开发用于能源技术和环境修复的新型催化剂需要对催化剂的物理和化学性质如何影响其反应性有透彻的了解。对于支持的金属纳米颗粒（NPs），这些特性可以包括颗粒大小，形状，组成和化学状态，但一个不可忽视的关键参数是NP支持的作用。在这里，我们强调了支持诱导金属NPs催化性能增强的关键机制。这些变化包括支持诱导的NP形态、稳定性、电子结构和化学状态的变化，以及由于NP引起的支持的变化。利用本观点中描述的依赖于载体的现象，可能会在设计和定制金属纳米颗粒的催化活性和选择性方面取得重大突破。
The development of new catalysts for energy technology and environmental remediation requires a thorough knowledge of how the physical and chemical properties of a catalyst affect its reactivity. For supported metal nanoparticles (NPs), such properties can include the particle size, shape, composition, and chemical state, but a critical parameter which must not be overlooked is the role of the NP support. Here, we highlight the key mechanisms behind support-induced enhancement in the catalytic properties of metal NPs. These include support-induced changes in the NP morphology, stability, electronic structure, and chemical state, as well as changes in the support due to the NPs. Utilizing the support-dependent phenomena described in this Perspective may allow significant breakthroughs in the design and tailoring of the catalytic activity and selectivity of metal nanoparticles.
