摘要:

电催化质子加氢反应是能源转化、化学合成和环境修复等领域的核心反应过程. 传统上, 这类反应通常在酸性介质中进行, 以利用高浓度的H3O+作为质子供体, 实现高效的质子供给. 然而, 强酸性条件带来了严重的设备腐蚀、产物分离困难和大量废酸排放等环境与经济负担. 相比之下, 中性反应环境具有绿色、可持续且与生物体系兼容等显著优势, 但其极低的体相质子浓度导致了一系列严峻的挑战, 主要包括: 依赖水分子解离的质子供给动力学缓慢、热力学上更有利的析氢反应竞争激烈、气体反应物在中性水中的溶解度低导致传质受限, 以及多步反应路径复杂和电极界面微环境的动态不稳定. 因此, 系统解析中性介质中质子加氢反应的机理并发展高效的性能优化策略, 对于推动该技术的实际应用具有重要意义.

围绕上述核心挑战, 本文从三个尺度维度系统梳理了前沿性能优化策略. 在本征催化剂结构设计层面, 聚焦于通过电子结构与几何构型的精确调控, 协同提升水分子解离效率和活性氢物种的定向利用能力. 主要策略包括: 通过配位环境工程构筑单原子催化剂, 优化水活化能垒和中间体吸附能; 构建双位点协同催化体系, 利用氢溢流机制将产氢与加氢功能解耦, 抑制析氢反应; 利用缺陷工程构建不饱和配位中心, 增强水活化能力并稳定关键中间体. 在界面质子传输强化层面, 致力于构建高效的界面质子传输网络以克服传递瓶颈. 策略包括: 通过界面功能化引入官能团构建表面质子传导通路; 在有序框架中构筑仿生氢键网络, 实现快速定向质子输运; 引入光、热等外场, 重构质子-电子耦合的时空路径. 在反应工程与系统集成层面, 通过反应器与工艺流程的创新设计协同优化传质与反应路径. 核心策略包括: 构建气体扩散电极形成三相界面, 解除气态反应物的传质限制; 引入缓冲介质稳定界面pH并直接参与质子供给; 发展膜电极组件和串联催化技术, 精确管理界面离子传输并分解复杂反应网络, 提升目标产物选择性.

综上, 本文系统总结了中性介质中质子加氢反应的反应机理与核心挑战, 从本征催化剂设计、界面质子传输强化和反应工程与系统集成三个维度归纳了前沿优化策略及其内在关联. 本综述旨在加深领域研究者对中性介质质子加氢体系的系统性认知, 为进一步开发高效、稳定的中性质子氢化技术, 推动其在绿色化学合成与清洁能源转化领域的实际应用提供一定的参考和借鉴.

Abstract:

Proton hydrogenation reactions underpin numerous core processes in energy conversion, chemical production, and environmental remediation. While traditional acidic environments provide ample proton sources, they pose challenges such as equipment corrosion and environmental pollution. Neutral environments effectively mitigate these issues and offer broader application compatibility. However, their extremely low proton concentrations lead to challenges including slow proton supply kinetics, intensified competitive hydrogen evolution reactions, limited mass transfer of reactants, and destabilization of the interfacial microenvironment. This review systematically analyzes the reaction mechanisms and key challenges of proton hydrogenation in neutral environments. It summarizes cutting-edge strategies for performance enhancement across three dimensions: Intrinsic catalyst structure design, enhanced interfacial proton transfer, and optimization of reaction pathways and mass transport processes. Finally, it outlines future research directions including in situ mechanism studies, catalyst stability enhancement, and system energy efficiency optimization, aiming to provide theoretical guidance for constructing efficient and stable proton hydrogenation catalytic systems in neutral environments.
