Tungsten Oxide

Four chlorophenol is a major component of biological pesticides, wood preservatives, dyes and rust removing agents. Four chlorophenol is also used in Asia, Africa and South America to prevent and control schistosomiasis; In addition, biological treatment of municipal wastewater and industrial waste water also contains chlorophenols. Four chlorophenol wastewater is a kind of three toxic agent, which is carcinogenic, teratogenic and mutagenic. It is easy to cause serious pollution to the environment and is difficult to decompose, therefore, the United States Environmental Protection Agency (EPA) has included it in the list of 129 priority environmental control pollutants. In recent years, the application of semiconductor photocatalysis technology in environmental management has received extensive attention, among them, the tungstate semiconductor photocatalyst, with its non-toxic and high photocatalytic activity, has gradually replaced the early physical and chemical treatment m...

China is a major producer of antibiotics and one of the most serious countries that abuse antibiotics. Livestock farming is the hardest hit by the use of antibiotics, with the rapid development of aquaculture, the residues of antibiotics in water, sediment and soil become more and more serious. Tetracycline is the most common antibiotic used in livestock farming. Its main characteristics are broad-spectrum antibacterial and cheap, unlike other organic wastewater contamination, tetracycline and other antibiotic compounds usually have a shorter degradation half-life in the environment, however, the use of tetracyclines in livestock and aquaculture has never ceased to allow them to enter the environment, manifested as "persistent". Such a consequence is that antibiotics selectively inhibit some environmental microorganisms in the environment and induce the emergence of some antibiotic resistance groups, thus triggering a particular ecotoxicological effect, this is why s...

A WO 3 –graphene photocatalyst has been developed that can degrade the dye Rhodamine B almost completely in 15 minutes. This is much faster than the degradation times that can be achieved by bare WO 3  or TiO 2 . The catalyst consists of a porous tungsten oxide  framework with a graphene film and is directly produced via electrospinning. The authors from China and the USA envision that this potent electrocatalyst can be used in environmental applications for the photocatalytic degradation of dye pollutants under visible light. The superior properties of the photocatalyst can be explained by its components and structure. The WO 3  nanoframework efficiently absorbs visible light due to multiple reflections in the pores. A rapid charge transfer to graphene takes place, which avoids charge recombination. Additionally, graphene nanosheets are exposed on the surface. This enables π–π conjugation between graphene and dyes leading to high adsorption rates of the substrate o...
