Abstract Harnessing solar energy to enhance the rechargeable zinc–air batteries (RZABs) performance is a promising avenue toward sustainable storage and conversion. Simultaneously enhancing light-absorption capacity carrier separation efficiency in nanomaterials, as well improving electrical conductivity configuration for electrocatalysis, presents formidable challenge due inherent trade-offs interdependencies. Here, we have developed Janus dual-atom catalyst (JDAC) with bifunctional centers efficient charge electrocatalytic through bipolar doping strategy. The situ X-ray absorption near-edge structure Raman spectroscopy analyses demonstrated that Ni Fe JDAC not only function effective sites oxygen evolution reaction reduction reaction, respectively, but also serve hole electron enrichment sites, effectively suppressing photoelectron recombination while photocurrent generation. As result, assembled JDAC-based light-assisted RZABs exhibited extraordinary stability at large current densities. This work delivers pivotal insight design catalysts efficiently convert into electric chemical energy.
