Obviously, due to its energy saving and friendly environmental, photocatalytic reduction of [N.sub.2] to N[H.sub.3] could be an excellent alternative to the Haber-Bosch process.
According to the company, the funds will be used in advancing a new photocatalytic chemical reactor powered by light from renewable electricity instead of heat from burning fuel.
Summary: TEHRAN (FNA)- Researchers have developed a photocatalytic system based on a material in the class of metal-organic frameworks.
[13] synthesized pure anatase, pure rutile, and mixed anatase-rutile cake-like particles and observed that anatase-rutile particles reached higher photocatalytic activity compared to powders of pure phases (anatase and rutile) and also higher than P25.
In recent advances in efficient photocatalytic systems, the synthesis of high-performance photocatalysts with good recyclability is the one of the most important purposes; deplorably, the broad band gap of metal oxides confines the reasonable maintenance under visible light [18].
To improve their visible light-driven photocatalytic activities, approaches are adopted, mainly including doping and preparation of plasmonic photocatalyst [12, 13].
Photocatalytic coatings, on the other hand, allow the decomposition of organic pollutants on the surface of the textiles [4,5].
Ti[O.sub.2] possesses antibacterial properties due to its strong oxidation activity in the presence of light and the generation of reactive oxygen species such as hydroxyl radicals ([sup.*]OH), hydrogen peroxide ([H.sub.2][O.sub.2]), and superoxide ions ([O.sub.2.sup.*-]) from photocatalytic reaction [7].
The photocatalytic activity and stability of immobilized PU/Ti[O.sub.2] were evaluated by measuring the photocatalytic degradation efficiency of methyl orange.
