Pt(0)-Based Catalyst Supported on Silica Containing Di(ethylene oxide) Units for Hydrosilylation of Unsaturated Carbon−Carbon Bonds

Polyaniline/carbon black composite as Pt electrocatalyst supports for methanol oxidation: Synthesis and characterization

“…The peaks at 39.9°, 46.5°, 67.8°, 81.2°, 85.8° correspond to [111], [200], [220], [311], [222] crystal planes of Pt 41. According to the measurement of the width of the strongest peak (Pt[111]) at half of its height the size of Pt grains can be calculated by the Scherrer formula42: B (2θ) = 0.94λ/ L cos θ. B (2θ) is half‐peak width, λ is the incident wavelength (0.1542 nm), L is the particle radius, and θ is the diffraction angle.…”

Tethered ansa-bridged titanium complexes immobilized on 3-mercaptopropyl-functionalized silica gel and their application for the hydrosilylation of imines

“…However, only few studies 5,6 have been reported in the area of hydrosilylation with supported catalysts, including the hydrosilylation of ketones with Rh-based catalysts supported either on organic polymeric matrices 6 or silica, 7,8 and the heterogeneous hydrosilylation of alkenes with Rh- 9,10 and Pt-based catalysts. [11][12][13] In addition, titanocene complexes are known to be highly active and selective catalysts for hydrosilylations. 4,[14][15][16][17] However, supported Ti-based catalysts have been mainly used for polymerizations, [18][19][20][21][22] epoxidations, [23][24][25][26] oxidations, 24,27 and hydrogenations, 28 as well as anticancer drugs.…”

Synthesis of a novel functional polymer immobilized platinum complex and its application in the catalytic hydrosilylation of 3,3,3-trifluoropropene with triethoxysilane

“…To this end, many research groups have focused on heterogeneous catalysts for hydrosilylation, and have reached many interesting conclusions [15,16]. Some organic polymer immobilized platinum catalysts have been used to catalyze the hydrosilylation, which showed excellent catalytic performance for specific substrates [17][18][19][20].…”
