Evaluation of new couple Nb2O5Sb2O3 oxide for photocatalytic degradation of orange G Dye

الملخص EN

This paper involves the study the effect of differences in calcination temperatures on the prepared couple Nb2O5/Sb2O3 oxide at percentage 1:1 with 400,500and 600 C 0 of calcination temperature and it was characterized by x-ray diffraction .

degradation test for orange G dye was carried out to determine photocatalyst activity for new couple Nb2O5/Sb2O3 oxide .

The photocatalyst experiments was performed at mass of the catalyst ( 0.05-0.3) g, pH solution in the range (2 -9) and dye concentration 10 ppm were monitored as a function of time at wavelength of 475 nm with recording optical absorbance.

The photocatalyst destruction of Orange G dye was found to follow first order kinetics.

The results indicate that 0.15 g was the best weight of the catalyst and the best pH for degradation orange G dye was at pH of solution equal to 6.8.
