Recently, significant progress has been made in developing alternative catalysts, particularly using metal-organic frameworks (MOFs) like ZIF (zeolitic imidazolate framework)-based materials. ZIF-based catalysts have shown promise in enhancing ORR activity due to their tunable structure, high surface area, and stability at low temperatures. These catalysts provide an effective solution to reducing platinum usage while maintaining or improving the efficiency of the ORR, making them a key component in developing more sustainable and cost-effective fuel cells. The application of ZIF-based cathode catalysts in low-temperature PEMFCs represents a critical advancement in the pursuit of green energy solutions, offering an avenue for improving performance while addressing cost and environmental concerns. In this study, the development of ZIF-based electrocatalyst for ORR in PEMFC applications have been reported, a ZIF-based electrocatalyst such as ZIF-8 is prepared under solvothermal condition using zinc sources (such a Zn (OAc)2·2H2O) and 2-methylimidazole (2MeIm). The prepared electrocatalyst is characterized by different surface characterization techniques which is co-related with electrochemical studies. Cyclic voltammetry was done to obtain onset potential of the prepared electrocatalyst at an optimum scan rate in basic medium. Chronoamperometry was done to study the electro-stability of the material. |
