CeO₂/CuO/3DOM SiO₂ catalysts with very high efficiency and stability for CO oxidation

Abstract

Based on the urgent need for high active and stabile catalyst for CO conversion at low temperature, a CeO2/CuO/SiO2 ordered macroporous composite catalyst with 3DOM structure was prepared. The 3DOM...

Efficient and Stable Ni/ZSM-5@MCM-41 Catalyst for CO2 Methanation

“…The Ni/ZSM-5@MCM-41 catalyst detected the intermediate species of formate and the characteristic peak of adsorbed CO at 2176 cm –1 during the reaction process, so it was speculated that the reaction took place through the reaction pathway of formate and CO . Two main species, carbonate and bicarbonate, can be seen on the IR spectrum below 200 °C.…”

Construction of cerium-based oxide catalysts with abundant defects/vacancies and their application to catalytic elimination of air pollutants

“…As such, it is important to reduce and eliminate CO. 85 Compared with other CO removal technologies, catalytic oxidation has several advantages, such as low energy consumption, high processing capacity, and low secondary pollution. 86 Typical catalysts for CO oxidation are based on noble metals ( e.g. , Au, Pt, or Pd) or transition metals ( e.g.…”

Metal–organic framework-derived hierarchical porous N/Co-doped carbon-supported sponge-like Pd–SnO2 nanostructures for low-temperature CO oxidation

“…[1][2][3] Limitless efforts to solve these issues lie in developing green energy technologies (i.e., fuel cells, 4 batteries, 5 and water splitting 6,7 ) and gas conversion reactions. [8][9][10] CO Oxid is formed during heterogeneous catalysis electrochemically, 11,12 or thermally, [13][14][15][16] but the latter is feasible for large-scale applications. Pd-based catalysts are among the most active catalysts for thermal CO Oxid , however, the high cost and earth-rarity of Pd are critical barriers.…”
