Photocatalyst sheets: from one SrTiO₃ particle to a 100 m² hydrogen farm
A survey-map graphical abstract of particulate photocatalysts for overall water splitting: an aerial view of a 100 m² array of panel reactors, with map pins leading to the aluminium-doped SrTiO₃ particle (cocatalysts for hydrogen and oxygen on different facets, 96% external quantum efficiency in the UV), the photocatalyst-sheet panel, and the polyimide membrane that recovers hydrogen safely from the mixed gas.
