Abstract High-efficiency hydrogen evolution is obtained from a novel fluorescein homogeneous system, comprising a noble metal free fluorescein as the photosensitizer, Pt nanoparticle as the cocatalyst and TEOA as the holes scavenger in an aqueous solution under visible light irradiation. The highest H2 production rate is 491.40 μmol/h (λ > 420 nm) and quantum efficiencies of our system are among the highest reported for the molecular hydrogen systems in the visible light range. Unlike many reported molecular hydrogen systems are either unstable under illumination and expensive, or have weak photocatalytic performances, our low-cost system exhibits excellent activity and endurance. We believe that this low-cost, high-efficiency and durable homogeneous system for molecular hydrogen may result in new breakthroughs for the hydrogen energy and solar energy utilization.

一种低成本、高效、耐用的分子氢均相系统

摘要 以不含贵金属的荧光素为光敏剂，铂纳米粒子为助催化剂，TEOA 为空穴清除剂，在可见光照射下，从一种新型荧光素均相体系中获得了高效析氢。最高的 H2 生成速率为 491.40 μmol/h（λ > 420 nm），我们系统的量子效率在可见光范围内的分子氢系统中是最高的。与许多报道的分子氢系统要么在光照下不稳定且价格昂贵，要么光催化性能较弱，我们的低成本系统表现出优异的活性和耐久性。我们相信这种低成本、
