 The fabrication protocol involves reducing and loading metal layers onto titanium dioxide nanotubes. This process allows for the controlled growth and dispersion of platinum and copper metallic layers. The resulting structure has a lower specific surface area than before, but also contains more pores of different sizes. The catalytic activity of the point at CU-X slash T02 increases with higher loadings of the bimetal nanocrystal and reaches its maximum at around 9%. The catalyst remains stable after five cycles of use, retaining 91% of its original catalytic activity. This article was authored by Bing Wang Mao, Yiming Zhu, Biwa Huang, and others.
