摘要： An electrocatalyst for use in electrolytic reduction of carbon dioxide gas in an aqueous solution. The electrocatalyst is formed of nickel alkyl cyclam which is expressed by the general formula: ##STR1## where each of R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 is selected from the group consisting of hydrogen atom and aliphatic saturated hydrocarbon group expressed by the formula of C.sub.n H.sub.2n+1 ; wherein at least one of R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 is the aliphatic saturated hydrocarbon group in which n is a number ranging from 1 to 22. The nickel alkyl cyclam as the electrocatalyst is excellent in stability and energy consumption improving effect while exhibiting a high carbon dioxide gas reduction effect, as compared with conventional nickel cyclam.
