Facile synthesis of ultra-stable Co-N-C catalysts using cobalt porphyrin and peptides as precursors for selective oxidation of ethylbenzene

Single and dual metal atom catalysts for enhanced singlet oxygen generation and oxygen reduction reaction

“…2 Previous studies have devoted tremendous efforts to SACs for various electrochemical reactions. [3][4][5][6][7][8][9][10] However, the application of SACs and DACs for photochemical reactions such as 1 O 2 sensitization, the CO 2 reduction reaction (CO 2 RR), the oxygen reduction reaction (ORR), the hydrogen evolution reaction (HER), the N 2 reduction reaction (NRR), and photoinduced electron/energy transfer reversible addition-fragmentation chain transfer (PET-RAFT) polymerization has rarely been reported. 11,12 More specically, 1 O 2 sensitization can be used for organic synthesis, wastewater treatment, and photodynamic therapy (PDT).…”

Full use of factors promoting catalytic performance of chitosan supported manganese porphyrin

“…immobilized metalloporphyrins and their catalysis systems [31][32][33][34][35] adapting to the cleaner production process. However, the resulting yields (acetophenone and phenylethanol (ONE + OL), less than 25%) were lower than those obtained from the catalytic systems above [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] . In addition, RSM was also seldom used in the catalytic field of metalloporphyrins [14][15][16][17]19,20,[31][32][33][34][35] .…”

“…However, up to date the oxidation techniques used are not very satisfactory yet: There were mainly lack of cleaner production techniques, for examples, O 2 was not used as oxidant, toxic solvents were used, some energy saving and emission reduction had not been done, and so on. Therefore, the catalyst preparation 21 – 25 , the catalytic oxidation system and the oxidation conditions 7 – 20 , which are satisfactorily meeting to the cleaner production process should be comprehensively considered. Based on the above considerations, the internal influencing factors on the catalytic performance of catalyst should be further reasonably tuned, and the external influencing factors should be optimized via Response Surface Methodology (RSM).…”

Heterogeneous M-N-C Catalysts for Aerobic Oxidation Reactions: Lessons from Oxygen Reduction Electrocatalysts

“…Ethylbenzene oxidation − and other arylalkane oxidations − have been reported in the presence of M-N-C catalysts, but the role of the M-N-C is unclear, as many studies report nonzero yields in blank reactions and with metal-free solids, suggesting a potential role of radical-chain pathways that could be modulated by the M-N-C. Oxidation of internal diols or esterification of benzylic ketones, both requiring C–C oxidative cleavage, also could feature radical pathways. , …”
