Recently, Professor LiuYanbiao, College of Environmental Science and Engineering, DHU, and his research team made new progress in fluidic electrocatalytic ammonia synthesis. The research result, “Fluidic MXene Electrode Functionalized with Iron Single-Atoms for Selective Electrocatalytic Nitrate Transformation to Ammonia,” was published in Environmental Science & Technology, one of the top environmental journals.
Deep removal and resource utilization of nitrate in water is a hot topic in current research. Electrocatalytic nitrate reduction technology is expected to convert nitrate into high-value ammonia, which can achieve a win-win result of pollutant removal and resource utilization. Prof. Liu’s team developed a novel fluid electrocatalytic reaction system, which performed great electrocatalytic activity, ammonia selectivity, Farady efficiency and catalytic stability under complex water matrix conditions (tap water, lake water, strong acid/alkali wastewater).
