| Abstract Scope |
Electrochemical energy systems, such as fuel cells and batteries, are crucial for future energy demands due to their high efficiency and low emissions. A key step in these systems is the oxygen reduction reaction (ORR), typically occurring at the cathode, which significantly influences efficiency. Developing robust and cost-effective ORR catalysts is essential since traditional Platinum-group metal (PGM)-based catalysts are expensive and degrade over time. Non-PGM catalysts, such as Nitrogen-doped graphene (N-G) and metal-organic frameworks (MOFs), have emerged as promising alternatives. Our study synthesized an advanced N-G/MOF catalyst using a Nanoscale High Energy Wet ball milling process. This catalyst showed comparable performance to the 10 wt% Pt/C catalyst and superior performance in alkaline conditions. Further enhancement was achieved by combining N-G/MOF with Ti3C2 MXene, resulting in the N-G/MOF/MXene catalyst, which demonstrated improved performance, durability, and resistance to degradation. This composite is highly efficient and durable ORR electrocatalysts for electrochemical energy applications. |
