Hierarchical Pt/NiO hollow nanofibers for catalytic oxidation of HCHO at room temperature

Formaldehyde (HCHO), a significant indoor air pollutant, poses serious health risks to humans, making its removal a critical issue. Among the various methods for HCHO elimination, catalytic oxidation has emerged as one of the most efficient and practical approaches. In this study, hierarchical hollow nickel oxide nanofibers (NiO–HNF) are developed by using a semi-sacrificial template-assisted hydrothermal and calcination process. Platinum (Pt) nanoparticles are then loaded onto the NiO–HNF through an impregnation-chemical reduction process. The Pt/NiO–HNF nanocomposite demonstrates a marked improvement in HCHO decomposition activity at room temperature, which can be ascribed to its distinct structural features. The hierarchical structure of the nanocomposite, which provides a high specific surface area and abundant porosity, facilitates the uniform dispersion of Pt nanoparticles and increases the number of active sites available for catalysis. To further investigate the oxidation mechanism, in-situ diffuse reflectance infrared Fourier transform spectroscopy (in-situ DRIFTS) is utilized. The findings suggest that the main intermediates during the oxidation process are dioxymethylene and formate species. This study highlights the potential of hollow transition metal oxide composites as efficient materials for the removal of indoor air pollutants.
