Mukherjee, Biswanath published the artcileSolvothermally Synthesized Iron Phthalocyanine Nanostructure for High ORR Response: A Joint Experimental Investigation and DFT Analysis, Name: Phthalonitrile, the main research area is synthesized iron phthalocyanine nanostructure ORR DFT electrochem.
In search for replacement of expensive, rare Pt based electrocatalyst towards O reduction reaction (ORR), transition metal-cored phthalocyanine (MPc) were under current research focus. Among various MPc, Fe phthalocyanine (FePc) gives best ORR performance, presumably because of its strong electron withdrawing capability. Herein, the authors report one pot solvothermal synthesis of 1 Dimensional FePc nanostructure and its possible application as ORR catalyst. The ORR performance of FePc nanostructure was carried out in 0.1M KOH (pH = 13) via cyclic voltammetry and linear sweep voltammetry. The performance, which was comparable with com. available Pt/C, measures a half wave potential (E1/2 = 0.64 V vs. RHE), onset potential (Eonset = 0.87 V vs. RHE) and electron transfer number (n) of 3.9 at 0.35 V (vs. RHE), indicating that the synthesized nanostructure essentially promote 4-electron reduction pathway. Addnl., unlike Pt/C, the synthesized nanostructure showed good MeOH tolerance. To elucidate the ORR performance from FePc, 1st principle based DFT calculation on two dimensional FePc monolayer was carried out and presented here for deeper insight. The excellent ORR activity coupled with MeOH tolerance favors the FePc nanostructure as a promising alternative to conventional Pt-based electrocatalyst for future energy storage and fuel cells.
