“…S7 of Supplementary Material. In line with this result, Bonura et al [23] have recently reported a superior performance in the direct CO 2 conversion to DME for a Cu-ZnO-ZrO 2 /HZSM-5 hybrid catalyst prepared by physical mixing of pre-pelletized components with respect to that prepared by grinding of the powdered single components.…”

“…As shown in Figure 7d, it has been discovered that the core where the reaction happens is mainly constituted by CuO and ZnO phases, decorated by ZrO2 crystal, where the diffraction plane (002) and (200) corresponds to CuO phase, (101) relative to ZnO phase, and (111) of ZrO2 tetragonal phase is well distinguishable [48]. Combining with the results mentioned above, we determined that the adsorption properties of H2 and CO2 could be greatly influenced by the catalyst composition, leading to the different reaction activities.…”

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.

“…Other examples of using zeolites in CO 2 conversion to bulk chemicals include CO 2 hydrogenation to form methanol in a zeolite (zeolite A) membrane reactor [ 133 ] and, by further reacting with in situ formed methanol, to produce dimethyl ether over a Cu-ZnO-ZrO 2 /H-ZSM5 catalyst. [ 134 ] In addition to industrial processes for bulk chemicals, modifi ed zeolites, acting as base catalysts, have also shown ability to promote cycloaddition of CO 2 to epoxides. Potassium exchanged zeolite X (or KX) loaded with Cs + ions have shown a high activity for adding CO 2 onto ethylene oxide to form ethylene carbonate (reaction equation shown in Figure 5 ), [ 135 ] which is a useful chemical as a plasticizer as well as an electrolyte in lithium batteries.…”

Carbon capture and storage (CCS) technologies aiming at tackling CO2 emission have attracted much attention from scientists of various backgrounds. Most CCS systems require an efficient adsorbent to remove CO2 from sources such as fossil fuels (pre‐combustion) or flue gas from power generation (post‐combustion). Research on developing efficient adsorbents with a substantial capacity, good stability and recyclability has grown rapidly in the past decade. Because of their high surface area, highly porous structure, and high stability, various nanoporous materials have been viewed as good candidates for this challenging task. Here, recent developments in several classes of nanoporous materials, such as zeolites, metal organic frameworks (MOFs), mesoporous silicas, carbon nanotubes, and organic cage frameworks, for CCS are examined and potential future directions for CCS technology are discussed. The main criteria for a sustainable CO2 adsorbent for industrial use are also rationalized. Moreover, catalytic transformations of CO2 to other chemical species using nanoporous catalysts and their potential for large scale carbon capture and utilization (CCU) processes are also discussed. Application of CCU technologies avoids any potential hazard associated with CO2 reservoirs and allows possible recovery of some running cost for CO2 capture by manufacturing valuable chemicals.
