C-O Hydrogenolysis of C3-C4 Polyols Selectively to Terminal Diols over Pt/W/SBA-15 Catalysts

Susmita Bhowmik et al.

Summary: Pt/W/SBA-15 catalysts prepared by the sequential impregnation method were evaluated for selective C-O cleavage of erythritol and glycerol in an aqueous medium. The catalysts showed synergistic enhancement in C-O hydrogenolysis activity/selectivity at higher Pt loadings, resulting in high yields of terminal diols.

Synthesis of g-C3N4/W-SBA-15 Composites for Photocatalytic Degradation of Tetracycline Hydrochloride

Yongzheng Duan et al.

Summary: The addition of g-C3N4 to W-SBA-15 was found to significantly improve the photocatalytic degradation properties, with the g-C3N4(3.0)/W-SBA-15 exhibiting the highest catalytic activity, nearly 4.3 times greater than that of W-SBA-15. The enhanced photocatalytic activity of g-C3N4/W-SBA-15 is attributed to the formation of heterojunction between g-C3N4 and tungsten species, leading to effective separation of photo-generated charge carriers and increased absorption of visible light.

Epoxidation of 1,5,9-cyclododecatriene with hydrogen peroxide under phase-transfer catalysis conditions: influence of selected parameters on the course of epoxidation

Grzegorz Lewandowski et al.

Summary: This study investigates the epoxidation of 1,5,9-cyclododecatriene using hydrogen peroxide as the oxidizing agent under phase transfer catalysis conditions. The highest yield of 1,2-epoxy-5,9-cyclododecadiene is achieved at 54.9 mol% with the conversion of CDT reaching 72.3 mol%. Further research is needed to develop a more efficient and environmentally friendly method for obtaining this compound.
