The article describes the results of experimental studies on the development of new active electrocatalysts for their use in the electrodes of the membrane-electrode block of a solid-oxide hydrogen-air fuel cell. Since the composition of the synthesized catalysts has a significant effect on its electrokinetic activity (electrical conductivity), the synthesis of nanoscale bimetallic catalysts of various qualitative and quantitative compositions is carried out. The choice of metal for the synthesis of the catalyst was determined by its electronic structure. The electrocatalytic activity of the developed catalysts was evaluated by studying the activity of the catalysts with respect to the decomposition of hydrogen peroxide. The developed bimetallic PVPD-Pt/ZnO/C catalysts exhibit activity with respect to the decomposition of hydrogen peroxide at 40–50 °C.

At present, when the whole world is intensively switching to organic farming, the refusal or minimization of the usage of chemical plant protection products and synthesized fertilizers is a very urgent issue of the agro-industrial complex (AIC). Accordingly, the solution to the problems of increasing yields and ensuring the fight against pathogenic components should be carried out in accordance with the principles of "green" chemistry. In this regard, usage of mixed-ligand complexes based on carboxylic and amino acids with biogenic metals is dictated not only by their availability, low cost, and the ability to increase crop yields, but also by fungicidal activity, less toxicity, easily biodegradability, which lists them among the "green" ones and cost-effective plant biostimulants. In the present work, mixed ligand complex based on succinic acid, glycine and copper with the formula [Cu(succ)(gly)]n, was developed for usage as a fungicidal biostimulant, which has the ability to significantly reduce the number of pathogens. We have found that this compound has a layered structure and can increase soybean germination up to 100%.
