The main challenge of commercialization of the hydrogen economy is the lack of convenient and safe hydrogen storage materials, which can adsorb and release a significant amount of hydrogen at ambient conditions. Finding and designing suitable cost-effective materials are vital requirements to overcome the drawbacks of investigated materials. Because of its outstanding electronic, thermal, and chemical properties, the electrically conducting polyaniline (PANI) has a high potential in hydrogen storage applications. In this review, the progress in the use of different structures of conducting PANI, its nanocomposites as well as activated porous materials based on PANI as hydrogen storage materials is presented and discussed. The effect of the unique electronic properties based on the π-electron system in the backbone of these materials in view of the hydrogen uptake and the relevant mechanisms are highlighted.
氢能经济商业化的主要挑战是缺乏方便、安全的储氢材料，这些材料可以在环境条件下吸附和释放大量氢气。寻找和设计合适的具有成本效益的材料是克服所研究材料缺点的关键要求。由于其出色的电子、热和化学性质，导电聚苯胺（PANI）在储氢应用中具有很高的潜力。在本文综述中，介绍并讨论了不同结构的导电 PANI、其纳米复合材料以及基于 PANI 的多孔活性材料作为储氢材料的研究进展。强调了这些材料骨架中π电子体系的独特电子性质对吸氢的影响及其相关机制。
