Abstract: In a formulation comprising titanium dioxide as a photocatalyst and an amphoteric metal oxide (alumina or the like) or a basic metal oxide (barium oxide, strontium oxide or the like) as a material having a base point, when a nitrogen oxide (nitrogen monoxide) comes into contact with or approaches titanium dioxide, upon exposed to light, the carbon monoxide is oxidized to nitrogen dioxide (gas) by hydroxy radicals as an active oxygen species produced by titanium dioxide. As is apparent from the molecular structure, nitrogen dioxide is an acidic gas, alumina is an amphoteric metal oxide, and barium oxide and strontium oxide are a basic metal oxide. The oxygen atom thereof serves as a base point to an acid gas. Therefore, nitrogen dioxide is attracted and chemically bonded to the oxygen atom, held on the metal oxide, and kept close to titanium dioxide as the photocatalyst.

Abstract: In a catalyst body using a direct support, this invention provides a ceramic catalyst body capable of adjusting catalyst performance in accordance with intended objects such as prevention of deactivation of a main catalyst component when an sub catalyst component is used, or improvement of initial purification performance. When both main catalyst component and sub catalyst component are supported on a ceramic support capable of directly supporting the catalyst components, the invention first supports a catalyst metal as a main catalyst such as Pt, for example, and then supports the sub catalyst such as CeO2 on the main catalyst. The main catalyst is thus prevented from being involved in the grain growth of the sub catalyst, and becomes a catalyst body that does not easily undergo thermal deactivation. The ceramic support uses cordierite, a part of the constituent elements of which are replaced, so that the replacing elements so introduced can directly support the catalyst components. The bonding strength of the catalyst components can thus be improved and the thermal durability of the catalyst can also be improved.

Abstract translation: 在使用直接载体的催化剂体中，本发明提供一种能够根据预期目的调节催化剂性能的陶瓷催化剂体，例如在使用副催化剂组分时防止主催化剂组分失活或提高初始纯化性能 。 当主催化剂组分和次催化剂组分两者负载在能够直接负载催化剂组分的陶瓷载体上时，本发明首先例如支持催化剂金属作为主要催化剂例如Pt，然后支持次催化剂如CeO 2 在主催化剂上。 因此，可以防止主催化剂参与副催化剂的晶粒生长，成为不容易发生热失活的催化剂体。 陶瓷载体使用堇青石，其组分的一部分被替换，使得如此引入的替代元素可直接支撑催化剂组分。 因此可以提高催化剂成分的结合强度，也可以提高催化剂的耐久性。
