Abstract: Metal ion cocatalysts have huge prospect for photocatalytic CO 2 reduction coupled with organic decomposition because of their cost effectiveness and abundant active sites. Herein, we exploit a defect−group oriented tactic to induce dual−structured Co sites on BiOCl with rich surface hydroxyls (OHs) and oxygen vacancies (OVs) (labeled as BiO 1− x Cl−OH), in which the surface OHs and OVs acted as anchoring points to anchor Co2+ ions. Density functional theory calculations manifested that surface OHs anchored Co2+ ions via hydrogen bonding to produce tight OH−Co sites, meanwhile, surface OVs with unsaturated metal sites and unpaired electrons captured Co2+ ions through chemical bonding to form close−knit OV−Co site. The as−generated OV−Co and OH−Co site served as reductive and oxidative cocatalyst for CO 2 reduction and tetracycline oxidation, respectively, thereby achieving high−efficiency redox activity. This work provided a novel strategy to devise progressive dual functional metal ions cocatalysts for high−efficiency CO 2 reduction and organic pollutants oxidation. [Display omitted] • Dual−structured Co sites on BiOCl with rich surface OHs and OVs was designed. • The as−generated OV−Co site acted as reductive cocatalyst for CO 2 reduction. • The OH−Co site served as oxidative cocatalyst for organic pollutant oxidation. • Coupled reaction system actualized the full utilization of the charges.
