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

Abstract in brief

• The study describes a scalable method to synthesize single-phase cobalt carbide (Co₃C) nanomaterials in large quantities (100g scale) through a mild carburization process, resulting in orthorhombic-phase Co₃C with Pt-group-like electronic properties.
• These Co₃C nanomaterials demonstrate exceptional catalytic performance in photoassisted thermal CO conversion, achieving higher rates and selectivity than traditional platinum-group catalysts due to their superior light absorption and photothermal abilities.
• Beyond catalysis, Co₃C exhibits diverse potential applications, including antibacterial therapy, water evaporation, electrochemical hydrogen evolution, and batteries, highlighting its multifunctional nature and promising future in various technological fields.]
