Abstract: The iridium-incorporated Co3O4 (Ir-Co3O4) catalyst is obtained from binary CoIr-based metal-organic framework precursors via controlled calcination treatment. Structural characterization reveals that in situ incorporation of Ir cations can cause lattice expansion of Co3O4 and regulate… read more here.

DOI: 10.1103/physrevlett.128.136401
Abstract: It has been experimentally observed that light-induced lattice expansion could enhance the solar conversion efficiency in hybrid perovskites, but the origin remains elusive. By performing rigorous first-principles calculations for a prototypical hybrid-perovskite FAPbI_{3} (FA: formamidinium),… read more here.
