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 the continuation of the photocatalytic hydrogen (H 2 ) evolution process. Here, for the first time, the hole‐transfer dynamics from Pt‐loaded sol−gel‐prepared graphitic carbon nitride (Pt‐sg‐CN) photocatalyst were investigated using different adsorbed hole acceptors along with a sacrificial agent (ascorbic acid). A significant increment (4.84 times) in H 2  production was achieved by employing phenothiazine (PTZ) as the hole acceptor with continuous H 2  production for 3 days. A detailed charge‐transfer dynamic of the photocatalytic process in the presence of the hole acceptors was examined by time‐resolved photoluminescence and in situ electron paramagnetic resonance studies.
