaction.

ABSTRACT: The need to tackle CO₂ emissions arising from the continuously rising combustion of fossil fuels has sparked considerable interest in investigating the reverse water gas shift (RWGS) reaction. This reaction holds great promise as an alternative technique for the conversion and utilization of CO₂. In this study, a scalable method was employed to synthesize a single-atom Pt catalyst, uniformly dispersed on SiC, where up to 6.4 wt% Pt₁ was loaded onto a support based on ligand modification and UV photoreduction. This Pt₁/SiC catalyst exhibited a high selectivity (100%) towards the RWGS reaction; 54% CO₂ conversion was observed at 900 °C with a H₂/CO₂ feed-in ratio of 1:1, significantly higher than the conventional Pt
