Titanium dioxide (TiO2), which was doped by Ce and Fe, was coated on multi-walled carbon nanotubes (MWCNTs) through a conventional sol-gel method. We use IR to evaluate the possible functional groups and XRD, UV and SEM to characterize the structure and surface morphology of MWCNTs. The results suggest that the TiO2, which composed of nano-scale particles, was well coated on MWCNTs via chemistry bond. The visible light photo catalytic was mentioned of its red shift in UV spectrum. And we suggest that there may be a certain mechanism between TiO2and MWCNTs during visible light processing that MWCNTs has play an important role in red shift and visible light absorption.

Cu2O/TNA/Ti photoanode showed spectral response outperformed Cu2O/Ti and Cu2O/FTO photocathodes. Cu2O/TNA/Ti showed better spectral response than that of TNA/Ti, ascribed to UV-visible light absorption of Cu2O, not to charge separation enhancement.

Light Absorption Property

A facile doping method utilizing inexpensive raw materials was proposed to achieve variation in optical bandgap and UV-visible light absorption property of MoS2 nanosheets. Carbon-assistant heating with degreasing cotton has demonstrated the development of carbon-doped MoS2 nanosheets with enhanced rich defects. The results obtained shown that modified MoS2 nanosheets with the lateral width of ~600 nm are exhibited shift of the intensively blue peaks of photo-luminescence (PL) comparing to those MoS2 nanosheets with a lateral dimension of larger than 1 μm. Optical bandgap of the carbon-doped MoS2 nanosheets was found to be broader than that of the pure MoS2 nanosheets and the prepared samples also exhibited a broadband UV-visible light absorption property.
