Mesoporous films of TiO 2 prepared by a template-assisted procedure based on the evaporation-induced self-assembly mechanism were shown to be efficient photocatalysts for the oxidation of nitrogen oxide. Their high photocatalytic activity is explained by a local increase in the partial pressure of NO in the nanopores of the porous film close to the photocatalytic active sites. Owing to the strong adsorption of the intermediate products, a high selectivity towards nitric acid is achieved.
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
