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‐C 3 N 4 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.
