“…In our previous works we prepared, characterized and successfully tested for C 3 /C 4 alkanes combustion the ZnAl 2 O 4 spinel as support for platinum [15] or ruthenium catalysts [16]. The aim of the present work was to study the effect of substitution of Zn 2+ by Fe 2+ ions and Al 3+ by Co 3+ ions in the framework of zinc aluminate spinel on its structural and catalytic properties for diluted propane combustion.…”

“…[5][6][7][8][10][11][12][13] So far, noble metal-based catalysts, especially Pt-based ones, are known to be the most active catalyst at low temperature for thermal oxidation of VOCs. 5,6,14 However, their high costs and limited abundance make it difficult to use them in large-scale applications. Thus, noble-metal free catalysts based on other transition metal-oxides (MnO, CuO, Co 3 O 4 , NiO, etc.)…”

“…2,3 In addition, some toxic photochemical oxidants and suspended particulate matters can be produced as a result of photochemical reactions of VOCs under light irradiations. [4][5][6] Many different ways, such as adsorption, pyrolysis, photocatalytic degradation, and catalytic oxidation, have been suggested and investigated for removing VOCs pollutants. Among those, catalytic oxidation of VOCs has been considered as one of the most promising ways due to its high destruction efficiency.…”

Carbon-fiber-supported NiO catalytic filters for oxidation of volatile organic compounds were prepared by electroless Ni-P plating and subsequent annealing processes. Surface structure and crystallinity of NiO film on carbon fiber could be modified by post-annealing at different temperatures (500 and 650 o C). Catalytic thermal decompositions of toluene over these catalytic filters were investigated. 500 o C-annealed sample showed a higher catalytic reactivity toward toluene decomposition than 650 o C-annealed one under same conditions, despite of its lower surface area and toluene adsorption capacity. X-ray diffraction and X-ray photoelectron spectroscopy studies suggest that amorphous structures of NiO on 500 o C-annealed catalyst caused the higher reactivity for oxidation of toluene than that of 650 o C-annealed sample with a higher crystallinity.

“…Transition metal catalysts are more efficient on a cost basis as compared with precious metal ones; however, the former exhibits lower activity for VOCs combustion [7][8][9]. On the other hand, precious metal catalysts can achieve the complete oxidation at low temperature due to their high activity [10][11][12][13]. For the MeOH oxidative decomposition process, Pt [14], Ru [15,16], Au [17][18][19], and Ag [20][21][22][23][24][25] metals have been well researched as active metals.…”
