Fig. 6: Photocatalytic hydrogen production using reaction product mixture.

a Illustration of photocatalytic hydrogen production mechanism using the reaction product mixture after hydrothermal degradation of UHMWPE MPs and the band structure of FeSA-hCN, determined based on Supplementary Fig. 53. b Photocatalytic hydrogen production performance using reaction product mixture under different reaction conditions under simulated AM1.5 G solar illumination (100 mW cm-2) c Long-term photocatalytic hydrogen production test. d Online isotope ratio MS spectra. e, MS spectra of gas products using H2O as the reactant. f MS spectra of gas products using D2O as the reactant.
