Figure 4 The catalytic performance of the Au/HNTs catalyst as a function of reaction time. Conclusions In conclusion, we have demonstrated that HNTs are an attractive support for gold nanoparticles, which results in an excellent catalytic activity www.selleckchem.com/products/epz-5676.html in solvent-free oxidation of benzyl alcohol. The high catalytic activity is found to be related to the tubular structure of the HNTs and the oxidized gold species. This process is promising in the development of a truly heterogeneous

catalyst for alcohol oxidation.
