The ability of understanding the performance at a full device level is critical to rationally design new generation CO2 electrolyzer systems. In the Jiao lab, we developed a 5-electrode technique that is able to probe the resistance across different interfaces in a CO2 electrolyzer at work. With the new diagnostic tool, a record performance for CO2 electroreduction to CO was achieved. The key results were published in ACS Energy Letters. 

We recently introduce a new strategy to improve acetate selectivity in CO electrolysis. The combination of a Ni-Fe anode catalyst and a suitable anion exchange membrane enabled us to produce a highly concentrated acetate product stream with a high purity (>95%). This work represents a critical step towards commercial applications. The key results were published in Nature Catalysis. 

A joint publication with a team at University of California, Riverside was published in Nature Food. We demonstrated the feasibility to grow plants in dark using electrocatalytically CO2-derived acetate for the first time. The electrochemical-biological hybrid approach offers a completely new pathway for food production that overcomes the critical challenge associated with low efficiency in photosynthesis.

A perspective article was in JACS Au in which we discussed the emerging electrochemical technologies for decarbonizing the chemical industry.

We recently published an Account focusing on our latest contributions in both fundamental and applied research in the field of electrocatalytic CO2 and CO reduction reactions. The full article can be found in Accounts of Chemical Research.

NOx is considered as a major pollutant to our environment. We recently investigated the electrochemical approach to convert gaseous NOx using transition metal catalysts, which may help us tackle the NOx emission issues. The results have been published in JACS.

A recent study on copper-coordinated cellulose ion conductors was published in Nature. This work was conducted through collaborations among Dr. Jiao's group and other collaborators (led by Prof. Liangbing Hu at University of Maryland, College Park).
