Development of γ-Al2O3 with oxygen vacancies induced by amorphous structures for photocatalytic reduction of CO2

Inducing amorphous components into Al2O3 leads to elongation of the Al-O bond and the formation of oxygen vacancies, which makes Al2O3 an independent photocatalyst for CO2 adsorption and reduction. The generation rate of CO can reach 36.5 μmol g-1 h-1, which is 6.5 times that of P25 TiO2.
