摘要/Abstract

摘要：

甲烷(CH₄)是仅次于二氧化碳的第二大温室气体. 在生产、运输和使用过程中, CH₄泄漏或排放将导致严重环境和气候问题. 然而, CH₄分子中C-H键能高达434 kJ mol^-1, 低温条件下完全转化存在巨大挑战. 单原子催化剂具有有效调节活性位点化学环境的能力, 能够协同增强催化反应性能. 但是单原子与团簇协同增强的内在机制尚未完全阐明. 本文旨在通过设计合成单原子-团簇催化剂用于CH₄催化燃烧, 明晰单原子-团簇协同机制, 实现高效低温CH₄燃烧.
本文设计了单原子Ni掺杂CeO₂负载Pd团簇催化剂(Pd/Ni₁-CeO₂)用于CH₄催化燃烧. 球差校正透射电子显微镜和X射线吸收精细结构表征显示, Pd/Ni₁-CeO₂催化剂中Ni物种以Ni₁-O₄配位构型的单原子形式存在, 而Pd物种则以团簇形式存在. X射线衍射和拉曼光谱结果表明, 单原子Ni掺杂入CeO₂晶格, 导致CeO₂发生晶格畸变, 增加了表面氧空位(Ov)浓度. X射线光电子能谱结果表明, 与Pd/CeO₂相比, Pd/Ni₁-CeO₂中表面氧的比例增加到68.3%, 并且Pd⁴⁺的比例上升到70.8%. 第一性原理计算(DFT)和差分密度模拟结果显示, 单原子Ni掺杂入CeO₂晶格, 导致CeO₂发生晶格畸变, 增加了表面氧空位(O_v)浓度, 进一步诱导Pd原子中的电子流向邻近的Ni原子和O原子, 产生更多的高价Pd⁴⁺. 与未掺杂单原子的Pd/CeO₂催化剂相比, Pd/Ni₁-CeO₂催化剂展现出更佳的CH₄燃烧活性. 在350 ºC时, CH₄的反应速率提升至2.19 × 10^-6 mol g^-1 s^-1和转换频率达到2.30 × 10^-2 s^-1. 动力学实验和DFT计算结果表明, Pd⁴⁺和O_v协同降低了CH₄分子中C-H键的断裂能垒并促进了O₂分子的吸附解离, 进而增强CH₄催化燃烧活性. 原位漫反射红外傅里叶变换光谱结果表明, Pd/Ni₁-CeO₂催化剂催化CH₄燃烧遵循Mars-van Krevelen机制. 此外, Pd/Ni₁-CeO₂催化剂还具有良好的长期稳定性、耐水性能和耐SO₂性能.
综上, 本工作阐明了单原子Ni对Pd团簇电子结构的调控机制及其对CH₄催化燃烧反应的增强作用, 从而实现了高效的低温CH₄催化燃烧, 为合理设计和合成高效催化剂提供了理论和实践指导.

Abstract:

Single-atom catalysts possess the ability to effectively modulate the chemical environment of active sites, thereby synergistically enhancing catalytic reaction activity due to their unique electronic properties. In this study, single-atom Ni-doped CeO₂-supported Pd catalysts were designed and synthesized. The introduction of single-atom Ni induced lattice distortion in the CeO₂ support, resulting in an increased concentration of oxygen vacancies on the surface. This increase in oxygen vacancies enhances the strong metal-support interactions between Pd and the support. Under the intensified metal-support interaction effect, Pd species tend to transfer more electrons to Ni atoms and adjacent O atoms, leading to a higher proportion of high oxidation states (Pd⁴⁺) in PdO_x species. The presence of high-valent Pd⁴⁺ and oxygen vacancies synergically enhances the activation of C-H bonds in methane and the adsorption and dissociation of oxygen, significantly improving the overall catalytic activity of methane combustion. This study provides a critical theoretical foundation and practical guidance for the design and optimization of clean energy catalysts.
