Carbon Nitride Nanocomposites with Layered Niobates as Photocatalysts for Hydrogen Evolution from Aqueous Solutions of Organic Acids by the Action of Visible Light
- 5 Downloads
The efficiency of H2 evolution from aqueous solutions of organic acids using composite photocatalysts derived from layered KNb3O8 and C3N4 was found to be much higher than for individual C3N4. This enhanced photocatalytic activity may be attributed to better separation of the photogenerated charges between the composite components and suppression of unwanted electron–hole recombination.
