摘要

Room-temperature catalytic decomposition of formaldehyde (HCHO) is regarded as one of the best methods for indoor HCHO purification and removal. Herein, for the first time, a flexible and bendable Mg-Al layered double hydroxide (LDH) on aluminum (Al) foil was in situ prepared and further decorated with platinum (Pt) nanoparticles (NPs) for catalytic oxidation decomposition of HCHO at room temperature. Such a Pt-loaded large-area flexible LDH catalyst can be directly used and easily regenerated because of its flexibility and relatively low production cost. Moreover, it exhibited excellent catalytic performance toward oxidation decomposition of HCHO at room temperature due to its hierarchical macro-/mesoporous structure that facilitates the diffusion of reactants and products. Furthermore, abundant hydroxyl groups on the catalyst surface are also beneficial to HCHO oxidation decomposition. This work may provide some new insight into the design and fabrication of advanced catalysts for indoor HCHO removal and air purification.
