The synthesis, physicochemical characteristics, and operation of the previously proposed new multifunctional polymetallic catalysts in reduction processes are considered. The complex intermetallides...

Supported polymetallic catalysts (5–15% wt% of active phase) for deep oxidation and hydrogenation were successfully prepared by Self-propagating Surface Synthesis (SSS) using metal nitrates as...

Prerequisites for the use of photodynamic therapy (PDT) to treatment of atherosclerosis, as well as the development and structure of atherosclerotic vascular lesions in humans are analyzed. The basic requirements for PDT components, specifically photosensitizers (PS), and the radiation source, and the current state of their development are overviewed. Some original results of in vitro studies of the effect of PS on the basis of phthalocyanines and radiation on cells from the atherosclerotic plaques are presented.

Supported mono- and bimetallic catalysts containing 10 wt % Ni(I), 10 wt % Co(II), and 5 wt % Co + 5 wt % Ni(III) on halloysite nanotubes have been synthesized by low-temperature combustion in porous media. The catalyst samples have been studied by XRD analysis, SEM, electron probe microanalysis, and TPR; specific surface area has been determined by the BET method according to the physical adsorption of nitrogen. The activity and selectivity of the synthesized catalysts have been studied using the example of the deep oxidation of CO and propane and the hydrogenation of CO₂ at atmospheric pressure. It has been found that the highest activity in the deep oxidation of CO and propane is exhibited by the Co-containing samples, particularly the bimetallic Co–Ni catalyst. In the case of CO₂ methanation in the presence of the freshly synthesized samples, the activity can be arranged in the following order: I > III > II. The reduction of the catalysts in a hydrogen stream at 400°С for 1 h has led to a significant increase in their activity with a maximum at 350°С, while the order of activity has remained unchanged. In the presence of reduced sample I, a CO₂ conversion of 88.8% at a methane selectivity of 97.7% has been achieved.

A new class of highly active polymetallic catalysts for deep oxidation based on iron with admixtures of other d-metals and rare earths has been developed. The precursors of the catalysts are...
