Abstract

Inventia se refera la electrochimia tehnica, si anume la electrodul pentru obtinerea electroliticaa hidrogenului si la procedeul de confectionare aacestuia. Electrodul, conform inventiei, consta dintr-un suport conducator de curent din material fibrocarbonic poros si dintr-un strat activ din aliaj poros de cobalt-nichel-bor-paladiu. Procedeul de confectionare a electrodului include depunerea pe suportul conducator de curent a aliajului poros de cobalt-nichel dintr-o solutie, care contine saruri de cobalt, de nichel si dimetilaminoboran, cu dizolvarea ulterioara a componentului nemetalic. Se efectueaza activarea catalitica cu paladiu a suprafetei poroase a materialului fibrocarbonic si depunerea chimico-catalitica a aliajului de cobalt-nichel-paladiu-bor din solutie, care suplimentar contine sare de paladiu, pirofosfat de potasiu, trietanolamina si 2-mercaptobenzotiazol, in urmatorulraport al componentelor, g/L: clorura de nichel 30…35sulfat de cobalt 15…20clorura de paladiu 3…5pirofosfat de potasiu 60…80solutie apoasa de 25% de trietanolamina, mL 60…100dimetilaminoboran 1…32-mercaptobenzotiazol 0,01…0,02.Depunerea aliajului se efectueaza la temperatura de 50…70°C si pH 6,5…10,0, iar dizolvarea se efectueaza prin prelucrarea in fluxul unei solutii incalzite pana la 40…50°C, timp de 3…5 min, solutia avand urmatorul raport al componentelor, g/L:persulfat de amoniu 20…50acid sulfuric, densitatea 1,84 10…15apa restul. The invention relates to the technical electrochemistry, namely to the electrode for obtaining electrolytic hydrogen and to the process of making it. The electrode, according to the invention, consists of a current conducting support of porous fibrocarbon material and an active layer of porous cobalt-nickel-boron-palladium alloy. The process of making the electrode includes the deposition on the current conducting support of the cobalt-nickel porous alloy in a solution, which contains cobalt, nickel and dimethylaminoboran salts, with the subsequent dissolution of the non-metallic component. Palladium catalytic activation of the porous surface of the fibrocarbon material and the chemical-catalytic deposition of cobalt-nickel-palladium-boron alloy in the solution is carried out, which additionally contains palladium salt, potassium pyrophosphate, triethanolamine and 2-mercaptobenzothiazole, in the following report of components, g / L: nickel chloride 30 ... 35 cobalt sulphate 15 ... 20 palladium chloride 3 ... 5 potassium pyrophosphate 60 ... 80 25% aqueous triethanolamine solution, mL 60 ... 100 dimethylaminoborane 1 ... 32-mercaptobenzothiazole 0.01 ... 0.02 . The alloy is deposited at 50 ... 70 ° C and pH 6.5 ... 10.0, and the dissolution is carried out by processing in the flow of a heated solution up to 40 ... 50 ° C, for 3 ... 5 minutes, the solution having the following component ratio, g / L: ammonium persulfate 20 ... 50 sulfuric acid, density 1.84 10 ... 15 after the remainder.
