A Novel Ru Loaded Hydroxyapatite Catalyst Prepared by a Facile and Efficient Deposition Method for Catalytic Oxidation of Toluene and Dichloromethane
Ru/HAP catalyst with high-dispersion is prepared by a novel homogeneous deposition precipitation method (DPU). As compared to the conventional impregnation method (IM), the catalytic oxidation performance for toluene and DCM are much higher for DPU-sample with higher activity and good stability in humid air. Characterizations reveal that DPU-sample has a larger surface area with mesoporous structure, keeping smaller Ru particle size and uniform distribution on HAP, which is favorable for the exposure of active sites. The preparation and reaction conditions were also systematically studied, showing that 0.5 Ru/HAP(500)-DPU sample is a promising catalyst for VOC and CVOC removal.
Graphical Abstract
The Ru/HAP (DPU) is a promising broad-spectrum catalyst for VOC and CVOC removal.
期刊介绍：
Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis.
The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
