g-CN Modified with Metal Sulfides for Visible-Light-Driven Photocatalytic Degradation of Organic Pollutants.

Graphitic carbon nitride (g-CN) proved to be a promising semiconductor for the photocatalytic degradation of various organic pollutants. However, its efficacy is limited by a fast electron hole recombination, a restricted quantity of active sites, and a modest absorption in the visible range. To overcome these limitations, g-CN-BiS and g-CN-ZnS composites were effectively produced utilizing a starch-assisted technique.

Effect of Copper-Modification of g-CN on the Visible-Light-Driven Photocatalytic Oxidation of Nitrophenols.

Graphitic carbon nitride (g-CN) has proved to be a promising heterogeneous photocatalyst in the visible range. It can be used, among others, for the oxidative conversion of environmentally harmful nitrophenols occurring in wastewater. However, its photocatalytic activity needs to be enhanced, which can be achieved by modification with various dopants.
