摘要：

The hollow spherical MoO3 photocatalyst was successfully prepared by a facile one-step spray solution combustion synthesis method (SSCS). Ammonium molybdate (AHM) and urea were used as the oxidant and fuel, respectively. The MoO3 with crystallized orthorhombic phase was detected by the X-ray diffractions. And there were many pores on MoO3 spherical shells shown in SEM results, created by the infiltration of NO2 and CO2 during the reactions. Furthermore, an illustration of the MoO3 stepwise reaction process was proposed. The MoO3 photocatalysts showed excellent photocatalytic degradation efficiencies over rhodamine B (RhB) under visible-light irradiation, and M4 sample synthesized at 600 degrees C with the urea/AHM ratio of 4 showed the highest photocatalytic degradation efficiency (82% within 60 min).
