Mukherjee, Jit published the artcileUnderstanding the Site-Selective Electrocatalytic Co-Reduction Mechanism for Green Urea Synthesis Using Copper Phthalocyanine Nanotubes, HPLC of Formula: 91-15-6, the main research area is copper phthalocyanine nanotube electroccatalytic coredn green urea preparation.
Green synthesis of urea under ambient conditions by electrochem. co-reduction of N2 and CO2 gases using effective electrocatalyst essentially pushes the conventional two steps (N2 + H2 = NH3 and NH3 + CO2 = CO(NH2)2) industrial process at high temperature and high pressure, to the brink. The single step electrochem. green urea synthesis process has hit a roadblock due to the lack of efficient and economically viable electrocatalyst with multiple active sites for dual reduction of N2 and CO2 gas mols. to urea. Herein, copper phthalocyanine nanotubes (CuPc NTs) having multiple active sites (such as metal center, Pyrrolic-N3, Pyrrolic-N2, and Pyridinic-N1) as an efficient electrocatalyst which exhibits urea yield of 143.47μg h-1 mg-1cat and faradaic efficiency of 12.99% at -0.6 V vs. reversible hydrogen electrode by co-reduction of N2 and CO2 are reported. Theor. calculation suggests that Pyridinic-N1 and Cu centers are responsible to form CN bonds for urea by co-reduction of N2 to NN* and CO2 to *CO, resp. This study provides the new mechanistic insight about the successful electro-reduction of dual gases (N2 and CO2) in a single mol. as well as rational design of efficient noble metal-free electrocatalyst for the synthesis of green urea.
