摘要： The present invention is directed to a sheet-form environment purifying material comprising particles of metal and/or metal oxide consisting essentially of at least one member being selected from the group consisting of manganese, copper, zinc, iron, vanadium, nickel, titanium, palladium, platinum, manganese oxide, copper oxide, zinc oxide, iron oxide, vanadium oxide, nickel oxide, titanium oxide, palladium oxide, and platinum oxide, adsorbent particles consisting essentially of at least one member selected from the group consisting of activated carbon, zeolite, silica gel, sepiolite, activated alumina and activated clay, thermoplastic resin particles being selected from ultrahigh-molecular weight polyethylene, polyethylene, polycarbonate, polyamide acrylonitrile-butadiene-styrene resins, polyimide, polyvinyl chloride, cellulose acetate, polysulfone, polystyrene phthalate and polypropylene, and an air-permeable sheet of fibrous. The metal and/or metal oxide particles and the adsorbent particles are respectively bound to the thermoplastic resin particles while retaining their inherent surface areas and performances without being covered by the thermoplastic resin layers, and the thermoplastic resin particles are joined to the fibrous substrate. The present invention is also directed to a process for making the environment purifying material which comprises the steps of mixing all the particles and heating the mixture at a temperature not lower than the melting point of the thermoplastic resin and not higher than the thermal decomposition temperature thereof. The environment purifying material of the present invention is useful as deodorizers and harmful gas removers.
