Lead (Pb)-free halide perovskites have recently attracted increasing attention as potential
catalysts for CO 2 photoreduction to CO due to their potential to capture solar energy and
drive catalytic reaction. However, issues of the poor charge transfer still remain one of the
main obstacles limiting their performance due to the overwhelming radiative and
nonradiative charge-carrier recombination losses. Herein, Pb-free Sb-alloyed all-inorganic
quadruple perovskite Cs 4 Mn (Bi 1− x Sb x) 2 Cl 12 (0≤ x≤ 1) is synthesized as efficient …
