Experimental results showed that Cu\/Al\u2013HTLCs were less stable than Co\/Al\u2013HTLCs due to the Jahn\u2013Teller effect. However, electrocatalytic activity of copper was superior to that of cobalt; thus, Cu\/Co\/Al\u2013HTLCs were selected based on their stable crystalline structure and electrochemical activity. The optimized Cu2CoAl\u2013HTLC was highly active in nitrate reduction, with two peaks for nitrate and nitrite reduction, respectively. Ammonia, nitrite and N-containing gases were found to be the final products of constant potential electrolysis at \u22120.54 and \u22120.74 V.<\/jats:p>","DOI":"10.3390\/nano10101926","type":"journal-article","created":{"date-parts":[[2020,9,27]],"date-time":"2020-09-27T22:24:42Z","timestamp":1601245482000},"page":"1926","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Characterization and Electrochemical Behaviour of Nanoscale Hydrotalcite-Like Compounds toward the Reduction of Nitrate"],"prefix":"10.3390","volume":"10","author":[{"given":"Liang","family":"Li","sequence":"first","affiliation":[{"name":"School of Environment and Architecture, University of Shanghai for Science and Technology, Shanghai 200093, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junhao","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Environment and Architecture, University of Shanghai for Science and Technology, Shanghai 200093, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yafeng","family":"Yun","sequence":"additional","affiliation":[{"name":"School of Environment and Architecture, University of Shanghai for Science and Technology, Shanghai 200093, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shouxun","family":"Hu","sequence":"additional","affiliation":[{"name":"School of Environment and Architecture, University of Shanghai for Science and Technology, Shanghai 200093, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8423-3252","authenticated-orcid":false,"given":"Yuanxing","family":"Huang","sequence":"additional","affiliation":[{"name":"School of Environment and Architecture, University of Shanghai for Science and Technology, Shanghai 200093, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,9,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"107","DOI":"10.1016\/j.toxlet.2010.11.002","article-title":"Vegetable-borne nitrate and nitrite and the risk of methaemoglobinaemia","volume":"200","author":"Chan","year":"2011","journal-title":"Toxicol.
