This study provides new insights into the fabrication of high-performance Pt-based catalysts for indoor air purification. Moreover, deactivation rate increases with increasing diameter of halogen ions. The adsorbed ions form coordination bonds with surface Pt atoms by transferring surplus electrons into the unoccupied 5d orbit of the Pt atom, thereby inhibiting oxygen adsorption and activation of the Pt NP surface. The poison mechanism is due to the strong adsorption of halogen ions on the surface of Pt NPs. Characterization results (including XRD, TEM, HRTEM, BET, XPS, and metal dispersion) showed that the adsorbed halogen ions can poison Pt nanoparticles (NPs), thereby reducing the HCHO oxidation activity of Pt-TiO 2. Pt-TiO 2 samples with adsorbed halogen ions exhibited reduced catalytic activity for formaldehyde decomposition at room temperature compared with the Pt-TiO 2 sample the catalytic activity followed the order of F-Pt-P25, Cl-Pt-P25, Br-Pt-P25, and I-Pt-P25. Guillaume Rochard, directeur Stratégie, Partenariats et Fusions-acquisitions de Naval Group, rejoint le Comité exécutif. Alison Moskowitz Memorial Sloan Kettering. Au catalysts with loadings of 1.5 and 3 wt were dispersed over CeO2 and Co (9 12 mol) promoted CeO2, using the depositionprecipitation method, followed by calcination at 350 C. Andre Schuh Princess Margaret Cancer Centre. In this study, Pt-TiO 2 (Pt-P25) catalysts with and without adsorbed halogen ions (including F −, Cl −, Br −, and I −) were prepared through impregnation and ion modification. Guillaume Richard-Carpentier Princess Margaret Cancer Centre Dr. However, the stability of this catalyst remains unexplored. 'Recent Advances in the Catalytic Treatment of. Pt-based catalysts are the optimal catalyst for HCHO decomposition at room temperature. Rochard, Guillaume, Lilian Olivet, Mariebelle Tannous, Christophe Poupin, Stphane Siffert, and Renaud Cousin. Émile Calixte Rochard (3 July 1851, Wissembourg May 1918, Paris) was a 19th20th-century French playwright, novelist and poet. Guillaume & Virginie Philip, Guillaume Gilles, Guillot-Broux, Guimaro. Catalytic decomposition of formaldehyde (HCHO) at room temperature is an important method for HCHO removal. Universitatea Tehnica Gheorghe Asachi din Iasi, Chemistry, FRANCE.
