Abstract A highly efficient third generation catalyst, CaCu 3 Ti 4 O 12 (CCTO) shows
excellent photoelectrochemical (PEC) and photocatalytic ability. As only 4% part of the solar
spectrum covers UV light, thus it is highly desirable to develop visible light active
photocatalyst materials like CCTO for effective solar energy conversion. A direct band
transition with a narrow band gap (1.5 eV) was observed. Under light irradiation, high
photocurrent density was found to be 0.96 mA/cm 2, indicating the visible light induced …
