The development of efficient and durable non-noble catalysts for alkaline hydrogen evolution is crucial. High-entropy alloys offer a promising platform, but their surface chemistry needs to be tuned for optimal performance. Conventional non-precious catalysts are typically prepared as powders and require polymeric binders and conductive additives.
