摘要: In this research, nano Cu/Al–HTLCs, Co/Al–HTLCs and Cu/Co/Al–HTLCs were synthesized, characterized, tested in electrolytic reduction nitrate. Experimental results showed that Cu/Al–HTLCs less stable than due to the Jahn–Teller effect. However, electrocatalytic activity of copper was superior cobalt; thus, selected based on their crystalline structure electrochemical activity. The optimized Cu2CoAl–HTLC highly active nitrate reduction, with two peaks for nitrite respectively. Ammonia, N-containing gases found be final products constant potential electrolysis at −0.54 −0.74 V.
