Effects of Annealing on Photocatalytic Properties of FeWO4 Microcrystals via Solution-Based Synthesis Method
FeWO4 microcrystals were fabricated through a simple solution-based route.Then,FeWO4 samples were annealed under the circumstance of air,with the temperature of 31O ℃,and the annealing process is firstly studied for its influence on FeWO4 microcrystals.The FeWO4 microcrystals,before and after annealing treatment,were characterized by XRD,SEM,TEM,N2 adsorption-desorption,TG,IR,and UV-Vis analysis.Annealed FeWO4 samples show highly active in degradation of rhodamine B (RhB).It reveals that the adsorptive and photocatalytic properties of FeWO4 microcrystals are probably enhanced through annealing treatment.
