Exploitation of solid-state proton-conducting materials with high anhydrous proton conductivity from subzero temperature (<273 K) to moderate temperature (>353 K) is a great challenge. Here, Brönsted acid-dopped zirconium-organic xerogels (Zr/BTC-xerogels) are prepared for anhydrous proton conduction from subzero to moderate temperature. Abundant acid sites and strong H-bonding interactions make the CFSOH (TMSA)-introduced xerogel gain high proton conductivity from 9.0 × 10 S cm (253 K) to 1.40 × 10 S cm (363 K) under anhydrous conditions, which are in the leading level. This provides a new possibility to develop wide-operating-temperature conductors.
开发在从零下温度（<273 K）到中等温度（>353 K）范围内具有高无水质子传导率的固态质子传导材料是一项巨大挑战。在此，制备了布朗斯特酸掺杂的锆有机干凝胶（Zr/BTC-干凝胶）用于从零下温度到中等温度的无水质子传导。丰富的酸性位点和强大的氢键相互作用使得引入CFSOH（TMSA）的干凝胶在无水条件下获得了高质子传导率，从9.0×10 S cm（253 K）到1.40×10 S cm（363 K），处于领先水平。这为开发宽工作温度导体提供了新可能性。
