Preparation of mesoporous Fe-Cu mixed metal oxide nanopowder as active and stable catalyst for low-temperature CO oxidation

Catalytic Oxidation of CO over Nanocrystalline La1–xCexNiO3 Perovskite‐Type Oxides

“…The decrease in the initial conversion of CO was around 5 % for 10 % CO 2 + 5 % H 2 O in the feed after 24 h. The drop in activity at dry feed composition is less than that observed in the presence of 10 % CO 2 + 5 % H 2 O in the feed. This decline in activity is due to the coverage of the surface‐active sites of the catalyst by CO 2 and H 2 O, which hinders the adsorption of CO and O 2 on the surface‐active sites .…”

A holistic analysis of surface, chemical bonding states and mechanical properties of sol-gel synthesized CoZn-oxide coatings complemented by finite element modeling

“…By adopting a suitable synthesis method, one can regulate the structural, chemical and surface morphology, and particle size of a material to be used in the desired technical applications. Nowadays, numerous methods are available to synthesize mixed metal oxide based thin film coatings or nanoparticle structures namely, hydrothermal process, chemical co-precipitation route, laser deposition method, polyol process, thermal decomposition method, electrochemical method, microwave assisted technique, standard ball milling scheme, sol-gel dip coating or spin coating procedure, and thermal evaporation approach [42][43][44][45][46][47][48][49]. The majority of these synthesis methodologies, generally, require complicated working procedures, higher reaction temperatures, high cost machineries, higher energy consumption, longer reaction times, and harmful and toxic organic reagents.…”

Copper-based non-precious metal heterogeneous catalysts for environmental remediation

“…In many cases, CuO has a higher catalytic performance at low temperature. Moreover, with the addition of FeOx [40,41] or CoOx [42], the high-temperature activity can be enhanced. Some main group elements, such as Zr [43] and Sn [44], have commonly been used to modify CuO.…”
