Illustration of synthetic strategy. a) An un-patterned layer of Mo:BiVO4 with thickness of 150 nm is deposited on FTO-coated glass. b) A colloidal crystal template is formed on the top surface by evaporation-induced self-assembly. c) The precursor is infiltrated, and the template removed to form an inverse opal structure. d) Surface plasmon effects are introduced by infiltrating Au NPs into the io-Mo:BiVO4.
