摘要
Bi2MoO6 hollow microspheres with cage-like pores on the outer shell were synthesized by aerosol-spraying with glucose as a template. The aerosol-spraying temperature and the amount of glucose played key roles in determining the crystal phase and the Bi2MoO6 morphology including outer shell thickness and number of cage-like pores on the outer shell. The photocatalytic degradation of rhodamine B under visible-light irradiation was examined which revealed that the reaction followed first order kinetics with respect of rhodamine B concentration and rhodamine B was completely degraded into CO2 via de-ethylation process with the formation of 5 intermediates. The as-prepared Bi2MoO6 exhibited high activity owing to the high surface area and additionally because of multiple light reflections in the hollow chamber.
