Electrocatalytic ethylbenzene valorization using a polyoxometalate@covalent triazine framework with water as the oxygen source

Abstract

Ethylbenzene (EB) oxidation is an important transformation in chemical industry. Herein, PMo10V2@CTF, a noble metal free electrocatalyst, was used to promote the oxidative upgrading of EB. Under ambient conditions, 65%...

Indirect Electrocatalysis S─N/S─S Bond Construction by Robust Polyoxometalate Based Foams

“…It is worth noting that the sulfenamides rubber vulcanization accelerators in solid phase and H 2 in gas phase in the indirect electrocatalytic systems can be readily separated and collected, resulting in simultaneous generation of varied value‐added products in a single system. [ 44,49 ] This powerful system that can simultaneous production of value‐added chemical products and H 2 hold much potential in practical industrial applications.…”

“…It is worth noting that the sulfenamides rubber vulcanization accelerators in solid phase and H 2 in gas phase in the indirect electrocatalytic systems can be readily separated and collected, resulting in simultaneous generation of varied value-added products in a single system. [44,49] This powerful system that can simultaneous production of value-added chemical products and H 2 hold much potential in practical dustrial applications. Furthermore, in order to further explore the properties of the sulfenamides rubber additives, we have successfully applied thus-obtained sulfenamides rubber additives (1c and 2c) in the rubber vulcanization industry applications (Figure S23a-d, Supporting Information).…”

“…[36][37][38][39][40] Importantly, POMs as kind of emerging molecular redox electrocatalysts could undergo fast and reversible stepwise electron transfer in the electrochemical reaction, holding much promise as green electrocatalysts. [41][42][43][44] Recently, there are some cases of POMs based electrocatalysts (e.g., [Co III W 12 O 40 ] 5− , [Co 4 (H 2 O) 2 (PW 9 O 34 ) 2 ] 10− , Ru-POMs, etc.) for the oxygen reduction/evolution, [45] electrocatalytic hydroxylation of arenes, [46] oxidation of ethanol/methanol, [47] etc.…”

Electrocatalytic water oxidation enabling the highly selective oxidation of styrene to benzaldehyde

“…or small molecules (H 2 O, O 2 , etc.). [17][18][19][20][21] For instance, Sargent et al 17 reported Cl À -mediated oxidation of ethylene to ethylene oxide with high selectivity, which achieved a current density of 1 A cm À2 and a faradaic efficiency of B70%. Qian et al 18 demonstrated that bromine and oxygen redox species promote the highly selective electro-epoxidation of ST. With this advance as an inspiration, the electrooxidation of ST to form BzH might be realized by utilizing a reaction mediated by reactive oxygen species (ROS).…”

Polyoxometalate–Ionic Liquid-Catalyzed Ritter Reaction for Efficient Synthesis of Amides

“…Polyoxometalates, as typical Brønsted acids, have also been applied in the Ritter reaction. [16][17][18][19] For instance, Firouzabadi et al showed that H 3 PW 12 O 40 can efficiently catalyze the amidation of various alcohols with nitriles under reflux conditions. 17 However, for the reaction of solid nitriles, additional sodium dodecyl sulfate was required.…”
