    • Abstract:
      Hydrogen production from coal gasification provides a cleaning approach to convert coal resource into chemical energy, but the key procedures of coal gasification and thermal catalytic water-gas shift (WGS) reaction in this energy technology still suffer from high energy cost. We herein propose adopting a solar-driven WGS process instead of traditional thermal catalysis, with the aim of greatly decreasing the energy consumption. Under light irradiation, the CuO x /Al 2 O 3 delivers excellent catalytic activity (122 μmol g cat -1  s -1 of H 2 evolution and >95 % of CO conversion) which is even more efficient than noble-metal-based catalysts (Au/Al 2 O 3 and Pt/Al 2 O 3 ). Importantly, this solar-driven WGS process costs no electric/thermal power but attains 1.1 % of light-to-energy storage. The attractive performance of the solar-driven WGS reaction over CuO x /Al 2 O 3 can be attributed to the combined photothermocatalysis and photocatalysis.
