Pt/MnO2-BN aerogels exhibit superior catalytic activity and strong adsorption capacity, which can promote the rapid reduction and complete oxidation of HCHO gas-phase concentration.
The catalytic room temperature oxidation of formaldehyde (HCHO) is widely considered as a viable method for the abatement of indoor toxic HCHO pollution. Herein, Pt/MnO2 nanoflowers anchored to boron nitride aerogels (Pt/MnO2-BN) were fabricated for the catalytic room temperature oxidation of HCHO. The three-dimensional Pt/MnO2-BN aerogels demonstrated superior catalytic activity as a result of the improved diffusion of the reactant molecules within the porous structure. Furthermore, the porous aerogels displayed excellent HCHO adsorption capacities, which promote a rapid HCHO gas-phase concentration reduction and a subsequent complete oxidation of the adsorbed HCHO. The combined adsorption and oxidation properties of the Pt/MnO2-BN aerogels enhance the oxidative removal of HCHO. The optimized Pt/MnO2-BN demonstrated excellent catalytic activity toward HCHO (200 ppm) at room temperature, achieving a 96 % formaldehyde conversion after 50 min.
