Promoting Photocatalytic Hydrogen Evolution Activity of Graphitic Carbon Nitride with Hole‐Transfer Agents

Visible light‐driven photocatalytic reduction of protons to H 2 is considered a promising way of solar‐to‐chemical energy conversion. Effective transfer of the photogenerated electrons and holes to the surface of the photocatalyst by minimizing their recombination is essential for achieving a high photocatalytic activity. In general, a sacrificial electron donor is used as a hole scavenger to remove photogenerated holes from the valence band for...
