Highly selective oxidation of benzyl alcohol to benzaldehyde with hydrogen peroxide by cobalt aluminate catalysis: A comparison of conventional and microwave methods

Heteropoly Tungstate Supported on Metal Oxide Catalysts for Liquid Phase Oxidation of Benzyl Alcohol with Hydrogen Peroxide

“…598 and 516 cm -1 may be attributed to symmetric vibrations of O-P-O and W-O-W, respectively. 33 Regardless of minor variations in intensities of characteristic bands responsible for the PW polyanions, their presence in all supported HPW/CeO 2 catalysts confirm that Keggin structure remains intact upon supporting varied (Figure 2b). 26,39 However, these characteristic features were invisible in various supported xHPW/CeO 2 (x = 15, 20, and 25 wt.%) composite materials (Figures 2c-2e).…”

Eletrodos de feltro de carbono modificados com filme dimérico de rutênio: aplicação em oxidações eletroquímicas de álcoois

“…Oxidação seletiva de álcoois à aldeídos é de grande importância na química sintética [10,14]; os processos eletrocatalíticos apresentam, geralmente, melhores seletividade e eficiência quando comparados com outros métodos de oxidação [20][21][22][23][24].…”

Comparative Catalytic Evaluation of Nano-ZrOx Promoted Manganese Catalysts: Kinetic Study and the Effect of Dopant on the Aerobic Oxidation of Secondary Alcohols

“…No formation of acetophenone was observed in this case which indicates that the prepared catalyst plays a fundamental role in the aerial oxidation of 1-phenylethanol. In order to recognize the performance of the catalyst in comparison to the previously reported studies, a list of reported catalysts has been compiled as shown in Table 5, which demonstrates the results of 1-phenylethanol oxidation by molecular O 2 in the presence of various catalysts [3,8,9,15,36,52,[67][68][69][70][71][72][73][74][75][76][77][78][79][80]82]. It was found that the prepared 1% ZrO x -MnCO 3 catalyst is the utmost effective catalyst among all the mentioned catalysts.…”

“…Furthermore, there are many oxidation catalysts prepared by employing noble metals, such as gold [16][17][18][19][20][21], palladium [22][23][24][25], platinum [26,27], rhodium [28,29], and ruthenium [30,31], which have been extensively utilized for the aerial oxidation of alcohols with high catalytic performances. Consequently, a significant effort has been made in order to explore eco-friendly and low cost catalysts 2 Advances in Materials Science and Engineering such as nonnoble metals like copper [32][33][34], cobalt [35][36][37], nickel [38][39][40], iron [41,42], vanadium [43], silver [44], chromium [45,46], molybdenum [47,48], rhenium [49], and zinc [50][51][52] for aerobic oxidation of alcohols. In addition, it has been extensively reported that the catalytic activity of mixed metal oxide nanoparticles catalysts enhanced remarkably upon doping with other metals probably due to the extremely high surface area of metal nanoparticles [53,54].…”
