Tunable Bandgap Energy and Promotion of H₂O₂ Oxidation for Overall Water Splitting from Carbon Nitride Nanowire Bundles

A stepwise four-electron reaction significantly alleviates the thermodynamics reaction barrier for overall water splitting. Regenerated 1D carbon nitride nanowire bundles from tailoring and reassembly of 2D g-C3N4 produce novel physicochemical and optoelectronic properties, which well realize the stepwise four-electron reaction along with a quantum efficiency of 5.2‰ at 420 nm.
