Structural Evolution of Anatase‐Supported Platinum
WebAnatase is a metastable mineral form of titanium dioxide (TiO 2) with a tetragonal crystal structure. Although colorless or white when pure, anatase in nature is usually a black solid due to impurities. Three other polymorphs (or mineral forms) of titanium dioxide are known to occur naturally: brookite, akaogiite, and rutile, with rutile being the most common and … WebJun 15, 2004 · A nanostructured anatase supported V–O–Mo catalyst with V:Mo:Ti=1:9:90, obtained by sol–gel method from inorganic substrates, was investigated.
