Continuous Charge Transport in Carbon Nitride Modulated by Interfacial Chemical Bond and Homophase Junction to Boost Photocatalytic Hydrogen Production.

Efficient separation of photogenerated electrons and holes is of key importance in photocatalysis. Tuning the charge separation pathway is significant but still suffering from low efficiency for the charge extraction from semiconductors. Herein, taking 2D g-C N (CN) nanosheets as a model photocatalyst, it was found the decoration of homophase junction between brookite TiO rods and nanoparticles (B -B ) onto CN can effectively modulate photogenerated charge extraction and transfer in B -B /CN composites.
