“…Catalytic oxidation is one of the most effective pathways in eliminating VOCs. In recent years, precious metal-based catalysts have been used in the catalytic oxidation of VOCs [2]. Moreover, the support in this type of catalyst plays a determinant role in improving its catalytic activity.…”

The Pd catalyst supported on cryptomelanetype manganese oxide octahedral molecular sieve (OMS-2) were prepared. The effect of Pd loading on the catalytic oxidation of carbon monoxide, toluene, and ethyl acetate over xPd/OMS-2 has been investigated. The results show that the Pd loading plays an important role on the physicochemical properties of the xPd/OMS-2 catalysts which outperform the Pd-free counterpart with the 0.5Pd/ OMS-2 catalyst being the best. The temperature for 50% conversion was 25, 240 and 160°C, and the temperature for 90% conversion was 55, 285 and 200°C for oxidation of CO, toluene, and ethyl acetate, respectively. The lowtemperature reducibility and high oxygen mobility of xPd/ OMS-2 are the factors contributable to the excellent catalytic performance of 0.5Pd/OMS-2.

“…[5][6][7][8][9][10][11][12][13][14] Recently,t hermalc atalytic oxidation (TCO) under ambient condition has been considered as one of the most promising approaches to remove HCHO because TCO is characterized by environmentally friendly reactionc onditions and low energy consumption.S everal studies on the preparation and development of TCO catalysts have been performed; these TCO catalysts are designed to remove HCHO at ambient temperature. [6,[12][13][14][15][16][17][18][19] Pt-containing catalysts are receiving considerable attention because Pt-containing catalysts exhibit good catalytic performance and durability at ambient temperature. For instance, the completec onversion of HCHO to CO 2 and H 2 Oa ta mbient temperature can be achieved using Pt/ TiO 2 , [6,[11][12][13][14][15] Pt/Al 2 O 3 , [7] Pt/MnO 2 , [16] Pt/MnOx-CeO 2 , [17] and Pt/ Fe 2 O 3 .…”

Hierarchical macro-mesoporous Pt/NiO hollow microspheres are synthesized and used for catalytic decomposition of formaldehyde in air at room temperature. The uncalcined Pt-Ni(OH) 2 sample exhibits low catalytic activity.T he Pt/NiO sample heateda t3 00 8Cs hows significantly enhanced catalytic activity.T he Pt/NiO sample at 400 8Ce xhibits the highest catalytic activity,m ainly due to its bimodal macro-mesoporous structure with open and accessible pores, which provides al arge specific surface for HCHO ad-sorptiona nd Pt dispersion, enables the fast diffusion and transport of gas molecules,a nd ensures the accessibility of active sites on Pt nanoparticles for gas molecules. Moreover, all Pt/NiO hollow spheres have higher catalytic activity than Pt-decorated commercial NiO. The preparedh ierarchical macro-mesoporous Pt/NiO nanocomposite hollow microspheres should also find applications in adsorption, photocatalysis, electrocatalysis, separation, and purification processes.[a] Dr.
