Transition metals-doped g-CN nanostructures as advanced photocatalysts for energy and environmental applications.

Graphitic carbon nitride (g-CN)-based heterostructured photocatalysts have received significant attention for its potential applications in the treatment of wastewater and hydrogen evolution. The utilization of semiconductor materials in heterogeneous photocatalysis has recently received great attention due to their potential and eco-friendly properties. Doping with metal ions plays a crucial role in altering the photochemical characteristics of g-CN, effectively enhancing photoabsorption into the visible range and thus improving the photocatalytic performance of doped photocatalysts.
