Esta monografia apresenta uma panor mica abrangente dos solventes eut cticos profundos (DES), real ando as suas carater sticas estruturais, propriedades fundamentais e aplica es emergentes na qu mica verde e na ci ncia dos materiais. Uma an lise comparativa dos l quidos i nicos e dos DES real a as suas vantagens e limita es, fornecendo um quadro s lido para a compreens o do papel nico dos DES como uma alternativa sustent vel aos solventes convencionais. dada especial aten o classifica o dos l quidos i nicos de acordo com a sua composi o e ao estudo das principais propriedades f sico-qu micas, incluindo a viscosidade, a condutividade i nica, a estabilidade eletroqu mica e a capacidade de solv ncia. Estas carater sticas determinam a versatilidade dos DES nos processos qu micos e o seu potencial de aplica o industrial.A monografia tamb m examina o papel dos DES nos processos de polimeriza o e a sua aplica o como meio de electross ntese controlada. Em particular, aborda o desenvolvimento de fotocatalisadores e electrocatalisadores multifuncionais de uma nova gera o baseada em tit nio obtido a partir de l quidos i nicos eut cticos, demonstrando as perspectivas dos SF para aplica es energ ticas e ambientais avan adas.

pokkari
The theory and practice of controlled electrochemical synthesis of lead dioxide-surfactant composite catalysts from nitrate bath have been investigated. The focus is on establishing the relationship between synthesis conditions, composition, properties and electrocatalytic activity. Obtained results concerning synthesis and physico-chemical properties can contribute substantially to a fundamental understanding of the relationship between the coating structure and catalytic activity, important to all fields of catalysis.
