Photocatalytic H2 generation using aqueous ZnSe NRs. A) Ligand‐free ZnSe NRs in the presence of different co‐catalysts (3 h irradiation). B) Effect of the NR capping ligand. C) ZnSe‐BF4 under different irradiation spectra (1 h irradiation). D) Long‐term activity of ZnSe‐BF4 with the photoreactor being purged with N2 after 20 h. The cumulative amount of H2 is shown. Conditions unless stated otherwise: 50 mg L−1 ZnSe NRs, 0.4 m AA, pH 4.5, 20 μm Ni(BF4)2, 25 °C, 100 mW cm−2, AM 1.5G, λ>400 nm.
