Mechanochemical redox synthesis of interstitial mesoporous CoxFe1‐xOy catalyst for CO2 hydrogenation

Abstract: The study on CoOx‐FeOx catalysts gives a profound insight into the synthesis and the application of multitransition metal oxide catalysts. A facile and solid‐state mechanochemical redox strategy was developed to obtain CoxFe1‐xOy from CoCl2·6H2O and KMnO4 with simply two‐round of ball milling (BM) operation. The process was witnessed by the Brunauer—Emmett—Teller (BET), X‐ray diffraction (XRD), scanning transmission electron microscope (STEM), inductively coupled plasma emission spectrometry (ICP), and X‐ray p… Show more

“…The authors used the same method to synthesize mesoporous CeWO x oxide catalysts with high specific surface area (143 m 2 •g −1 ) by mixing cerium salt, tungsten salt, and F127 (Figure 8D). 107 Meng et al 108 Compared with traditional liquid-phase synthesis approaches, the mechanochemical method has the advantages of solventfree conditions, which reduces the solvent consumption and the accumulation of liquid byproducts. In addition, compared with the hydrothermal method, the mechanochemical synthesis greatly reduces the synthesis time.…”

“…The authors used the same method to synthesize mesoporous CeWO x oxide catalysts with high specific surface area (143 m 2 ·g –1 ) by mixing cerium salt, tungsten salt, and F127 (Figure D) . Meng et al developed a facile mechanochemical redox strategy in the solid state to obtain Co x Fe 1– x O y (Figure E) from CoCl 2 ·6H 2 O and KMnO 4 simply through two rounds of BM. Importantly, the as-made Co x Fe 1– x O y -BM sample possessed abundant porosity, and its specific surface area (131 m 2 ·g –1 ) was much higher than that of the samples obtained via the coprecipitation (49 m 2 ·g –1 ) and sol–gel (33 m 2 ·g –1 ) routes.…”

“…Minshan Meng et al [125] Rojas Cervantes and colleagues investigated the use of catalysts of perovskite oxide-based oxidation for wastewater treatment using various oxidants and so UV-visible irradiation producing photocatalysis [127]. The researchers investigate the physicochemical aspects of perovskite oxides like lattice oxygen vacancy and mobility formation as well as maintaining distinct states of oxidation of component elements which may be used to increase AOP employing radicals [128].…”
