recently, the team of professor li chunzhong and associate professor li yuhang of east china university of science and technology proposed a series reaction strategy. through hydrolysis and electrolysis, adn and adipic acid (ac) can be extracted from waste pa-66 under mild conditions. ) and hydrogen (h2). the core-shell structure anode catalyst ni3s2@fe2o3 is designed with fe2o3 nanosheets on ni2s3 nanowalls to dehydrogenate c-n bonds into c≡n bonds. in the 100-hour stability test, the ni3s2@fe2o3 electrode
ma cm-2 current density (1.40 v vs.
the faradaic efficiency of adn produced under rhe is >85%. at the same time, hydrogen gas is produced at the cathode. the unique core-shell structure of ni3s2@fe2o3 enhances its electrochemical performance. x-ray photoelectron spectroscopy (xps) also shows that the formed ni(fe) oxygen (hydroxide) species may be the real active species for c-n bond dehydrogenation. this strategy provides new ideas for the sustainable production of high-value commodity chemicals and clean h2 fuel from pa-66 waste.
