2D Graphene-TiO2 Composite and Its Photocatalytic Application in Water Pollutants

To solve the global water shortages and serious pollution problems, research on semiconductor photocatalysts has generated significant attention. The degradation of pollutants by titanium dioxide (TiO 2 ) exceeds other materials. However, its wide bandgap restricts photocatalytic reaction under visible light. large specific surface area good thermal conductivity graphene yielded an effective graphene-TiO catalyst combination 2D composites (2D-GTC) have shown promise, so a study preparation methods, mechanism catalytic effect different this material was undertaken. In current review, characteristics TiO their as well effects synthesis methods are introduced. 2D-GTC catalysts, in all reviewed.
