AgGaO2 was hydrothermally synthesized, and structural characterization showed that the crystal size of the resultant product was 40 nm. Photocatalytic findings and kinetic parameters were compared the pseudo-first-order equations of three different dyes exposed to the nanoparticles (NPs) were studied. The absorbance of similar concentrations of methylene blue (MB), methyl orange (MO) and rhodamine-B (RhB) were analyzed from 0 min to 140 min by using a UV-Vis spectrometer. Brunauer-Emmett-Teller (BET) analysis revealed that the surface area of the powder particles is 23.35 m(2)/g. The photocatalytic behavior and first-order kinetic parameters of AgGaO2 were also compared in detail.
