Pd/meso-CoO derived from in situ reduction of the one-step synthesized Pd/meso-Co₃O₄: high-performance catalysts for benzene combustion

Abstract

The 0.93Pd/meso-CoO is prepared via in situ reduction of 0.85Pd/meso-Co3O4 derived from KIT-6-templating method. The excellent catalytic activity of 0.93Pd/meso-CoO is related to the formed Pd0 species and good oxygen activation ability.

Recent progress on catalysts for catalytic oxidation of volatile organic compounds: a review

“…Many reports have proposed that Pd 0 was the active site of VOC oxidation over Pd-based catalysts. [164][165][166] Meng et al 167 synthesized the Pd/ NiO catalyst adopting supercritical water (sc-H 2 O) as a medium and achieved the in situ modification of Pd valence under reduction or oxidation atmosphere (Fig. 12C).…”

Advances in Catalytic Oxidation of Volatile Organic Compounds over Pd-Supported Catalysts: Recent Trends and Challenges

“…Numerous studies have demonstrated that the catalytic activity of Pd-supported catalysts is closely related to the oxidation state of Pd (Li et al, 2011;Gil et al, 2015;Zhao et al, 2016;Weng et al, 2019;Zhao X. et al, 2019). Some authors proposed that metallic Pd was more active in VOC oxidation than its oxidized state (Tidahy et al, 2008;Huang and Leung, 2011;Wang et al, 2018a;Zhao X. et al, 2019), as it can provide more active sites for the oxidation of hydrocarbons (Jinjun et al, 2005). The superior catalytic performance of Pd/ TiO 2 for HCHO oxidation relied on the metallic Pd NP with a strong capacity for oxygen activation (Huang and Leung, 2011).…”

The promotion effect of Sn on Cr/KIT-6 for the catalytic combustion of chlorobenzene

“…14,15 Among these materials, KIT-6 exhibits a special three-dimensional pore structure, demonstrating excellent adsorption–desorption capacities for different gases. 16–18 Thus, KIT-6 is an excellent option as a catalyst carrier to achieve high dispersion of metal oxides as well as high diffusion of reaction substrates.…”
