Despite the considerable potential of single-atom catalysts in water and wastewater treatment, large-scale production is still challenging. A multidimensional coordination approach provides a practical and cost-effective method for the mass production of single-atom catalysts. Zhong-Shuai Zhu Yantao Wang ...
Post-synthetic preparation of Sn-, Ti- and Zr-beta: a facile route to water tolerant, highly active Lewis acidic zeolites Hammond C et al (2014) Post-synthetic preparation of Sn-, Ti- and Zr-beta: a facile route to water tolerant, highly active Lewis acidic zeolites. ... P Wolf,C ...
High permeability and high relative density are the design goals for robust and high-throughput metamaterials for the applications of high-efficient matter transportation without the reaction between liquid and solid. However, we consider that in the application of metamaterial catalysts, having relatively...
The hydrogenation via catalytic method is one of the promising techniques for removal of nitrate from water. It needs very active catalysts because the reaction is performed preferably at an ambient/low temperature. The reaction scheme shows that nitrate is reduced to the desired products involving ...
Indeed, it is known that the most important properties of catalysts are activity, selectivity, and stability, which depend on factors such as temperature, pressure, nature, and purity of the reagents. The presence of impurities in the mixture can lead to deactivation of the catalyst due to the...
Although the high interest in photocatalytic oxidation/ozonation disinfection, the use of catalysts in their powder form is an important disadvantage, since a solid/liquid separation step must be designed [157]. Thus, research in that field should focus on the development of structured catalysts ...
