Findings on Chemical Engineering Reported by Investigators at Hong Kong University of Science and Technology (New Pd/SiO2@ZIF-8 Core-Shell Catalyst with Selective, Antipoisoning, and Antileaching Properties for the Hydrogenation of Alkenes)

By a News Reporter-Staff News Editor at Journal of Engineering -- Researchers detail new data in Chemical Engineering. According to news originating from Hong Kong, People's Republic of China, by VerticalNews correspondents, research stated, "In this work, we fabricated a new type of Pd/SiO2@ZIF-8 core-shell catalyst composed of a Pd/SiO2 microsphere as the core and a ZIF-8 membrane as the shell. The preparation procedure involves first loading Pd nanoparticles onto nonporous SiO2 microspheres to obtain the Pd/SiO2 core and then coating a perfect layer of ZIF-8 shell on the core by electrostatic induction to form a Pd/SiO2@ZIF-8 core-shell structure."

Our news journalists obtained a quote from the research from the Hong Kong University of Science and Technology, "It is crucial that the modification of the Pd/SiO2 core with polyelectrolyte was employed to improve the charge distribution of the core surface and preferably adsorb Zn2+ cations in the synthesis solution so as to assist the formation of a continuous ZIF-8 shell. The compactness and thickness of the shell were optimized by increasing the number of cycles of ZIF-8 growth."

According to the news editors, the research concluded: "The hydrogenations of alkenes with different molecular sizes showed that the Pd/SiO2@ZIF-8 catalysts can provide excellent product selectivity and antipoisoning and antileaching properties for the hydrogenations of alkenes."
