photocatalyst การใช้

• Recombination is undesirable and leads to an inefficient photocatalyst.
• Overall, the best photocatalyst has a high quantum yield and gives a high rate of gas evolution.
• The oxidized photocatalyst is then easily returned to its original oxidation state through interaction with one of the reaction additives.
• This transformation is proposed to occur by oxidation of the amine to the aminium radical cation by the excited photocatalyst.
• For this electron-transfer, Ru ( bipy ) 3 2 + was discovered to be an efficient photocatalyst.
• The photocatalyst is strongly oxidizing due to the electrophilicity of iridium and the electron-poor nature of the fluorinated ligands.
• The required change in orbital populations can be achieved by electron transfer with a photocatalyst sensitive to lower energy visible light.
• The latter is one of the most popular inorganic photocatalyst for decomposition of phenol, various dyes and other waste water contaminants.
• 2010-AIST reports a quantum yield of 19 % in photocatalytic water splitting with a caesium-enhanced tungsten oxide photocatalyst.
• A wide variety of pumping systems exist ranging from biological enzyme based pumps, to organic photocatalyst pumps, to metal catalyst pumps.
• A photocatalyst activity indicator ink quickly and easily identifies the presence of an underlying heterogeneous photocatalyst and provides a measure of its activity.
• A photocatalyst activity indicator ink quickly and easily identifies the presence of an underlying heterogeneous photocatalyst and provides a measure of its activity.
• This quantity is a reliable determination of how effective a photocatalyst is; however, it can be misleading due to varying experimental conditions.
• Thus, a less efficient photocatalyst that absorbs visible light may ultimately be more useful than a more efficient photocatalyst absorbing solely light with smaller wavelengths.
• Thus, a less efficient photocatalyst that absorbs visible light may ultimately be more useful than a more efficient photocatalyst absorbing solely light with smaller wavelengths.
• The rate of the rapid colour change associated with photocatalyst activity indicator inks has been directly correlated with the photocatalytic oxidation of stearic acid, and NOx.
• Thick films produced this way allow cheaper and more rapid synthesis relative to sol-gel thin-films, along with higher levels of photocatalyst surface area.
• The photocatalyst then oxidizes an enamine species, transiently generated by the condensation of an aldehyde with a secondary amine cocatalyst, such as the optimal isopropyl benzylamine.
• Goswami was the first to propose a system for photocatalytic air disinfection through the incorporation of photocatalyst material, light source, and filter in existing HVAC systems.
• A second exhibition, " Field of Jeans ", applied the photocatalyst to pairs of denim jeans, to illustrate how it could be used in everyday life.
