    Abstract: Mesoporous nanocrystalline titanium dioxide heterojunction materials are disclosed. In one disclosed embodiment, materials comprising a core of titanium dioxide and a shell of a molybdenum oxide exhibit a decrease in their photoadsorption energy as the size of the titanium dioxide core decreases.

    Abstract: A titania-based porous substance includes titania as a principal ingredient, and exhibits an x-ray diffraction peak resulting from lattice planes whose spacing falls in a range of 0.290null0.002 nm. Thus, it includes crystals other than the anatase phase crystal. Therefore, a large number of crystal planes exist therein. As a result, when a catalytic ingredient is loaded on it, the catalytic ingredient is loaded with a lowered rate within the identical crystal plane.

    Abstract: A process and catalyst for the direct oxidation of an olefin having three or more carbon atoms, such as propylene, by oxygen to the corresponding olefin oxide, such as propylene oxide. The process involves contacting the olefin with oxygen under reaction conditions in the presence of hydrogen and in the presence of a catalyst. The catalyst comprises gold on a titanosilicate, preferably a microporous or mesoporous titanosilicate, such as, TS-1, TS-2, Ti-beta, Ti-ZSM-48, or Ti-MCM-41. Selectivity to the olefin oxide is high at good conversions of the olefin. The catalyst is readily regenerated, and the time between catalyst regenerations is long.

    Abstract: This catalyst for purifying exhaust gases can suppress an active ingredient, such as an alkali metal, which reacts with a substrate from moving to the substrate, thereby preventing a decrease in strength such as thermal shock resistance of the substrate. In production, first, a first oxide layer composed mainly of an oxide which has a high reactability with the active ingredient is formed on the substrate. Next, a second oxide layer composed mainly of an oxide which has a low reactability with the active ingredient is formed on the first oxide layer. Then, a catalyst layer loaded at least with a noble metal and the active ingredient is formed on the second oxide layer. This second oxide layer suppresses transfer of the active ingredient and some active ingredient which has passed through the second oxide layer is caught by the first oxide layer owing to its reaction.
