Simple Synthesis and Activities of Visible-Light Activities BiVO4 Doped Al via Solid State Method

Using the Bi (NO3)3•5H2O and NH4VO3 as raw materials, Al(NO3)3•9H2O provides Al3+ doping, BiVO4 photocatalysts with different Al3+ doping amount were successfully prepared by a low-temperature solid state grinding method. And it was characterized by XRD. The Methyl Orange (MO) was simulated as the degradation material under the visible light, which was used to study the influence of the amount of photocatalyst and the illumination time. The results showed that the catalytic effect of Al/BiVO4 photocatalysts was enhanced by comparing with pure BiVO4, but enhanced a little. And the possible causes of enhanced photocatalytic activity via doping have been discussed.
