Multiscale regulation of S, N, O tri-doped carbon/Co8FeS8 catalysts with SO42−-riched and lattice distortion for efficient water splitting

The multiscale regulation of heteroatom configuration, lattice defects and SO 4 2− was realized by deep eutectic solvent system. The catalytic performance of the catalyst with multi-scale regulation is significantly improved. The regulation mechanism of C and SO 4 2− on metal sites was revealed.
