Formaldehyde (HCHO) catalytic decomposition at room temperature is an important method for HCHO removal in indoor environment. Herein, flower-like γ-Al2O3 microspheres with high specific surface area, special textural structure, and abundant surface defects were prepared through a one-pot hydrothermal method by using aluminum foil as Al source. And it was used as oxide support to prepare highly-dispersed Pt catalyst (Pt/Al2O3). Compared with Pt supported on commercial γ-Al2O3, the as-prepared Pt/Al2O3 showed enhanced catalytic activity for HCHO decomposition at room temperature. This work provides new insights into designing and fabricating highly-dispersed Pt catalysts for efficient indoor air purification.
