Large-Scale Synthesis of Multifunctional Single-Phase Co₂ C Nanomaterials.

ABSTRACT: Achieving scalable synthesis of nanoscale transition-metal carbides (TMCs), regarded as substitutes for platinum-group noble metals, remains an ongoing challenge. Herein, a 100-g scale synthesis of single-phased cobalt carbide (Co₂ C) through carburization of Co-based Prussian Blue Analog (Co-PBA) is reported in CO₂ /H₂ atmosphere under mild conditions (230 °C, ambient pressure). Textural property investigations indicate a successful preparation of orthorhombic-phased Co₂ C nanomaterials with Pt-group-like electronic properties. As a demonstration, Co₂ C achieves landmark photo-assisted thermal catalytic CO₂ conversion rates with photo-switched product selectivity, which far exceeds the representative Pt-group-metal-based ca
