| Popis: | New platinum nanocomposites were synthesized by chemical reduction of H2PtCl6•6H2O in situ with a methanol—water mixture using mesoporous carbon nitride as a stabilizing matrix and a catalyst support. The textural, morphological, and optical properties and the structural and phase composition of the composites were studied by low-temperature nitrogen adsorption—desorption, scanning electron microscopy, photoluminescence, IR, and UV spectroscopy, powder X-ray diffraction, and inductively coupled plasma atomic emission spectrometry. The introduction of metal particles did not induce significant changes in the structural integrity and, hence, in the specific physicochemical properties of mesoporous carbon nitride. The catalytic activity of the synthesized nanocomposites was evaluated in the hydrogenation of phenylacetylene, styrene, and cyclohexene. |
