Gold nanoparticles supported on halloysite nanotubes (Au/HNTs) were prepared by a homogeneous deposition-precipitation method. The specific characteristics of the catalyst were characterized in detail, in relation to their performance for solvent-free oxidation of benzyl alcohol. The particular structure of the catalyst resulted in high catalytic activity and stability compared with other supported gold catalysts. The enhanced catalytic activity of the Au/HNTs catalyst was mainly attributed to the presence of a higher amount of oxidized gold species and the tubular structure of the HNTs.
负载在埃洛石纳米管上的金纳米粒子（Au/HNTs）是通过均相沉淀法制备的。详细考察了催化剂的特殊性质，以及其在无溶剂条件下氧化苯甲醇的性能。与其他负载型金催化剂相比，该催化剂具有独特的结构，表现出较高的催化活性和稳定性。Au/HNTs 催化剂具有较高的催化活性，主要归因于其具有更多的氧化态金物种和埃洛石纳米管的管状结构。
