“…Although Rayati's group achieved the epoxidation of styrene, sacrificial agents were needed and the selectivity was also low (67%). 7 Compared with that, our catalytic system was far superior. Then, the kind of photocatalyst was optimized (Table 1, entries 1 to 7), revealing that Fe@POG-OH exhibited an excellent photocatalytic performance for the oxidation of styrene in 8 h. The results show that POG-OH also has photocatalytic activity.…”

“…Styrene epoxide belongs to an important class of compounds that are useful in the synthesis of a wide range of materials, including epoxy resins, perfumes and fine chemicals. 1 Many works have recently reported on styrene oxidation, [2][3][4][5][6][7] such as that over heterogeneous cobalt, 8 manganese, 9 gold, 10 titanium, 11,12 silver, 13,14 iron, 15,16 palladium, 17 copper, 18 and ruthenium. 19 However, most of these catalytic systems mainly contain metalloporphyrin derivatives imitating cytochrome P450 enzymes and these catalytic systems require high temperature, high O 2 pressure, or the addition of a noble metal cocatalyst or sacrificial agent.…”

in order to make full use of the impact of internal and external factors on the performance of title catalyst for ethyl benzene oxidation, the key internal influencing factors on the catalytic performance were modulated by coordinating and grafting manganese porphyrin to mesoporous and macroporous chitosan, and the important external factors (i.e. oxidation reaction conditions) were optimized using Response Surface Methodology. Under the Response Surface Methodology optimized oxidation reaction conditions (176.56 °C, 0.59 MPa, and 0.25 mg amount of manganese porphyrin), the catalyst could be used at least five times. The ethyl benzene conversion, catalyst turnover numbers, and yields reached up to 51.2%, 4.37 × 10 6 and 36.4% in average, respectively. Compared with the other optimized oxidation reaction conditions, the corresponding values increased 17%, 26% and 53%. Relative to the manganese porphyrin, the catalytic performance and efficiency of the immobilized catalyst had notably increased. High-efficiency and high-selectivity oxidation of ethyl benzene (EB) has been still paid a great attention 1-6. There were so many advanced catalysts and catalytic ethyl benzene oxidation technologies 1-25 , some of which could even offer high yields of products 1-6. 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). Because RSM has been successfully used in other catalysis fields: It has been used for optimization of the various reaction conditions and prediction of interactions between the influencing reaction condition parameters based on constructing a suitable model, evaluating the effects of key factors and searching the optimum reaction conditions. The better catalysis responses have achieved 26-29. These considerations and the various optimizations above will probably bring the advanced catalysis techniques 7-25 forwards better catalytic results and excellent various applications in practical chemistry industry. Due to a great deal of attention to the environmental issues, for modern companies which are manufacturing the products of acetophenone and phenylethanol via ethyl benzene oxidation, a set of strict modern technique of cleaner production has to be requested. Under the preconditions, the immobilized metalloporphyrins and their catalysis systems, which are usually not added any additives, co-reductants, and solvents, but oxygen molecules...

“…To address these issues, the strategy of heterogenization of homogeneous catalytically active moieties over an inorganic solid support has been employed by different scientific communities. This has been accomplished by immobilizing these catalytically active moieties over a variety of solid support materials such as cSiO 2 , multiwalled carbon nanotubes, graphene oxide (GO), metal–organic frameworks, SBA-15, Fe 3 O 4 @SiO 2 , and so on. Among these, graphene/GO-derived nanocomposites have been come out as new star materials in the nanomaterial assisted catalysis. , …”

In this study, 1-(3-aminopropyl)imidazole-functionalized porous graphene oxide nanosheets (GONs) decorated with palladium nanoparticles (Pd NPs; size, ∼11 nm) have been developed. This has been accomplished via covalent immobilization of amine-terminated imidazolium moieties over GONs, which were further decorated with Pd NPs by employing chemical reduction method. To authenticate the successful preparation of a nanocatalyst (i.e., GO-Imd-Pd), numerous physicochemical characterization techniques, such as FT-IR, XRD, TEM, TGA, SEM, EDAX, XPS, CHN, ICP-MS, and BET surface area analysis, have been utilized. The synthesized hybrid nanomaterial could validate its supremacy as a highly efficacious and heterogeneous nanocatalyst for the oxidative amidation of aldehydes. The prepared hybrid nanomaterial could offer Lewis acidic sites, which could help in the activation of reactant molecules, thereby delivering a high yield of the product. The prepared hybrid nanomaterial could be effortlessly separated from the reaction mixture by simple centrifugation technique. Also, the prepared nanocatalyst showed magnificent recyclability up to six catalytic runs without any perceptible loss in its activity and showed no sign of disintegration.
