Rapid Synthesis of Hierarchically Structured Multifunctional Metal-Organic Zeolites with Enhanced Volatile Organic Compounds Adsorption Capacity

The industrial establishment of hierarchical metal-organic zeolites (H-MOZs) is driven by the need for material property, production sustainability, and economic feasible. Here we developed a novel and transferable approach for rapid fabrication of a series of stable H-MOZs using a cation surfactant as template. This significantly enhances the economic sustainability of the conventional process by (i) reducing synthesis temperature to 298 K from high temperatures under the conventional method; (ii) reducing synthesis time to 8 min from several hours; and (iii) increasing the space-time-yield (STY) of H-MOZs to 2.3 X 10(3) kg.m(-3).d(-1), at least 3 orders of magnitude higher than those of conventional hydrothermal synthesis. Furthermore, the porosity of H-MOZs could be efficiently tuned through controlling the type of introduced templates, and this strategy is extendable to prepare stable hierarchical metal organic frameworks (H-MOFs). In addition, the synthetic mechanism of H-MOZs was proposed by means of computational calculations. The resultant H-MOZs showed enhanced gas adsorption performance in the capture of volatile organic compounds (VOCs), reflecting the outstanding potential of the efficient strategy for H-MOZs synthesis at industrial scale and a wide range of applications.
