In the present study, comparison of  photocatalytic activity of nanostructures semiconductor zinc oxide (ZnO) was prepared using the different methods on the degradation of organic dye such as methylene blue that was investigated. Previous studies have proved that such semiconductors can degrade most kinds of persistent organic pollutants, such as detergents, dyes, pesticides and volatile organ...

Overall water splitting was achieved on a simple perovskite oxynitride photocatalyst, CaTaO2N, with an absorption edge at 510 nm. This photocatalyst, modified with a Rh-Cr bimetallic oxide cocatalyst, produced stoichiometric H2 and O2 steadily under UV and visible light irradiation after coating of the photocatalyst particles with amorphous Ti oxyhydroxide.

Abstract Nickel oxide (NiO) is one of the very few p -type semiconducting oxides, study which gaining increasing attention in recent years due to its potential applicability many emerging fields technological research. Actually, a growing number scientific works focus on NiO-based electrochromic devices, high-frequency spintronics, fuel cell electrodes, supercapacitors, photocatalyst, chemical/...

This study examined the antimicrobial/antifungal ability of a tissue conditioner containing a photocatalyst for Escherichia coli, Streptococcus mutans, Staphylococcus aureus and Candida albicans. The photocatalyst was mixed with tissue conditioners powders at concentrations of 0, 10, 15, and 20 wt%. Tissue conditioners powders containing a photocatalyst were mixed with liquid to make test speci...

CeO2/ZnO nanocomposites were synthesized by microwave method that is the fast process. One of an eco-friendly solvent, ethylene glycol were used the effect of time and power of irradiation were investigated on morphology and size of nanoparticle. Prepared CeO2/ZnO nanocomposites are characterized with X-ray diffraction (XRD) analysis, Transmission Electron Microscopy (TEM), Fourier Transform In...

A new heterogeneous photocatalyst was prepared by incorporation of methylene blue into ZSM-5 zeolite. This photocatalyst effectively absorbs light in visible range of the spectrum and when irradiated with visible light, it generates reactive oxygen species (ROS) in aqueous environment. Efficiency of the photocatalyst was tested on dechlorination of a model compound 4-chlorophenol and on growth ...

An "infinite recycling" method for enhancing the durable applications of a ZnS nano-photocatalyst is shown. Based on the finding of thermodynamic stable nanophase of ZnS, we designed a strategy in which the deactivated ZnS nano-photocatalyst could be recovered into its original state. This ZnS photocatalyst can be used repeatedly without being released into environment as nano-waste. The strate...

Pt nanoparticles with tunable size are prepared on the entire surface of facet-engineered Cu2WS4 decahedral photocatalyst via a kinetic-controlled chemical reduction process. The {101} facets of the photocatalyst which featured photo-oxidation, are successfully activated for photoreduction by Pt. The resulting photocatalyst shows an activity nine times higher compared to that of the only {001}-...

Hierarchical heterostructures of beta-iron oxyhydroxide (β-FeOOH) nanostructures on electrospun TiO2 nanofibers were synthesized by a facile hydrothermal method. This synthesis method proves to be versatile to tailoring of β-FeOOH structural design that cuts across zero-dimensional particles (TF-P), one-dimensional needles (TF-N) to two-dimensional flakes (TF-F). In addition, synthesizing such ...
