Abstract
- Formaldehyde oxidation at room temperature with low-cost catalysts is one of the main development directions of environmental governance. Herein, we developed a low-cost and superior performance highly dispersed Ce on Na-ZSM-5 (Ce/Na-ZSM-5) catalyst, which is close to atomic dispersion for indoor formaldehyde (HCHO) oxidation at low temperature. The highly dispersed catalyst that was similar to atomic dispersion was characterized by EXAFS and AC HAADF-STEM. The optimal Ce/Na-ZSM-5 displays high HCHO removal performance (95%, at room temperature), as well as 100 h stable testing (∼90% HCHO removal). In addition, a reasonable reaction mechanism of the HCHO catalytic oxidation is proposed based on the in situ DRIFT spectra and DFT calculation. This work provides a new way to design an efficient catalyst for the complete oxidation of formaldehyde. [ABSTRACT FROM AUTHOR]
