Improved charge separation and transport with l-aspartic acid derived carbon-doped g-C3N4 for efficient visible-light photocatalytic H2 production

Carbon-doped graphitic carbon nitride photocatalysts were prepared through one-step calcination utilizing l -aspartic acid and urea. With the optimal CCN-8 6.6 times higher H 2 evolution rate was obtained than that of pristine CN under visible light.
