Catalytic combustion of formaldehyde on gold/iron-oxide catalysts

Comparative studies of silver based catalysts supported on different supports for the oxidation of formaldehyde

“…It has also been found that the highly dispersed and poorly crystallized metallic gold and small amount of oxidized gold in the CeO 2 support catalysts exhibited superior activity for HCHO oxidation at temperatures close to 100 • C [14]. However Fe-O supported Au catalyst gave different gold active sites and activity [29]. Thus it was clearly exhibited that the support showed a strong influence on the nature of the active species and its catalytic activity.…”

Synthesis and Characterization of Iron Oxide Nanoparticles Supported on Ziconia and Its Application in the Gas-Phase Oxidation of Cyclohexanol to Cyclohexanone

“…FT-IR spectra (Figure 3) of freshly prepared sample exhibited peaks at 3300, 1642 and 1300 cm −1 corresponding to the O-H group, carboxyl group and 3 …”

“…Continuous efforts have been made to reduce size of the particles with a simultaneous focus on preserving and enhancing the dispersion, in order to improve the quality and affordability of these iron-based catalysts. Several attempts have been made to prepare iron oxides and explore their catalytic activities in petrochemical industries [1][2][3][4][5][6][7][8][9]. Research has established the enhancing effect of promoters on the catalytic activity of iron-based catalysts, for example, molybdenum promotes the catalytic activity of sulfated hematite while tungsten has additive effect when used in combination with molybdenum.…”

“…Recently, researchers have diverted attention towards nano-materials and their applications in the field of catalysis. In this scenario, iron oxide nanoparticle is a potent candidate to be investigated as a catalyst in various industrially important reactions, including the synthesis of NH 3 , water shift reaction, desulfurization of natural gas, dehydrogenation of ethyl benzene, oxidation of alcohol, and manufacture of butadiene [13][14][15][16][17][18].…”

Synthesis, morphology, microstructure and magnetic properties of hematite nanoparticles

“…Hematit se koristi kao katalizator za mnoge industrijski vaţne hemijske reakcije, uključujući sintezu NH 3 (Haber-ov proces) i za izdvajanje sumpora iz prirodnog gasa. Ostale reakcije uključuju dehidrogenizaciju etil benzena do stirena i proizvodnju butadiena [11,[85][86][87][88][89][90][91][92][93][94][95].…”
