Abstract Minimizing the use of platinum (Pt) in proton exchange membrane fuel cells (PEMFCs) is crucial for expanding PEMFC market. The most straightforward approach would be to reduce size Pt particles. However, small clusters, particularly those <2 nm size, typically exhibit reduced activity oxygen reduction reaction (ORR) due overly strong adsorption intermediates. Additionally, these clusters tend degrade more quickly, resulting lower durability. In this study, carbon‐embedded alloy...
Developing highly active and durable catalysts with minimal platinum (Pt) usage is crucial for reducing the overall cost of proton exchange membrane fuel cells (PEMFCs). Herein, we introduce a scalable synthesis carbon-bound using upcycling polystyrene (PS) polymer. Our approach utilizes solvent-based hyper-cross-linking techniques to spontaneously achieve hierarchically porous structure in single-step process. The Pt-loaded PS-derived carbon support features mesopore that enhances mass...
