“…These observations indicate that the MIL‐53(Al) materials can be used as a host matrix for active Co species deposition. Moreover, the Brunauer–Emmett–Teller (BET) surface area and pore volume of Co/MIL‐53(Al) exhibit a decreasing trend with increasing cobalt loading . Micropore area, micropore volume, and external surface area of MIL‐53 (Al) samples are shown in Table .…”

Metal–organic framework of MIL‐53(Al) (Al(OH)‐[O2C‐C6H4‐CO2]) with exceptional thermal stability (as high as ≈550 °C in dynamic conditions) are synthesized via a solvothermal method, which serve as a porous host matrix of Co‐based catalysts for Fischer–Tropsch synthesis (FTS). MIL‐53(Al) shows large micropores and lattice dynamic flexibility, which make this material a promising support for active cobalt species. The as‐synthesized Co/MIL‐53(Al) catalysts with different cobalt loadings are characterized by powder X‐ray diffraction (XRD), transmission electron microscopy (TEM), Brunauer–Emmett–Teller (BET), X‐ray photoelectron spectroscopy (XPS), thermogravimetry (TG), Fourier‐transform infrared (FT‐IR) spectroscopy, and temperature programmed reduction. The results show that the immobilization of Co nanoparticles on the MIL‐53(Al) support could be beneficial to obtain novel effective catalysts for FTS. Moreover, compared with the Co/γ‐Al2O3 catalyst of the same cobalt loading, the catalytic performance of Co/MIL‐53(Al) catalyst shows higher FTS activity. Interestingly, the gasoline selectivity over the Co/MIL‐53(Al) catalyst is much higher than that of the Co/γ‐Al2O3 catalyst, close to the optimal value for maximum gasoline and diesel production.

“…Owing to superior ability for chain growth, stability, and lower activity for the WGS reaction, Co-based catalysts have also been applied to produce long-chain C 5+ hydrocarbons. Recently, a pure Co-based catalyst without promoters was reported to display high performance for both CO-FTS and CO 2 -FTS 94,95 . The Co/MIL-53(Al) catalyst was first found to exhibit 47.1% CO conversion and 68.6% selectivity to C 5+ products.…”

Recently, carbon dioxide capture and conversion, along with hydrogen from renewable resources, provide an alternative approach to synthesis of useful fuels and chemicals. People are increasingly interested in developing innovative carbon dioxide hydrogenation catalysts, and the pace of progress in this area is accelerating. Accordingly, this perspective presents current state of the art and outlook in synthesis of light olefins, dimethyl ether, liquid fuels, and alcohols through two leading hydrogenation mechanisms: methanol reaction and Fischer-Tropsch based carbon dioxide hydrogenation. The future research directions for developing new heterogeneous catalysts with transformational technologies, including 3D printing and artificial intelligence, are provided.

[136][137][138][139][140][141][142][143] Kapteijn et al: developed Co@SiO 2 catalyst by a stepwise methodology of making use of a cobalt-containing MOFs as a hard template: 144 The first step is the impregnation and hydrolysis of TEOS molecules in the pores of ZIF-67: The second step is the pyrolysis of ZIF-67@SiO 2 in N 2 resulting in the Co@C-SiO 2 catalyst. The final step is the calcination of Co@C-SiO 2 in the air to remove carbon: This preparation method results in well-dispersed cobalt nanoparticles with sizes of 5-15 nm: The cobalt loading was as high as B50 wt% with cobalt oxide reducibility of the order of 80%: Most importantly, the obtained Co@SiO 2 catalyst showed higher activity than the traditional impregnated Co/SiO 2 counterpart ( Fig.…”
