Hydrogen evolution coupled with the photochemical oxygenation of cyclohexene with water was observed in the system sensitized by Sn(IV)-porphyrin adsorbed on Pt loaded TiO2 nano-particles in aqueous acetonitrile solution upon visible light irradiation.
6-Phosphate aminopurine (PA), a purine analog, is usually used in clinical anticancer treatment and biochemical research. Up to now, to the best of our knowledge, no literature about the electrochemical behaviors of PA has been reported. In this study, nano-p–n junction heterostructures based on TiO2 nanobelts were produced by the assembly of p-type semiconducting NiO nanoparticles onto the n-t...
در این پایان نامه، tio2-hclo4 nano به عنوان یک نانوکاتالیزور قابل بازیافت و موثر به منظور محافظت و محافظت زدایی از گروه های عاملی مختلف و همچنین موثر در تسریع سنتز یکباره چند جزئی ترکیبات آلی معرفی شده است. در این مطالعه سایلیله شدن الکل ها و فنول ها توسط هگزامتیل دی سیلازان و محافظت زدایی از آن ها در حضور کاتالیزور tio2-hclo4 مورد بررسی قرار گرفت. کاتالیزور tio2-hclo4 همچنین ...
TiO2 and especially its nano-metric structure have many applications for environmental proposes. It can be used in mobilized or immobilized status, but its consumption is less in immobilized form and its process would be economical. In addition, the environmental problems would be minimized. There are a few methods for immobilization of nano-TiO2 inside the process. The sol-gel method is typica...
The present study seeks to investigate the capacity of polyaniline/titanium dioxide (PAn/TiO2) and Polypyrrole/titanium dioxide (PPy/TiO2) nano-adsorbents to adsorb Congo red anionic dye (CR) from aqueous solution. The variables effective in CR adsorption, including adsorbent dose, pH of the solution, contact time, initial dye concentration, and temperature were examined. The study yielded the ...
adsorption capacity of 4-chloro-2-nitrophenol (4c2np) onto nano-ti02 from aqueous solutions wasinvestigated in a batch system by considering the effects of various parameters like contact time, nano-tio2 dosage, initial ph and initial 4c2np concentration. optimum conditions for 4c2np adsorptionwere found to be initial ph z 2, nano-tio2 closer- 0.01 g and equilibrium time 1 h. the adsorptionkine...
[Abstract] In order to fabricate new dye-sensitised solar cell, we proposed a new photoresponsive electrode structure using bio nano process. Carbon nanotube-TiO2 hybrid materials having multitudious nano-sclae cavities were realized using a bifunctional cage-shaped protein possessing carbonaceous material-binding peptides and Ti-binding peptides. The obtained structure was confirmed to consist...
The nanotechnology industry is growing rapidly, leading to concerns about the potential ecological consequences of the release of engineered nanomaterials (ENMs) to the environment. One challenge of assessing the ecological risks of ENMs is the incredible diversity of ENMs currently available and the rapid pace at which new ENMs are being developed. High-throughput screening (HTS) is a popular ...
In the work, influence of shape filler nanoparticles on optimal size agglomerates, at which maximum level impact strength epoxy nanocomposites is achieved, determined. It shown that morphology and agglomerates in oligomer, both nano- (up to ~ 100 nm) micro-levels 390 nm), practically do not change during curing process when binder passes from liquid solid state (matrix). has been established fo...
