“…Then, an 88% bitumen recovery from oil sand and a 42% sulfur reduction from bitumen was fulfilled using the same reagents, the same reaction conditions and ultrasonic parameters simultaneously. In addition, possible metalloporphyrins [146] , [147] , [148] in bitumen can accelerate the UAODS reaction of bitumen. Moreover, it was stated that since ionic NaOH cannot dissolve oil sand sufficiently and effectively, mid-polar THF is used owing to its high dissolving power.…”

“…Wang and co-workers , studied the enhanced effect of the weak anionic ligand of iron porphyrins on the ROS generation efficiency in the oxidation of DBT. Zhou and co-workers also reported the boosted oxidation of dibenzothiophene based on the electron-withdrawing group substituted iron porphyrin complex. Therefore, it is feasible to tune the electronic properties of metalloporphyrin for the ODS process with high performance.…”

Tailoring electronic properties of the central metal atom of metalloporphyrin has emerged as a practical approach to acquire a high catalytic performance. Herein, 5,10,15,20-tetraphenylporphyrin manganese chloride (TPPMnCl) was immobilized on hexagonal boron nitride (h-BN) and employed as a catalyst to achieve ultradeep aerobic oxidative desulfurization of diesel at room temperature. The interfacial electronic effect on the TPPMnCl induced by the h-BN was embraced, leading to an electron transfer from Mn to h-BN. The resulting high-valence Mn could facilitate the generation of reactive oxygen species from the reduction of oxygen. As a result, 99.2% of refractory aromatic sulfur removal for model diesel could be achieved at 30 °C using immobilized TPPMnCl and oxygen as the catalyst and oxidant, respectively. Besides, the catalytic mechanism was studied in detail, and the peroxyacid was found to be generated on the immobilized TPPMnCl as the active species. This study provides a strategy toward tailoring the electronic properties of TPPMnCl on h-BN for enhancing aerobic oxidative desulfurization at room temperature.

“…However, the high cost of noble metals limits their applications. In addition, developing catalysts (e.g., metal–organic framework materials, , porphyrin, and transition-metal oxides (TMOs) , ) with low-cost and high-selectivity is critical. Among these materials, TMOs with unique electronic properties and low cost have received considerable attention and been used in ODS processes. − However, bulk TMOs, such as bulk MoO x , usually exhibit unsatisfactory catalytic activity due to the low accessibility of active sites .…”

Supported molybdenum oxide nanoparticles (MoO x NPs) have attracted intensive interest due to their unique catalytic properties. Herein, MoO x NPs anchored on graphene-analogous boron nitride (g-BN) was prepared by a simple one-step method. The interaction between supports and NPs can be enhanced, and the size of MoO x NPs can be controlled during the immobilization process. Molecular oxygen (O 2 ) in the air can be activated effectively with the as-prepared heterogeneous catalyst. It is noteworthy that experimental results indicate that the controlled MoO x NP size and strong metal oxide support interaction are the two key factors which could help to exhibit high aerobic oxidative desulfurization activity. Moreover, sulfur removal of DBT can still reach 98.0% after recycling 11 times, which indicates that the supported catalyst has a good stability and recycling performance. Finally, the Mo(IV) and Mo(V) parts serve as the active sites to promote the production of superoxide− molybdenum species and the reaction pathway is further proposed.
