The aim of this work was to prepare materials for use in buildings depollution, formed by titanosilicate microcrystals immobilized on ceramic surfaces, combining their unique properties, including the photo-catalytic properties of titanosilicates with high mechanical strength, with the thermal and chemical stability of the ceramic materials. In particular, titanosilicates, ETAS-10, belonging to the family of ETS (Engelhard titanium silicate), were studied. Keywords: titanosilicate, ETAS-10, ETS-10, ceramic material, ceramic support, microcrystal, zeolite, multifunctional material, hydrothermal reaction, photocatalytic material. 1 Introduction Today's environmental problems are forcing the search to find new materials with low environmental impact capable of responding to the increasingly looming ecological requirements. Through the development of knowledge and technology, new materials used in building and construction have undergone a considerable evolution in response to new standards of quality and possessing new and more articulate properties [1]. The application of new techniques to ceramic materials is a broad experimental field and involves a wide range of possible applications and uses so that, through coupling them with other materials, such as zeolites, new characteristics to the traditional properties of ceramic materials can be added. The various applications of zeolites derive directly from their unique and diverse properties as ion exchange, catalysis, adsorption, molecular sieving [2],
