AI Technical Summary
Existing photocatalytic technologies suffer from insufficient catalyst efficiency and stability during carbon dioxide reduction, resulting in high energy costs and making it difficult to achieve efficient conversion of carbon dioxide into useful chemicals.
Photocatalysts with a core-shell structure are prepared by electrode discharge method, using a metal element or alloy as the core and a single or multiple layer of graphene as the protective catalytic layer, and controlling the polymerization direction and speed of the organic solvent to form a stable catalyst.
It achieves efficient catalytic conversion of carbon dioxide to methane at room temperature and pressure. The catalyst exhibits high efficiency and excellent stability under light conditions, making it suitable for clean energy production and environmental remediation.
