摘要： The present invention provides: an interior material having a surface layer which has visible light-responsive photocatalytic activity and which contains two types of titanium oxide microparticles, the two types of titanium oxide microparticles comprising first titanium oxide microparticles, in which a tin component and a transition metal component for enhancing visible light responsiveness (excluding iron group components) are in solid solution, and second titanium oxide microparticles, in which an iron group component is in solid solution; and a method for manufacturing the interior material. The present invention makes it possible to provide an interior material in which visible light-responsive photocatalytic titanium oxide microparticles, which make it possible to easily produce a surface layer (photocatalyst thin film) having high transparency and expressing photocatalytic activity even in response to visible light (400-800 nm) only, are applied onto a surface, whereby it is possible to obtain, under indoor illumination, excellent photocatalytic properties such as an antimicrobial property and a property of breaking down chemical substances in indoor air without adversely affecting the design quality of the article in question.

摘要： The present disclosure is directed to a catalytic composite that comprises porous supported catalyst particles durably enmeshed in a porous fibrillated polymer membrane. The supported catalyst particles are composed of at least one metal or metal oxide catalyst dispersed on a porous support substrate. In some embodiments, the porous fibrillated polymer membrane is perforated or otherwise contains mechanically formed holes therein. The supported catalyst particles have a large particle population based, at least in part, a D90 value greater than 60 microns. The catalytic membrane composite may be used in filtration applications to remove air-polluting substances such as SOx, NOx, dioxin/furan, CO, and others and convert them into non-polluting or less-polluting gas components. Additionally, the catalytic article may be in the form of a filter bag, a honeycomb, a monolith or any other suitable geometrically structured forms.
