The discovery and design of highly selective, active and stable mesoporous metal oxide catalysts is of vital importance in many applications such as the large-scale production of bulk chemicals, environmental protection, and the generation/distribution of sustainable energy. In this review, we ＇ 11 discuss our recent research oriented toward the rational synthesis of mesoporous metal oxides （MMOs）. The high-degree control over different compositional/structural parameters of MMOs provides a useful material candidate platform to further study their structure-property relationship for the design of better catalyst for a specific reaction. We also introduce a new methodology for the discovery of new catalysts using ink-jet printing （IJP） technology. A general and simple formulation of inorganic inks based on a colloidal, monodispersed in size, nanoparticle system is used for IJP syntheses that enable rapid access to large catalyst libraries （ - 1,000,000 formulations/hour）. In addition, a group testing strategy is used to reduce the number of tests 16000 - fold over exhaustive one-by-one searching. This printer approach is extremely efficient and can help accelerate the identification of optimal catalysts..
