储氢材料抗杂质气体毒化策略研究进展

Progress in Strategies Against the Impurity Gas Poisoning of Hydrogen Storage Materials

杂质气体毒化导致储氢材料循环性能衰减的关键因素之一。由于在实际应用中高纯度氢气源的处理难度和成本问题,氢气中不可避免存在一定的杂质气体,从而造成储氢材料毒化。提高储氢材料的抗毒化能力,对储氢材料的工程化应用具有重要意义。本文从表面改性和表界面调控两方面对抗毒化策略进行总结,并对储氢材料抗杂质气体毒化方法研究方向进行了展望。

Impurity gas poisoning is one of the key factors leading to the degradation of the cyclic performance of hydrogen storage materials. Due to the difficulty and high cost of producing high-purity hydrogen sources, the presence of impurity gases in hydrogen resources is inevitable, which could poison the surface of hydrogen storage materials. Improving the ability of anti-poisoning is of great significance for the practical application of hydrogen storage materials. This work summarises the anti-poisoning methods in terms of surface modification and surface-interface control, and gives a prospective on the future research direction of the anti-poisoning methods for hydrogen storage materials.
