Kinetic study of adsorption and photo-decolorization of Reactive Red 198 on TiO2 surface [PDF]
, 2009 Recycling and reuse of wastewater after purification will reduce the environmental pollution as well as fulfill the increasing demand of water. Adsorption-based water treatment process is very popular for dye-house wastewater treatment. The present study

Advanced Science, EarlyView.An anisotropic dual S‐scheme heterojunction (C3N4/SubPc‐1/C3N5) is constructed to overcome the electron–proton kinetics mismatch in photocatalytic H2O2 production. The imide bridge serves as a dual channel for ultrafast electron transfer and proton relay, synergistically enabling efficient dual‐pathway oxygen reduction and achieving a high H2O2 ...

Electrochemical reduction of azo dyes mimicking their biotransformation to more toxic products
Journal of Veterinary Research, 2019 Some azo dyes, including Sudans I–IV and Para Red, are genotoxic and may be biotransformed to cancerogenic aromatic amines. They are banned as food and feed additives, but their presence has been detected in food.

Predicting dye biodegradation from redox potentials [PDF]
, 2004 Two biological approaches for decolorization of azo sulfonated dyes have been compared: reductive decolorization with the ascomycete yeast Issatchenkia occidentalis and nzymatic oxidative decolorization with Trametes villosa laccase alone or in the ...

Copper Contact for Perovskite Solar Cells: Properties, Interfaces, and Scalable Integration
Advanced Energy and Sustainability Research, EarlyView.Copper electrodes, as low‐cost, scalable contacts for perovskite solar cells, offer several advantages over precious metals such as Au and Ag, including performance, cost, deposition methods, and interfacial engineering. Copper (Cu) electrodes are increasingly considered practical, sustainable alternatives to noble‐metal contacts in perovskite solar ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT This study examined the degradation of Reactive Red 180 and safranin using zinc oxide photocatalysis. Complete dye removal was achieved for both dyes under optimal conditions within 2 h. For Reactive Red 180, the optimum conditions were pH 10, 0.5 g/L zinc oxide, 25 ppm dye concentration, and 1 L volume. For safranin, the conditions were pH 10,

Some Peculiarities of Creation of Stable Polyimide - Azo Chromophore System
Eurasian Chemico-Technological Journal, 2001 Azo dyes: methyl orange, methyl red, congo red have been suggested as doping agents for formulation of stable soluble azo dye - polyimide (PI) system according to guest-host scheme. The dyes were added to the reactive mixture of monomers: dianhydrides of
