Hybridizing strategy of decatungstate by Au nanoparticles for enhanced photo-catalytic oxidation of hydrocarbons by dioxygens

Engineering the heterogeneous photocatalytic activity of crystalline decatungstate-based coordination polymers

“…In addition, both TBADT in acetonitrile and NaDT in aqueous solution are homogeneous systems, which face problems of recycling and separation of the catalyst from the product, limiting their application. Thus, improving DT-based photocatalysts by increasing its light harvesting efficiency 14 and reducing its leaching are helpful for the extension of their application in more media. 15…”

“…In addition, both TBADT in acetonitrile and NaDT in aqueous solution are homogeneous systems, which face problems of recycling and separation of the catalyst from the product, limiting their application. Thus, improving DT-based photocatalysts by increasing its light harvesting efficiency 14 and reducing its leaching are helpful for the extension of their application in more media. 15 Through computational studies, Waele et al have revealed the mechanism of the photocatalytic HAT reaction catalyzed by the DT catalyst, which involves the charge transfer process from terminal oxygen atoms binded with "polar terminal" tungsten atoms (O p,t , see Fig.…”

In situ-synthesized Co and N-doped mesoporous hollow silica spheres for the selective oxidation of ethylbenzene

“…The global demand for acetophenone is increasing as it is an important intermediate in the production of fine chemicals. 1,2 Traditional industrial methods for the production of acetophenone include Friedel-Crafts acylation, phenylacetic acid decomposition and selective oxidation of ethylbenzene. The Friedel-Crafts acylation reaction produces environmentally harmful by-products and the recovery of the catalyst becomes difficult.…”

“…Noble metal-based catalysts, nonprecious metal-based catalysts and metal-free catalysts have all been investigated for the selective oxidation of ethylbenzene to prepare acetophenone. 2,7,[10][11][12][13][14] Metal-free based catalysts are inexpensive and show good cycling performance, but they usually exhibit relatively poor catalytic performance. Although noblemetal-based catalysts have shown excellent catalytic performance in the oxidation of ethylbenzene, the high cost and scarce resources considerably limit their large-scale industrial applications.…”
