Constructing step-scheme (S-scheme) heterojunctions has been confirmed as a promising strategy for enhancing the photocatalytic activity of composite materials. In this work, series sulfur-doped g-C3N4 (SCN)/TiO2 S-scheme photocatalysts were synthesized using electrospinning and calcination methods. The as-prepared SCN/TiO2 composites showed superior performance than pure TiO2 SCN in degradatio...

ConspectusSemiconductor photocatalysis, usually referred to simply as “photocatalysis” is a relatively new and yet still growing subject area, which has led billion-dollar industry, mostly focused on the production of self-cleaning architectural materials, such glass, paint, tiles, fabric, plastic concrete. All materials need be tested for activity, but activity there are few appropriate tests;...

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. This paper aims at providing a comprehensive review on the parallel synthesis and high-throughput characterization of photocatalysts, including the development of instrumentation, strategy of experiment, preparation of libraries, high-throughpu...

In recent years, graphitic carbon nitride (g-C3N4) has received substantial interest as a photocatalyst for metal-free, visiblelight promoted reactions. It exhibits a graphite-like, layered structure wherein tris-triazine units are connected through C–N-bonds forming a two-dimensional layer. g-C3N4 can be synthesized via various methods such as pyrolysis of urea or other nitrogen-rich precursor...

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...
