Morphology effect of ZnO support on the performance of Cu toward methanol production from CO2 hydrogenation

Morphology Effects of CeO2 Nanomaterials on the Catalytic Combustion of Toluene: A Combined Kinetics and Diffuse Reflectance Infrared Fourier Transform Spectroscopy Study

“…Heterogeneous catalysis generally involves the cleavage and formation of chemical bonds for the reactant and the product on the surface of a catalyst, and these elementary steps could be rationally expected to be closely associated with the coordination environment or active sites of the catalyst surface. − Catalyst morphology is a significant tool to investigate these impacts on heterogeneous catalysis because a morphology-controllable catalyst could expose specific crystal planes, which had different coordination environments. ,,− Therefore, morphology effects have been paid much attention for investigating heterogeneous catalysis.…”

The effect of small addition of copper on the growth process, structure, surface charge and adsorption properties of ZnO films in the pyrolysis of dithiocarbamates

“…[3][4][5][6][7][8][9][10][11] In addition, ZnO and ZnS are increasingly being used to obtain unique nanoscale structures for solar energy, water decomposition, etc. [12][13][14][15] In recent years, the Cu decorated ZnO films or nanorod arrays have emerged as one of the most economical multifunctional semiconducting materials for the chemical conversion of greenhouse gas CO 2 into value-added methanol, [16][17][18][19] compositions with enhanced photocatalytic and antibacterial performances, 9,20,21 magnetic alloys, 22 sensitive layers for hazardous gases, 23 high performance transparent electrodes, [24][25][26] unassisted solar water splitting, 27 enhancement of visible luminescence and photocatalytic activity. 23,28,29 In all these applications, it is the surface properties of functional structures based on ZnO:Cu that play a decisive role.…”

Oriented Isomorphous Substitution: An Efficient and Alternative Route to Fabricate the Zn Rich Phase Pure (Cu1−x,Znx)2(OH)2CO3 Precursor Catalyst for Methanol Synthesis

“…reported that filament‐like ZnO supported Cu lead to the formation of excess oxygen vacancies at the interface facilitating the activation of CO 2 by adsorption process. In addition, the morphology of the Cu/ZnO catalyst was reported to influence the size, dispersion state and also the reducibility of the CuO domains . The pure Cu 2 (OH) 2 CO 3 retains its lamellar structure even upon calcination, while the IS x C samples retain their regular needle‐like structure and with increase in Zn content the width of the needle‐like structure is also gradually reduced.…”

“…In addition, the morphology of the Cu/ZnO catalyst was reported to influence the size, dispersion state and also the reducibility of the CuO domains. [45][46][47] The pure Cu 2 (OH) 2 CO 3 retains its lamellar structure even upon calcination, while the ISxC samples retain their regular needle-like structure and with increase in Zn content the width of the needle-like structure is also gradually reduced. Further, it can be found that there is more intimate interface between CuO and ZnO in the catalyst, indicating the improved synergistic interaction between them, which is beneficial for the improvement of catalytic activity.…”
