Single-atom confined materials (SACMs) have been widely researched as catalysts in many field recent years. However, this class of materials may not only serve as catalyst but as support of certain reactions. Here, we propose a general strategy to use these SACMs as support for readily tuning the loaded noble metal (e.g., Ru) nanoparticles with enhanced catalytic activity. As a proof of concept, a nickel single-atom confined nitrogen-doped carbon nanotube (NCNT) superstructure was prepared as support for loading noble metal Ru for catalytic wet air oxidation of acetic acid. The improved catalytic activity with mineralization rate of ~97.5% has been achieved Further, the adsorption configurations based on DFT method also confirms our deduction the introduction of single-atom Ni changes the intrinsic property of NCNT and affects the loaded active Ru nanoparticles.
