Photocatalysis is known as a new and cost-effective method to solve the problems of energy shortage environmental pollution. Although application this seems practical, finding an efficient stable photocatalyst with suitable bandgap visible-light sensitivity remains challenging. In context, vanadate compounds photocatalysts have been synthesized used emerging composites, their efficiency has imp...

Some tungsten catalysts of interest that are synthesized bismuth tungstate (BT) and Tetrabutylammonium decatungstate (TBADT), using two consolidated procedures. BT is used as a photo-catalyst for the simulated solar light degradation ofloxacin (OFL) antibiotic under relevant real conditions (µg L−1, fresh water) with limit 0.05 g L−1 catalyst. A quantitative drug decomposition occurred followin...

Au photosensitization can endow TiO2 visible-light-driven photocatalytic properties. Herein, via facet-optimized brookite TiO2 with tunable electronic band structures as the substrate, we found that intense visible light excitation of Au will result in the accumulation of hot-electrons, which will negatively shift the EF of Au and lower the Schottky barrier, thus ensuring their consecutive inje...

The direct hydroamination of alkynes driven by visible light can be achieved in high yield and selectivity at ambient temperature using supported gold nanoparticles (AuNPs) as photocatalysts. Aniline molecules interact with visible light activated AuNPs meanwhile alkynes could be activated at active sites on the support. The findings reveal a new green approach for synthesis of fine organic com...

Based on first principles calculations, we predict semihydrogenated graphitic BN (sh-BN) sheet is a potential metal-free visible-light driven photocatalyst for water splitting. The ground state of sh-BN is a strip-like antiferromagnetic semiconductor with a band gap suitable for visible-light absorption. The redox potentials of water splitting are all located inside the band gap and the probabi...
