Efficient degradation of organic pollutants and hydrogen evolution by g-C₃N₄ using melamine as the precursor and urea as the modifier

Abstract

A novel metal-free photocatalyst g-C₃N₄/g-C₃N₄ isotypeheterojunction has been successfully fabricated. More importantly, the as-obtained material exhibits remarkable enhanced photocatalytic properties owing to the designed visible-light bandgap and band edges..
