氢气是一种极具吸引力的未来能源。开发氢载体，没有任何安全风险，即，高压和毒性，是一个紧迫的问题。在此，我们提出了作为氢载体的芴酮/芴醇聚合物片材，其具有高安全性、可模塑性和易于处理性。与其他氢载体所需的条件相比，铱催化剂允许聚合物片在更温和的条件下（< 100 °C和环境压力）固定和释放氢气。用少量水（包括铱络合物催化剂）溶胀的聚合物片材在25 °C和环境氢气压力下氢化，通过化学键形成储存氢气，然后当简单地升温至95 °C时在5小时内释放氢气。
Hydrogen is an attractive future energy source. Developing a hydrogen carrier, without any safety risk, i.e., high pressure and toxicity, is an urgent issue. Herein we present a fluorenone/fluorenol polymer sheet as a hydrogen carrier featuring high safety, moldability, and ease of handling. An iridium catalyst allows the polymer sheet to fix and release hydrogen gas under milder conditions (< 100 °C and ambient pressure), compared to those required by other hydrogen carriers. The polymer sheet, swollen with a small amount of water including the iridium complex catalyst, was hydrogenated at 25 °C and ambient hydrogen pressure, stored hydrogen via chemical bond formation, and then released it within 5 h when simply being warmed to 95 °C.
