The present research project focused on the fundamental study of BiFeO3-based photocatalysis technology to pave the potential application for solar energy conversion and environmental protection areas. It was divided into several parts, including the study of fundamental theories and mechanism of charge separation dynamics for solar light photoactivity over BiFeO3 nanocomposites, design and tailor made of BiFeO3-related heterojunction nanocomposites via advanced characterization, photocatalytic performance evaluation, parametric study of catalysts, reaction intermediates detection of organics degradation and finally kinetic behavior study. Under simulated solar light irradiation, all the synthesized BiFeO3 nanocomposites exhibited much higher activities than that of commercial TiO2 in the degradation of malachite green, phenol and 2,4- dichlorophenol. The Pd-BiFeO3 had the highest photocatalytic activity among all of the samples.

1. To investigate the fundamental theories and photocatalytic mechanism of charge carriers transfer process in BFO-based heterojunction nanocomposites.
2. To design and tailor-made novel BFO-based heterojunction nanocomposites with desired characteristics and properties for efficient solar photocatalytic activity via advanced characterization.
3. To evaluate the catalytic activity of BFO-based heterojunction nanocomposites for degradation of organic pollutants.
