Abstract

Hydrogen energy will play a dominant role in energy transition from fossil fuel to low carbon processes, while economical, efficient, and safe hydrogen storage and transportation technology has become one of the main bottlenecks that currently hinder the application of the hydrogen energy scale. Methanol has widely been regarded as a primary liquid H2 storage medium due to its high hydrogen content, easy storage and transportation and relatively low toxicity. Hydrogen release from methanol using photocatalysis has thus been the focus of intense research and recent years have witnessed its fast progress and drawbacks. This review offers a comprehensive overview of methanol-based hydrogen production via photocatalysis, spotlighting recent developments in photocatalysts referring to thermal catalysts, including efficient semiconductors and cocatalysts, followed by the discussion of mechanistic investigation via advanced techniques and their disadvantages. Beyond this, particular focus has been placed on the discussion of co-driven processes involving coupling of photons (photocatalysis) with phonons (thermal catalysis) – the concept of photon–phonon co-driven catalysis – for methanol reforming and cutting-edge reactor design strategies, in order to enhance the overall process efficiency and applicability. Concluding with forward-looking insights, this review aims to provide valuable guidance for future research on hydrogen release through methanol reforming.

从光催化到光子-声子共驱动催化甲醇重整制氢和有价值的副产物
氢能将在能源从化石燃料向低碳转型过程中发挥主导作用,而经济、高效、安全的储氢和运输技术已成为目前阻碍氢能规模化应用的主要瓶颈之一。甲醇因其含氢量高、易于储存和运输、毒性较低而被广泛认为是主要的液氢储存介质。因此,利用光催化技术从甲醇中释放氢一直是研究的热点,近年来该技术的发展迅速,但也存在一些不足。本文综述了甲醇基光催化制氢的研究进展,重点介绍了热催化剂(包括高效半导体和辅助催化剂)的最新进展,然后讨论了先进技术的机理研究及其缺点。除此之外,特别关注的是涉及光子(光催化)与声子(热催化)耦合的共驱动过程的讨论-光子-声子共驱动催化的概念-用于甲醇重整和尖端反应器设计策略,以提高整体工艺效率和适用性。本文旨在为今后甲醇重整释氢研究提供有价值的指导。
