[Display omitted] Methanol is a promising hydrogen carrier for fuel cell vehicles (FCVs) via methanol steam reforming (MSR) reaction. Ceria supported copper catalyst has attracted extensive attentions due to the extraordinary oxygen storage capacity and abundant oxygen vacancies. Herein, we developed a colloidal solution combustion (CSC) method to synthesize a porous Cu/CeO 2 (CSC) catalyst. Compared with Cu/CeO 2 catalysts prepared by other methods, the Cu/CeO 2 (CSC) catalyst possesses highly dispersed copper species and abundant Cu+-O v -Ce3+ sites at the copper-ceria interface, contributing to methanol conversion of 66.3 %, CO 2 selectivity of 99.2 %, and outstanding hydrogen production rate of 490 mmol g cat −1 h−1 under 250 °C. The linear correlation between TOF values and Cu+-O v -Ce3+ sites amount indicates the vital role of Cu+-O v -Ce3+ sites in MSR reaction, presenting efficient ability in activation of water. Subsequently, a deep understanding of CSC method is further presented. In addition to serving as a hard template, the colloidal silica also acts as disperser between nanoparticles, enhancing the copper-ceria interactions and facilitating the generation of Cu+-O v -Ce3+ sites. This study offers an alternative approach to synthesize highly dispersed supported copper catalysts. [ABSTRACT FROM AUTHOR]

d6r units were proved to be crucial for the synthesis of SSZ-16 zeolite with AFX topology, and FAU zeolite owning plenty of d6r units was chosen as the essential raw material for constructing AFX frameworks. In this work, SSZ-16 zeolite was directly synthesized using colloidal silica and sodium aluminate as the raw materials in short crystallization time of 5 h. The corresponding crystallization process were carefully investigated by various characterizations, demonstrating that the key to this success was the formation of d6r units built up by a large amount of s4r units which were formed with the assistance of the appropriate organic structure directing agent (OSDA) and seeds in the synthetic media. Interestingly, the products of C-SSZ-16 zeolites presented spherical shapes consisted of relatively small particles with size range from 30 to 50 nm. Moreover, after ion-exchanged with Cu ions, the Cu-C-SSZ-16 products showed excellent performance in the selective catalytic reduction of NO x with NH 3 (NH 3 -SCR) and better hydrothermal stability than conventional Cu-SSZ-16-con samples due to slightly higher Si/Al ratio of the Cu-C-SSZ-16. Therefore, remarkable catalytic performance and the use of low-cost raw materials as well as short period of synthesis time make AFX zeolites as potential applicants in NH 3 -SCR field, from an industrial viewpoint.
