Enhanced and Sustainable Removal of Indoor Formaldehyde by Naturally Porous Bamboo Activated Carbon Supported with MnO_x: Synergistic Effect of Adsorption and Oxidation.

ABSTRACT: Novel bamboo activated carbon (BAC) catalysts decorated with manganese oxides (MnO_x) were prepared with varying MnO_x contents through a facile one-step redox reaction. Due to the physical anchoring effect of the natural macropore structure for catalyst active components, homogeneous MnO_x nanoparticles (NPs), and high specific surface area over catalyst surface, the BAC@MnO_x-N (N = 1, 2, 3, 4, 5) catalyst shows encouraging adsorption and catalytic oxidation for indoor formaldehyde (HCHO) removal at room temperature. Dynamic adsorption and catalytic activity experiments were conducted. The higher S_micro (733 m²/g) and V_micro/V_t (82.6%) of the BAC@MnO_x-4 catalyst could facilitate its excellent s
