O livro demonstra o processo de sÃntese de semicondutor de óxido metálico e grafeno/rGO para aplicações de sensores de gás com o objetivo de desenvolver um sensor eficiente de gás hidrogénio à temperatura ambiente usando estrutura nanohÃbrida de heterojunção n-ZnO/p-rGO em apoio à crescente procura de baixo custo, fabrico simples, sistema de monitorização de hidrogénio gasoso de longa duração, estável, excecionalmente sensÃvel e seletivo, especialmente para garantir a segurança industrial. sensÃveis a gases e estuda o comportamento de sensibilidade de os filmes revelados para a deteção de hidrogénio. Uma técnica de deposição quÃmica de baixo custo tem sido utilizada para depositar o filme fino de NPs de ZnO. Os estudos deste livro foram feitos sobre a resposta do sensor sob diferentes concentrações de gás. Uma técnica de esfoliação electroquÃmica simples e de baixo custo tem sido utilizada para sintetizar o Grafeno /rGO. Os espectros Raman determinam a cristalinidade, bem como o número de camadas de grafeno presentes na amostra.
