To enhance the solar-to-chemical conversion efficiency of CO2 photocatalysis, light active materials need to be engineered into multiscale architectures that maximize photon capture and minimize optical losses. In this paper, Lourdes, Abhinav and coauthors developed a photocatalytic foam that helps achieve this goal by coating a uniform distribution and thickness indium oxide hydroxide nanorods film onto the internal surface of an oxidized nickel foam. Optimizing the size and density of pores of the photocatalytic foam enabled optimization of photochemical and thermochemical contributions to the rate for the solar reverse water gas shift.
