“…The same group continues to explore the magnetic field-assisted CO 2 conversion over the Cu-Fe/ZSM-5 catalyst and observes a similar enhancement. 228 These results substantiate the viability of the incorporation of magnetic field into thermocatalytic CO 2 conversion. Future studies should primarily focus on advancing the knowledge of the correlation of magnetic field and surface chemistry, which offers a guideline to engineer catalytic materials and the optimization of reaction system.…”

The utilization of fossil fuels has enabled an unprecedented era of prosperity and advancement of well-being for human society. However, the associated increase in anthropogenic carbon dioxide (CO2) emissions can negatively affect global temperatures and ocean acidity. Moreover, fossil fuels are a limited resource and their depletion will ultimately force one to seek alternative carbon sources to maintain a sustainable economy. Converting CO2 into value-added chemicals and fuels, using renewable energy, is one of the promising approaches in this regard. Major advances in energy-efficient CO2 conversion can potentially alleviate CO2 emissions, reduce the dependence on nonrenewable resources, and minimize the environmental impacts from the portions of fossil fuels displaced. Methanol (CH3OH) is an important chemical feedstock and can be used as a fuel for internal combustion engines and fuel cells, as well as a platform molecule for the production of chemicals and fuels. As one of the promising approaches, thermocatalytic CO2 hydrogenation to CH3OH via heterogeneous catalysis has attracted great attention in the past decades. Major progress has been made in the development of various catalysts including metals, metal oxides, and intermetallic compounds. In addition, efforts are also put forth to define catalyst structures in nanoscale by taking advantage of nanostructured materials, which enables the tuning of the catalyst composition and modulation of surface structures and potentially endows more promising catalytic performance in comparison to the bulk materials prepared by traditional methods. Despite these achievements, significant challenges still exist in developing robust catalysts with good catalytic performance and long-term stability. In this review, we will provide a comprehensive overview of the recent advances in this area, especially focusing on structure–activity relationship, as well as the importance of combining catalytic measurements, in situ characterization, and theoretical studies in understanding reaction mechanisms and identifying key descriptors for designing improved catalysts.

“…All CU- x -300 samples possess a large Brunauer–Emmett–Teller (BET) surface area (>290 m 2 ·g –1 ). Such good porosity would facilitate mass transfer in heterogeneous catalysis. ,− We also measured the Cu and Zr contents of CU- x -300 samples by using an ICP-AES (Table ). The actual Cu/Zr molar ratios are slightly higher than the theoretical ones.…”

In Situ Generation of the Cu@3D-ZrO_x Framework Catalyst for Selective Methanol Synthesis from CO₂/H₂

Cu-based catalysts have been widely studied for direct hydrogenation of CO 2 to methanol. Their activities quite depend on the amount of exposed active sites (e.g., Cu-oxide interfaces), which can be tuned by the particle size as well as porosity. Here, we report an active, selective, and stable Cu@ZrO x catalyst with a three-dimensional (3D) porous framework structure via the in situ reconstruction of size-confined Cu@UiO-66. The optimized CU-0.5-300 catalyst shows a high methanol selectivity of 78.8% at a conversion of 13.1% at 260 °C, 4.5 MPa, giving a methanol space-time yield of 796 g•kg cat −1•h −1 . It also shows long-term stability for 105 h in a time-onstream test. Such good performance benefits from abundant Cu−ZrO x interfaces and a stable 3D ZrO x framework. During the reaction, ZrO x species in situ evolves from the unstable Zr-oxide cluster (the building unit of UiO-66) or amorphous ZrO 2 to a stable tetragonal ZrO 2 phase, but strong metal−support interaction (SMSI) at Cu−ZrO x interfaces retains. The SMSI enables the formation of Cu + at the ZrO 2 surface, which is strongly associated with the active sites for methanol synthesis. In situ diffuse-reflectance infrared Fourier transform spectroscopy studies reveal methanol synthesis which follows a HCOO-intermediated pathway. It is believed that this work provides an "in situ reconstruction" strategy to fabricate a practical Cu@ZrO x framework catalyst for methanol production.

“…472 To improve methanol production from carbon dioxide at low temperatures, magnetic field-assisted reactors are being investigated, showing positive effects on CO 2 conversion and selectivity towards methanol. 187,473 The presence of carbonproducing reactants and/or intermediates and/or products is another trivial challenge for some of these reactions (e.g., DRM) as mentioned above. Even if catalyst design is the key to overcome such a problem, the operating conditions must be properly chosen to find the optimum between yield and catalyst deactivation, to maximize the profitability of the process.…”
