摘要： The disclosure relates to methods of forming a dihydrochalcone using electrocatalytic dehydrogenation. In particular, the disclosure relates to methods of forming a dihydrochalcone electrocatalytically hydrogenating (ECH) a reactant compound over a catalytic cathode in a reaction medium having a non-alkaline pH value, thereby forming a dihydrochalcone product; wherein the reactant compound has a structure according to Formula (I). The method can be used to prepare dihydrochalcone sweeteners, such as, for example, naringin dihydrochalcone and neohesperidin dihydrochalcone.

摘要： An abrupt interface electroreduction catalyst includes a porous gas diffusion layer and a catalyst layer providing a sharp reaction interface. The electroreduction catalyst can be used for converting CO2 into a target product such as ethylene. The porous gas diffusion layer can be hydrophobic and configured for contacting gas-phase CO2 while the catalyst layer is disposed on and covers a reaction interface side of the porous gas diffusion layer. The catalyst layer has another side contacting an electrolyte and can be hydrophilic, composed a metal such as Cu and is sufficiently thin to prevent diffusion limitations of the reactant in the electrolyte and enhance selectivity for the target product. The electroreduction catalyst can be made by vapor deposition methods and can be used for electrochemical production of ethylene in reaction system.

摘要： This invention relates to a process for the electrochemical synthesis of green urea, and the urea produced thereby. The electrochemical synthesis of urea involves the reduction of dual purging gases N2 and CO2 via six electron transfer process (N2+CO2+6H++6e−→CO (NH2)2+H2O) & reduction of the NO3− ions and CO2 via sixteen electron transfer process (2NO3−+CO2+18H++16e−→CO(NH2)2+7H2O) under ambient condition using copper phthalocyanine (CuPc) catalyst. The binding of two intermediate products during dual reduction simultaneously, leads to the production of urea in water medium under ambient conditions.

摘要： A method for preparing products by electrochemical reductive amination and simultaneous oxidation of aldehyde-based biomass using non-precious metal catalysts is provided, which relates to a field of electrocatalysis. The preparing method includes: performing an electrochemical reaction in an electrolytic system with room temperature and atmospheric pressure (at a range of 25° C. to 30° C., 101 kPa) by taking an aldehyde compound and an amine compound as raw materials for reductive amination and oxidation of aldehyde-based biomass, and thereby obtaining the products. The electrolytic system includes a reaction substrate, an electrolyte, a solvent, an anode and a cathode. The anode is a phosphorylated hydrotalcite catalyst and the cathode is a Ti-based catalyst. The method uses no external oxidants and precious metal catalysts, which is clean, environmental and efficient.
