A novel and facile biotemplating method has been presented to synthesize boron carbon nitride tubes (BCNTs) by using the low-cost kapok fibers (KFs). This pathway not only transplanted the structure of KFs into the h-BN lattice, but also introduced C simultaneously in a self-doping manner. The BCNT photocatalysts can catalyse hydrogen evolution from water under visible light illumination.

Doped Ceo2

By virtue of the systematic effects of S-doping on CeO2 and the ultrathin shell structure of CdS, the CeO2−xSx@CdS nanocomposite exhibits excellent photocatalytic activity under visible-light illumination for both H2 evolution (rate up to 1147.2 μmol g−1 h−1) and RhB degradation (efficiency reached 99.8%) as compared to CeO2, CeO2−xSx, and CdS.

In order to enhance hole/electron separation and charge transfer in photocatalysts, the heterostructured g-C3N4/CoAPO-5 hybrids materials were synthesized via a simple grinding method and were investigated using X-ray diffraction (XRD), fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). The optical properties of g-C3N4/CoAPO-5 hybrids materials were measured by ultraviolet-visible diffuse-reflectance spectroscopy (DRS), photoluminescence (PL) spectra and ultraviolet-visible absorption (UV-Vis) spectra. Under visible-light illumination, this work shows the heterogeneous g-C3N4/CoAPO-5 hybrids present a superior photocatalytic activity.

Visible light responsive CoTiO3 nanoparticles with average diameter of 100 nm were successfully synthesized by sol-gel method and were firstly applied to catalytic activation of peroxymonosulfate (PMS) for degradation of organic pollutants (Rhodamine B (RhB)). Photocatalytic experiments illustrated that CoTiO3 nanoparticles reveal good photocatalytic activity and excellent ability to activate PMS, the synergistic effect of visible light photocatalysis and sulfate radical generated from activated PMS can degradate RhB efficiently. Besides, CoTiO3 nanoparticles maintain their high photocatalytic and activation efficiency after three times recycling.
