•Mesoporous α-GaOOH synthesis.•Surface properties tunable photocatalyst preparation.•Photocatalytic hexavalent chromium reduction.•Catalytic ozonation process for 2-EEA degradation.
The mesoporous α-GaOOH was synthesized using oxalic acid in a hydrothermal process at various hydrothermal temperatures and times. The nitrogen adsorption analysis indicated that α-GaOOH with surface areas ranging from 6 to 87 m2/g and pore sizes from 3.8 to 7.2 nm can be prepared by adjusting the experimental conditions. The photocatalytic hexavalent chromium reduction was studied under UV light irradiation and the results showed that α-GaOOH having higher surface area owned higher photocatalytic activity. The degradation of 2-ethoxy ethyl acetate in catalytic ozonation process showed that the degradation was enhanced over ozonation process in the presence of mesoporous α-GaOOH.
