Efficient Inhibition of Deep Conversion of Partial Oxidation Products in C-H Bonds’ Functionalization Utilizing O2 via Relay Catalysis of Dual Metalloporphyrins on Surface of Hybrid Silica Possessing Capacity for Product Exclusion

“…The functionalization of C-H bonds by means of oxidation utilizing molecular oxygen (O 2 ) is an extensively adopted strategy in the industrial utilization of fossil resources containing abundant hydrocarbons [1][2][3][4][5]. And, a troublesome issue in these important industrial processes is the deep conversion of partial oxidation products (POX-products) because POX-products, such as alcohols and ketones, are usually more reactive than substrates like cycloalkanes, alkanes, and alkyl aromatics [6][7][8][9]. Thus, in the field of C-H bonds' oxidation utilizing O 2 , a widely acknowledged fact is that partial oxidation products will be converted further to deep oxidation products along with their formations, especially at high conversion levels, resulting in consumed selectivity towards partial oxidation products induced by improved substrate conversion.…”

Size-dependent electronic interface effect of Pd nanocube-based heterojunctions on universally boosting phenol hydrogenation reactions

“…KA oil (cyclohexanol and cyclohexanone) is an important raw material (with an annual global consumption of one million tons) for the production of various polymers, such as nylon-6, nylon-66, and polyamide resins [1][2][3]. KA oil production mainly relies on phenol hydrogenation [4][5][6][7][8] and cyclohexane oxidation [9][10][11][12], the former providing considerably higher selectivity under relatively mild conditions but requiring expensive catalysts. Pt- [13][14][15] and Pd- [16][17][18] based hetero-geneous catalysts are preferred for hydrogenation because of their good reusability.…”
