摘要

液态有机氢载体(LOHC)技术是实现氢能规模储运与分布式供能的关键路径。吲哚类LOHCs因高安全性和设施兼容性，展现出广阔的应用前景，其商业化应用的核心在于高效催化体系的研发。基于此，本文综述了吲哚类LOHCs储放氢反应机制，梳理了应用于吲哚类LOHCs储放氢反应的催化剂，阐述了催化剂结构与性能之间的关系，并分析了反应温度、压力和溶剂性质等因素对催化性能的影响。指出当前催化体系存在对贵金属的依赖程度高、活性组分原子利用率低以及长周期运行稳定性不足等问题。未来研究应聚焦于开发活性组分负载量低的原子级分散催化剂，以降低成本、提高原子利用率。借助原位表征技术与理论计算揭示氢溢流效应以及中间产物转化等微观机制，为催化剂精准设计提供理论依据。结合反应器设计优化等过程强化方法，实现温和条件下高效储放氢以及催化剂与储氢载体的循环利用，以推动吲哚类LOHCs在氢能储运中的产业化应用。

Abstract

Liquid organic hydrogen carrier (LOHC) technology is a key pathway to large-scale hydrogen storage

transport

and distributed energy supply. Indole-based LOHCs show strong potential owing to their excellent safety and compatibility with existing petroleum infrastructure. The development of efficient catalytic systems is crucial to advancing the commercialization of indole-based LOHCs. Accordingly

this review summarizes the hydrogen storage and release mechanisms of indole-based LOHCs

systematizes catalysts developed for these reactions

elucidates the structure-performance correlations of catalysts

and analyzes the influence of key factors

including reaction temperature

pressure

and solvent properties

on catalytic performance. Nevertheless

current catalytic systems still face limitations such as reliance on noble metals

low atomic utilization of active components

and inadequate long-term stability. To address these issues

future efforts should focus on developing atomically dispersed catalysts with low metal loading to reduce costs and enhance atomic efficiency. Moreover

combining in situ characterization techniques and density functional theory calculations can elucidate underlying mechanisms

such as hydrogen spillover and intermediate conversion

and guide the rational design of catalysts. Integrating process-intensification strategies

including advanced reactor design

will further enable mild-condition operation and efficient regeneration of catalysts and LOHCs

ultimately accelerating the industrial application of indole-based LOHCs in hydrogen energy storage and transport.
