Fig. 5

a H2 evolution rate of Pt-HfN/Hf2ON2 catalysts with different amounts of Pt loading from aqueous methanol under visible and NIR light irradiation (λ > 400 nm). The ratio of HfN/Hf2ON2 is 1:2.1. b The performance for H2 evolution of various samples with optimal Pt loading, including HfN, Hf2ON2, and HfN/Hf2ON2 heterostructures with varying ratios of HfN to Hf2ON2, under visible and NIR light irradiation (λ > 400 nm). c The effect of different methanol concentrations on H2 evolution rates. d Typical time courses of H2 evolution amount under different illumination conditions: visible and NIR light irradiation (λ > 400 nm), AM1.5 G, and NIR light (λ > 800 nm) illumination. e Wavelength-dependent AQY of H2 evolution using the Pt-HfN/Hf2ON2 photocatalyst, along with the UV–Vis–NIR absorption spectrum of the HfN/Hf2ON2 heterostructure. Error bars represent the standard deviation from three independent measurements. Source data for the Fig. 5a–e are provided as a Source Data file.
