UV-Induced Photocatalytic Cashmere Fibers
Cashmere with UV-induced photocatalytic properties is developed for the first time by applying nanocrystalline anatase TiO₂ colloid that is free of inorganic acids and organic solvents via a facile low-temperature one-step sol-gel process. The coated cashmere exhibits remarkable UV-induced photodegradation of methyl orange. Furthermore, the photocatalytic nano-coating on cashmere exhibits signi...
متن کاملUV/TiO2 photocatalytic degradation of xanthene dyes.
UV/titanium dioxide (TiO(2)) degradation of two xanthene dyes, erythrosine B (Ery) and eosin Y (Eos), was studied in a photocatalytic reactor. Photocatalysis was able to degrade 98% of Ery and 73% of Eos and led to 65% of chemical oxygen demand removal. Experiments in buffered solutions at different initial pH values reveal the pH dependence of the process, with better results obtained under ac...
متن کاملUV polymerization of hydrodynamically shaped fibers.
Most natural and man-made fibers have circular cross-sections; thus the properties of materials composed of non-circular fibers are largely unexplored. We demonstrate the technology for fabricating fibers with predetermined cross-sectional shape. Passive hydrodynamic focusing and UV polymerization of a shaped acrylate stream produced metre-long fibers for structural and mechanical characterizat...
متن کاملHigh efficient degradation of Cefixime using UV/TiO2 photocatalytic process: A comparison between photocatalytic and photolytic
Introduction: The existence of pharmaceuticals in aquatic ecosystem, their persistence and possible effects on living organisms and inefficient systems in removal of these compounds from water and wastewater are a growing concern. In this research, the UV/TiO2 photocatalytic degradation of Cefixime was investigated so as to identify if this method was efficient for removal of Cefixime or not. ...
متن کاملOptofluidic UV-Vis spectrophotometer for online monitoring of photocatalytic reactions
On-chip integration of optical detection units into the microfluidic systems for online monitoring is highly desirable for many applications and is also well in line with the spirit of optofluidics technology-fusion of optics and microfluidics for advanced functionalities. This paper reports the construction of a UV-Vis spectrophotometer on a microreactor, and demonstrates the online monitoring...
