  • Photo Catalytic Pure Air Purifier it can use for purify air and kill germs
  • What's In Your Air? Select air purifier manufacturers are now utilizing Photocatalytic Oxidation (PCO) technology as a way of removing particulate matter, microbes, gasses and odors from the air. This air purification technology is the most advanced yet. Essentially, PCO technology combines UV rays with a special multi-metal nano catalyst, which creates hydroxyl radicals and super-oxide ions, which are highly reactive electrons. These highly reactive electrons aggressively combine with polluting elements in the air, such as bacteria and VOCs. Once bound together, a chemical reaction takes place between the super-charged ion and the pollutant, effectively "oxidizing" (or burning) the pollutant. This breaks the pollutant down into harmless carbon dioxide and water molecules, making the air more purified. This DVD first highlights the pervasive problem that indoor air pollution causes, then explains how PCO technology works and how it can dramatically purify air making a healthier and happier home. Several experts are interviewed further underscoring the credibility of PCO technology, including Nabarun Ghosh, PhD, Jeff Bennert PhD, CTN and others. 23 minutes.

  • Photocatalytic performance of fabric coated with nano TiO2 This experiment proves the outstanding photocatalytic activity of our product: fabric coated nano TiO2. Transcript: This experiment proves the high photocatalytic activity of our product: nano crystalline titanium dioxide coated onto fabric. In the experiment, we used a piece of fabric coated with nano titanium dioxide, methylene blue solution, pH indicator paper , lemon, and distilled water. First, put the piece of fabric coated with nano titanium dioxide into the flask. Pour some distilled water in it Then, soak and stir the flask, so that the fabric is totally wet. Decant water into the petri-dish Put a piece of PH indicator paper into the water. We can see that its color is not changed. Squeeze lemon juice into the petridish. Color of the indicator changes to orange as a result of acid in lemon juice. This shows that the fabric coated with titanium dioxide is chemically neutral. Now is main stage of the experiment Pour methylene blue on to the fabric Stir the solution so that the reaction occur quickly Decant treated solution into the petridish We can see that obtained solution is totally transparent. This means that methylene blue is degraded quickly and completely. Now lets repeat the procedure with the same fabric. This time, once again, methylene blue is totally decomposed. Now, The same procedure is repeated for the third time. Methylene blue is still completely degraded Note that the entire experiment is taken place under indoor light. The result shows that our ...

  • TiO2 Photocatalytic Membrane: DigInfo Taiyo Kogyo showcased its new "titanium oxide photocatalytic membrane" tent material at Architecture & Construction Materials 2008. The company uses its proprietary comprehensive software for the design, structural ***ysis, engineering, and construction of membrane structures, including the roof construction of the Tokyo Dome. Taiyo Kogyo's new photocatalytic tent material is both weather and self-cleaning. The dirt on the photocatalytic tent is cleaned by oxidative decomposition, which dissolves organic matters on the surface of the tent membrane. The super-hydrophilicity of the titanium oxide photocatalytic membrane allows water to penetrate underneath stains to slough them off the membrane surface. The use of titanium oxide photocatalytic membrane tent material greatly increases solar reflectance, and this in turn contributes significantly in controlling interior room temperature. As a result, air conditioning efficiency is improved, reducing operating costs and adverse environmental impacts. The membrane also cuts harmful ultraviolet rays by about 98 percent, helping prevent product quality degradation at high temperature and ultraviolet rays from causing color fade. Taiyo Kogyo intends to market this new titanium oxide photocatalytic membrane tent material for use in walls and roofs of residential homes.

  • Tio-UV : DigInfo DigInfo - movie.diginfo.tv By applying the decoloration effect principle for a chemical reaction that results when methylene blue on the surface of titanium dioxide is irradiated with ultraviolet light with a wavelength of 365nm, it is possible to measure the decoloration concentration at that point by optically measuring the reflectance obtained using a semiconductor laser with a wavelength of 700nm. The quantitative concentration value of titanium dioxide is obtained by comparing the standard level of titanium dioxide measured using a spectrophotometer. Photocatalyst products (glass, wood products, polymers, motor vehicle interior and construction materials) can be used in a wide variety of raw materials and finished products. Photocatalysts can be used in the non-contact measurement of objects so as to preserve their purity, and can even be used to make measurements regardless whether the instrument is flat, spherical, or protruded. Since the reagent is not affected by oxidation, it is possible to make high-precision measurements and improve the reproducibility system. The lightweight detector probe makes it easy to adjust measurement points. In addition, it can be mounted on a camera tripod, and powered by either 2 AC batteries, it is portable enough to be use for making measurements at construction sites.

  • Solar-Driven Photocatalytic Formation of Hydrogen from Water by Department of Chemistry The Chinese University of Hong Kong
  • Green Millennium Photocatalyst TiO2 Solar Clean Technology Nano TiO2 Photocatalyst Coating Technology: The principle of TiO2 ( Titanium Dioxide ) photocatalytic reaction was to accelerate the nature's cleaning and purifying process using light as energy. Discovered in 1960's, Dr. Fujishima of Japan found titanium metal, after irradiated by light, could break water molecule into oxygen and hydrogen gas. By restructuring titanium dioxide particles in nano-scale, a number of new physical and chemical properties were discovered. One of these newfound effects was photocatalytic oxidation which accelerated the formation of hydroxyl radical, one of the strongest oxidizing agents created by nature. Using energy found in the UV light, photocatalyst titanium dioxide could breakdown numerous organic substances such as oil grime and hydrocarbons from car exhaust and industrial smog, volatile organic compounds found in various building materials and furniture, organic growth such as fungus and mildew. In addition to its photocatalytic oxidation effect, titanium dioxide coating also exhibited hydrophilic property (or high water-affinity) which titanium dioxide coating attracted water moist in the air to form an invisible film of water. This thin film of water allowed the substrate to be anti-static so the coated surface could be easily cleaned by rinse of water. For years, titanium dioxide was used in many commodity products such as paint, cosmetics, sun blocks, and etc. It is a safe and stable substance commonly found ...
