Ecomateriais: desenvolvimento e aplicação de materiais porosos funcionais para proteção ambiental

Abstract: Recebido em 10/2/06; aceito em 25/4/06; publicado na web em 28/11/06 ECOMATERIALS: DEVELOPMENT AND APPLICATION OF FUNCTIONAL POROUS MATERIALS FOR ENVIRONMENTAL PROTECTION. Fundamental aspects of the conception and applications of ecomaterials, in particular porous materials in the perspective of green chemistry are discussed in this paper. General recommendations for description and classification of porous materials are reviewed briefly. By way of illustration, some case studies of materials design and applic… Show more

“…Because of these properties, such materials have been considered promising candidates for use as catalyst supports, gas sensors, thermal insulators, and other related applications 9 . Because of their physicalchemical characteristics, porous ceramic materials can also be used in environmental applications, such as sensing and the remediation of effluents through selective adsorption of chemical species 10 , and in engineering processes as substitutes for metallic and polymeric materials, especially those used at high temperatures 11 …”

“…Moreover, the difficulty in reproducing results with porous ceramic materials is the main limitation of its use 12,13 . In this sense, various methods of preparing porous ceramics have been evaluated in recent years in attempts to obtain materials with complex geometries and microstructures designed for specific applications without the need for a machining step 10 . With respect to porous ceramics, one of the oldest and still widely used preparation methods is related to the incorporation of organic products inside the ceramic bodies, which are removed during the heat treatment step.…”

“…Assim, é evidente a necessidade de novas tecnologias para uma produção ambientalmente adequada. 1 Ao longo de décadas, a atividade industrial tem produzido rejeitos gasosos, líquidos e sólidos nocivos ao meio ambiente. Os processos industriais que utilizam grandes volumes de água contribuem significativamente com a contaminação dos corpos d'água, principalmente por metais, que têm seu impacto ambiental aumentado pela falta de tratamento dos efluentes.…”

“…Nos sólidos denominados porosos, a presença de poros é proveniente da existência de cavidades, canais ou interstícios (FERREIRA et al, 2007). Classificados quanto ao estado de continuidade, tamanho e morfologia, a presença de poros em escalas variadas contribui para a formação de amostras com características físicas e microestruturais particulares (FERREIRA et al, 2007;NANKO, 1998a;RILEY et al, 1965).…”

Neste contexto se inserem as cerâmicas porosas que, aliando matérias-primas de diferentes origens com diversificados processos de fabricação, produzem amostras empregadas em variados fins.…”
