Effect of Transition Metal Dopant on the Physical and Photocatalytic properties of BiOCl

摘要

Hydrolysis method has been used to prepare Mn-BiOCl by taking different amount of MnCl_(2.4)H_2O i.e. 1%, 2% and 3%. Aggregation of particles after doping was confirmed from SEM analysis. In XRD results, the perfect incorporation of Mn ion in the crystal lattice was investigated. Band gapwas reduced from 3.6 eV to 3.3 eV by adding 1% to 3% dopant. The photocatalytic activity was evaluated by performing degradation of methylene blue dye with pure and 2% Mn-BiOCl. It was found that 72 % of the methylene bluewas degraded with pure whereas 91 % of degradation was observed with doped BiOCl within 115 min irradiation time.
