The design and synthesis of low-cost,
excellent catalytic activity
catalysts is the key to catalytic oxidation of VOCs. Nanomaterials
have attracted great interest in recent years. Here, a simple impregnation
method was used to synthesize the Cu-doped CeO2 nanostructure
catalyst supported on a boron-rich carbon carrier and applied for
the catalytic oxidation of acetone. After trace amounts of Cu were
added to the single CeO2 supported on boron-rich carbon
catalyst, Cu-doped CeO2 catalyst displayed better catalytic
activity. Besides, it also has long-term stability and H2O resistance. The influence of copper doping on the performance of
the catalyst was studied by many characterization technologies. The
result indicated that the introduction of Cu can further limit the
growth of CeO2 grains based on the limited growth of metal
nanoparticles on the carrier, can make the amounts of Ce3+ and adsorb oxygen species increase, and can enhance the redox properties
of CeO2. Therefore, Cu-doped CeO2 nanostructures
in a boron-rich carbon catalyst have the potential for the removal
of acetone.
