Precise construction of heteronuclear dual-atom catalysts using irradiation

A strategy for the precise and scalable synthesis of a series of M1M2 (where M is a metal ion) heteronuclear dual-atom catalysts (DACs) is proposed. Photoinduced electron accumulation at the M1 sites results in the capture and reduction of M2 cations close to the M1 sites to generate DACs with high purity.
