“…Combining Table 1 with Fig. 2, it is concluded that the higher S Cu over CZA catalyst can promote the catalytic performance of the catalyst in methanol synthesis from syngas, which is in agreement with some observations reported [26,27].…”

“…H 2 -TPR characterization indicates that with the introduction of the surfactant in the course of preparing the binary matrix, the reduction temperature at peak maximum of resultant CZA catalyst shifts to higher temperature. It was reported [10,26] that the shift of the reduction temperature related to the interaction between CuO and ZnO lattices in CZA catalyst, in which the shift to higher reduction temperature in H 2 -TPR profile implied a stronger interaction between the two lattices. In Fig.…”

“…A study of the catalytic activity of the CuO‐ZnO‐Al 2 O 3 /HZSM‐5 nanocatalysts prepared by impregnation and co‐precipitation‐physically mixing and combined co‐precipitation‐ultrasound methods in the syngas conversion to DME has shown that employing ultrasound treatment has a pronounced influence on the catalyst hydrogenation function and, consequently, the DME synthesis performance . The Cu/ZnO/Al 2 O 3 catalysts synthesized by gel‐network co‐precipitation exhibit high catalytic properties in CO 2 hydrogenation to methanol due to optimized structural properties, particularly the surface area and the crystallite size formed during the preparation process …”

Comparative study of magnesia‐supported highly‐dispersed CuO solids prepared by different methods in CO oxidation

Magnesia‐supported highly‐dispersed CuO solids were prepared by impregnation and mechanical mixing of CuO nanopowders with MgO. Additionally, ultrasound and mechanochemical treatment of CuO nanopowders mixed with MgO was performed. TEM and XRD studies indicate that the size of the CuO nanoparticles in solids depends on the method of preparation. Catalytic tests of these solids in the CO oxidation show that varying the method of catalyst preparation changes the temperature of the 100 % conversion CO by more than 130 °C. Fabrication of the CuO‐MgO catalysts via an easy mixing process using CuO nanopowder and cubic MgO gives the most active catalyst. Mechanochemical and/or ultrasound treatments lead to catalyst deactivation. Our results show that method of the catalyst preparation influences the catalyst performance mainly through varying the CuO nanoparticle size and CuO‐support interaction.
