New technique to probe voltage losses
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.

Enhancing acetate production in CO electrolysis
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.

Converting CO2 into food
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.

Electrochemical conversion of NOx
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.

Ion conductor for solid-state batteries
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).
