Fig. 3: Photocatalytic H2 production performance over the CNS-based catalysts.

a Time-dependent H2 production. b Comparative H2 production rates over different samples under visible light. The error bars represent standard deviations calculated from triplicate measurements. Reaction condition: 10 mg of the catalyst, 120 mL 10 vol% triethanolamine solution, under irradiation of a 300 W Xe lamp (λ > 400 nm).
