“…The BE value of ca. 181.8 eV measured for Zr 3d 5/2 indicates the presence of ZrO 2 with an oxidation state of +4 [43]. It was also reported that the BE of Zr 4+ species in pure ZrO 2 is around 182.6 eV [44]; slightly lower values were observed in case of CuZr samples compared to that of stoichiometric ZrO 2 .…”

Mesoporous CuO-ZrO 2 catalysts were prepared and calcined at 500˝C. The performance of the synthesized catalysts for benzylation of benzene using benzyl chloride was studied. The bare support (macroporous ZrO 2 ) offered 45% benzyl chloride conversion after reaction time of 10 h at 75˝C. Significant increase in benzyl chloride conversion (98%) was observed after CuO loading (10 wt. %) on porous ZrO 2 support. The conversion was decreased to 80% with increase of CuO loading to 20 wt. %. Different characterization techniques (XRD, Raman, diffuse reflectance UV-vis, N 2 -physisorption, H 2 -TPR, XPS and acidity measurements) were used to evaluate physico-chemical properties of CuO-ZrO 2 catalysts; the results showed that the surface and structural characteristics of the ZrO 2 phase as well as the interaction between CuO-ZrO 2 species depend strongly on the CuO content. The results also indicated that ZrO 2 support was comprised of monoclinic and tetragonal phases with macropores. An increase of the volume of monoclinic ZrO 2 phase was observed after impregnation of 10 wt. % of CuO; however, stabilization of tetragonal ZrO 2 phase was noticed after loading of 20 wt. % CuO. The presence of low-angle XRD peaks indicates that mesoscopic order is preserved in the calcined CuO-ZrO 2 catalysts. XRD reflections due to CuO phase were not observed in case of 10 wt. % CuO supported ZrO 2 sample; in contrast, the presence of crystalline CuO phase was observed in 20 wt. % CuO supported ZrO 2 sample. The mesoporous 10 wt. % CuO supported ZrO 2 catalyst showed stable catalytic activity for several reaction cycles. The observed high catalytic activity of this catalyst could be attributed to the presence of a higher number of dispersed interactive CuO (Cu 2+ -O-Zr 4+ ) species, easy reducibility, and greater degree of accessible surface Lewis acid sites.

“…Chen et al [36][37][38][39][40] suggest that CO is formed from decomposition of format intermediate, deduced from unification of hydrogen (H 2 ) with CO 2 . As well as, Sloczynski et al [41] indicate that CO may be formed from decomposition of methanol, whereas the reverse-water-gas-shift mechanism can explain directly the CO formation as the major by product.…”

-Climate change and global warming have become a challenging issue affecting not only humanity but also flora and fauna due to an intense increase of CO 2 emission in the atmosphere which has gradually led to amplification in the average global temperature. Hence, a number of mechanisms have been promoted to diminish the atmospheric commutation of carbon dioxide. One of the well-known techniques is Carbon Capture and Storage (CCS) which mechanism is based on capture and storage vast quantities of CO 2 , as well as Carbon Capture and Utilization (CCU) which mechanism is based on CO 2 conversion to liquid fuels (e.g. methanol, hydrocarbons, carbonate, propylene, dimethyl ether, ethylene, etc.). Particularly, methanol (CH 3 OH) is a key feedstock for industrial chemicals, which further can be converted into high molecular alternative liquid fuels. In this regard, hydrogenation of CO 2 is one of the promising, effectual and economic techniques for utilization of CO 2 emission. Nevertheless, the reduction/activation of CO 2 into useful liquid products is a scientifically challenging issue due to the complexities associated with its high stability. Thus, various catalysts have been applied to reduce the activation energy of the hydrogenation process and transform CO 2 into value-added products. Thereby, this review article highlights the progress and the recent advances of research investigation in Cu and Fe-based catalytic conversion of CO 2 , reaction mechanisms, catalytic reactivity, and influence of operating parameters on product efficiency.

“…were adopted, and the positive effects of them have also been documented [15][16][17][18][19][20][21][22][23][24][25][26]. Additionally, the composition, texture of catalysts, and dispersion of metal and oxide phases on the catalysts are also greatly associated with their activities, which can be obtained using a variety of preparation methods [16,23,[27][28][29][30][31] Arena et al [16,21,28,32] used reverse co-precipitation under ultrasound irradiation to obtain a series of Cu-ZnO/ZrO2 catalysts with a remarkable total surface area and high dispersion. Deng et al [7,12] and Bonura et al [32] adopted the oxalate-co-precipitated technique to enhance the catalyst activity, whereas Guo et al [29,33] found that the combustion method was a simple, fast, and valuable route.…”

“…The citrate method was also an important method for preparing CZZ catalysts investigated by Karelovic et al [34]. It is known that the citrate method provides solids with high surface areas at relatively low calcination temperatures [20,21,34]. In addition, a homogeneous gel (containing the metal precursors) could be formed by complexing dissolved nitrate salts with citric acid consisting in the initial formation.…”

Catalytic Hydrogenation of CO2 to Methanol: Study of Synergistic Effect on Adsorption Properties of CO2 and H2 in CuO/ZnO/ZrO2 System

et al. 2015

A series of CuO/ZnO/ZrO2 (CZZ) catalysts with different CuO/ZnO weight ratios have been synthesized by citrate method and tested in the catalytic hydrogenation of CO2 to methanol. Experimental results showed that the catalyst with the lowest CuO/ZnO weight ratio of 2/7 exhibited the best catalytic performance with a CO2 conversion of 32.9%, 45.8% methanol selectivity, and a process delivery of 193.9 gMeOH·kgcat. A synergetic effect is found by systematic temperature-programmed-desorption (TPD) studies. Comparing with single and di-component systems, the interaction via different components in a CZZ system provides additional active sites to adsorb more H2 and CO2 in the low temperature range, resulting in higher weight time yield (WTY) of methanol.
