The interest on application of metal oxides semiconductors in photocatalysis and in photoelectrochemical devices has constantly increased. The different fields in which metal oxide-based semiconductors are applied include environmental remediation, photovoltaics, self-cleaning surfaces and hydrogen production. In the present review, the recent advances on synthesis and characterization of metal...

Sandwich structured graphene modified TiO2 mesoporous single crystals (GR-MSCs) were obtained by using the graphene embedded silica spheres as the hard template, via a hydrothermal treatment. The selective photocatalysis of TiO2 can be achieved by controlling the location of graphene in TiO2 mesoporous single crystals. The sandwich structured graphene-TiO2 composite has a photooxidation surface...

Background & objectives: Malachite green color has been extensively used in aquaculture industry around the world. The drainage of colored wastewater containing malachite green to aquatic ecosystems has created very serious risks for human health and the environment. The purpose of this study was to investigate the removal of green malachite from aqueous solutions using photocatalysis of titani...

Advanced nanomaterials with enhanced optical and photocatalytic properties for the photodegradation of organic pollutants, in particular pharmaceuticals personal care products (PPCPs), were successfully prepared by a swift one-pot synthesis. Nanostructured materials synthesized through an integrated hydrothermal procedure which generates titanate nanotubes (TNTs) different carbon dots (C-dots) ...

Semiconductor photocatalysis technology is an environmentally friendly and efficient emerging technology. This method can use sunlight as a driving force to quickly decompose organic pollutants in water bodies. Zinc oxide (ZnO) tungsten (WO3) photocatalysts absorb participate photocatalytic degradation reactions due their relatively narrow band gap. Highly photosensitive WO3 nanofibers ZnO/WO3 ...
