The mesoporous materials SBA-15 and SBA-16 from the self-assembled template organic framework inorganic compound materials are successfully prepared with powder and film states. The powder state of mesoporous material exhibit a variety of properties and possibilities of these kinds of materials. The film state of these SBA-15 and SBA-16 are successfully fabricated into the surface photo voltage (SPV) type gas sensor device as a gas adsorption insulator layer.These kinds of gas sensors device exhibit NO and NO2 gas sensing properties dependent on their mesoporous film structure. We are succeeded in indication about a possibility of mesoporous silicate film for the SPV type gas sensor application.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
