文献中已经提出了金和载体金属氧化物之间暴露界面的重要性。在这里，我们总结了为此类活性位点和发生的潜在反应机制提供强有力支持的证据以及相互矛盾的证据。总结了三个反应的证据：CO 氧化、水煤气变换 (WGS) 反应和丙烷选择性氧化。讨论了对未来潜在研究的影响以及真正设计选择性催化剂的能力。
The importance of the exposed interface between Au and the support metal oxide has been suggested in the literature. Here we summarize evidence that provide strong support as well as conflicting evidence for this type of active sites and the potential reaction mechanism that takes place. Evidence from three reactions are summarized: CO oxidation, water gas shift (WGS) reaction, and selective oxidation of propane. Implications for potential future research and ability to truly design selective catalysts are discussed.
