Photocatalysis

ABSTRACT Heterogeneous photocatalysis, has been reported to be effective for the degradation of a wide range of model pollutants in suspension. The use of nanostructured materials is one approach to improving photocatalytic efficiency. Therefore, this work is based on the use of nanomaterials such as titania and silver-zinc oxide photocatalysts to degrade amoxicillin trihydrate (a model antibiotic pollutant) in suspension under UV-C irradiation and compares the efficiencies of the photocatalysts

The disposal of colored organic waste water from the textile industries causes serious problems to the aquatic ecosystem and because of this the aquatic environment is contaminated which created a serious threat to the living organisms. Textile industry is water-intensive resulting a large amount of harmful dye effluent 33. The increasing awareness on environment issues the norms are being specified by the governments of various countries 34. In view of complex chemical, molecular structures and

Ternary nanocomposites (NCs) comprising Ag-Cu2O supported on reduced graphene oxide (rGO) with enhanced stability and visible light photocatalytic activity were synthesized via a facile and green approach using Benedict’s solution and glucose solution at room temperature without the need of any toxic reagent, surfactant or any special treatment. Besides mild reducing capability to GO, glucose also induces the functionalization of rGO sheets, preventing the aggregation of the reduced sheets and providing

Recently semiconductor based photo-catalysis as a sort of Green technology which has attracted notable attraction among the researchers. This field has emerged as one of the most promising ways for photo conversion-related technologies by harvesting sun light in environment and energy fields. In general photocatalytic oxidation has been applied broadly in the process of removal of organic pollutants in water and air as a cost-effective and environmentally friendly technology, which could decompose

applications mentioned already, they can be utilized in a number of treatment strategies. For example, photocatalysis can be used for water disinfection to destroy humic substances, viruses and bacteria and even toxic chlorinated compounds. Heavy metals like Hg, Cr, Pb, Cd, As and Ni are removed from water using photocatalysis. Photodynamic therapy is another novelty in the field of photocatalysis. Radicals generated by illumination of light on TiO2 target cancer cells and destroy them2. It should

selected for my graduate study links local electric field maps, photocatalysis, and electron energy loss spectroscopy (EELS). The main goal of this project is to distinguish respective contributions of plasmonic heating and hot electron transfer in nanoantenna (NA)-transition metal dichalcogenides (TMD) heterostructures to decreasing the chemical reaction energy of sustainable Hydrogen (H2) photocatalysis. Enhancement in photocatalysis of hydrogen evolution reaction (HER) has been attributed to both

CO2 are analysed and compared to determine the most suitable method to lower the CO2 concentration within the atmosphere. The use of transition metal, metalloporphyrin and supramolecular catalysts are investigated in depth, as well as Z-scheme photocatalysis. Comparisons of the methods are based upon efficiencies of the catalyst, selectivity and yield of the product and general commercial viability. It was found that the transition metal and supramolecular catalysts were generally more efficient than

Photocatalysis is the acceleration of a chemical reaction by light. The activity of these catalysts usually depends on their ability to produce pairs of negatively charged electrons and positively charged electron holes (electron-hole pairs) on material surfaces, which is induced by light irradiation. An electron hole is the absence of an electron from the full valence band. Furthermore, as light interacts with matter in the form of energy packets, the photons, it excites an electron consequently

Photocatalysis is one of the clean and renewable technologies, utilizes naturally enormous abundant, clean and safe solar power. The cheap solar energy harnessing is one of the most exciting features to gain significant attention toward photocatalysis direction. Titanium oxide-based photocatalyst has shown considerable interest since the discovery because of the excellent properties

environment. Another advantage of this machinery is that it is low-cost and eco-friendly. Recycling of spilled oil and regeneration of the Me-CNT sponges is done primarily by heat treatment. After use, the sponges are gathered by magnets, collected and heated (to 493K to release the gasoline vapour or 573 °C to release diesel). After regeneration, the sponge can be reused multiple times for oil sorption. In fact it can be recycled more than 1000 times. [Xuchun Gui, Zhiping Zeng, Magnetic and Highly
