ZnO is a semiconductor material that has important physical and chemical properties, which are frequently significantly enhanced by the addition of impurities, such as doping. A study structural properties pristine functionalized (i.e., doped with Antimony Tungsten) nanoparticles been conducted for photocatalyst-based degradation methylene blue (MB) dye under both Ultraviolet (UV) solar light. ...

Abstract To solve the scientific problem of efficient removal singlet mercury from coal combustion flue gas, we propose to combine it with photocatalytic technology. We have successfully synthesized a novel material by growing iron oxide nanoparticles in situ on surface bismuth tungstate and analyzed physicochemical properties, chemical composition, morphological structure, optical properties X...

Many recent studies have been reported on the photodegradation of the organic compounds in industrial wastewater in the presence of TiO2 semiconductor as photocatalyst. Heterogeneous photocatalysts using Iron as a dopant metal, so far, have been reported for various environmental applications. This paper highlights the recent advances and applications of Fe-TiO2 photocatalysis for the degradati...

The last decade has seen significant progresses in the application of combinatorial approaches and high-throughput screening in photocatalyst discovery.

nanoparticles of zinc sulfide as undoped and doped with copper were used as photocatalyst in the photodegradation of hmx (octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine) and rdx (hexahydro-1,3,5-trinitro-1,3,5-triazine) as nitramine explosives under uv and vis irradiations. photoreactivity of doped zinc sulfide was varied with dopant, mole fraction of dopant to zinc ion, ph of solution, dosag...

A practical photocatalyst should be able to integrate together various functions including the extended solar conversion, a feasible and economic recyclability, and above the room temperature operation potential, et al., in order to fulfill the spreading application needs in nowadays. In this report, a multifunctional single-phase photocatalyst which possesses a high photoactivity extended into...

The photocatalytic inactivation (PCI) of Escherichia coli (Gram-negative) and Bacillus subtilis (Gram-positive) was performed using polyoxometalate (POM) as a homogeneous photocatalyst and compared with that of heterogeneous TiO2 photocatalyst. Aqueous suspensions of the microorganisms (10(7)-10(8)cfu ml(-1)) and POM (or TiO2) were irradiated with black light lamps. The POM-PCI was faster than ...

Organic and inorganic compounds utilised at different stages of various industrial processes are lost into effluent water and eventually find their way into fresh water sources where they cause devastating effects on the ecosystem due to their stability, toxicity, and non-biodegradable nature. Semiconductor photocatalysis has been highlighted as a promising technology for the treatment of water...
