Atomically Dispersed Platinum Catalysts for Efficient Hydrogen Production

Abstract

As the world shifts from fossil fuel-based energy industries to renewable energy industries in response to climate change caused by greenhouse gases, producing green hydrogen from water offers a solution that not only avoids greenhouse gas emissions but also serves as a clean energy carrier central to the hydrogen industry chain. However, Current hydrogen production methods are limited by low efficiency and cost-effectiveness, requiring further technological advancements. This study focuses on developing atomically dispersed platinum catalysts that enhance catalytic activity while minimizing the use of platinum in hydrogen production reactions. Compared to conventional platinum nanoparticle catalysts, the hydrogen production efficiency per unit mass of platinum increased by over 30 times, and the catalyst's long-term durability was also confirmed. Additionally, the characteristics of the highly dispersed platinum catalyst were analyzed to identify the active sites.
