چکیده

Selective oxidation of active and inactive alcohol substrates is a highly versatile conversion that remains challenging in controlling functionality and adjustments on MOFs. On the other hand, it offers an attractive opportunity to expand their applications in designing the next generation of catalysts with improved performance. Herein, a novel mixed MOF consisting of supported mixed MOF has been fabricated by post-synthetic modifications of IRMOF-3 & IR-MOF-1. Subsequently, to impart catalytic sites, the prepared nanocomposites were modified using palladium chloride ions [1-3]. After successfully designing and structurally characterizing nanocomposites, we evaluated their activity in oxidizing primary and secondary alcohols using aerobic conditions with molecular oxygen and air atmosphere. In addition, the stability of mixed MOF catalysts under catalytic conditions was also demonstrated by comparing the FT-IR spectrum, SEM image and ICP-OES method before and after catalysis. Based on the results, the active surface area of the synthesized nanocatalyst is large, which highlights its unique synergistic effect between post-synthetic modified MOF and Pd and available catalytic sites from that, as demonstrated by outstanding catalytic activity.
