The photocatalytic CO2 reduction over LaPO4 was significantly enhanced by simply introducing CoCl2 into the aqueous medium. The introduced CoCl2 functioned as a co-catalyst accelerating photogenerated hole transfer, by the reversible redox couple CoIII–Cl/CoII–Cl, effectively suppressing the recombination of photogenerated charges.
