“…Mn, Zn, Zr) in the SAPO-34 structure. 404,408 Addition of transition metals and decrease in Si/Al ratio promote the reduction of the strength and density of acid sites. As a consequence, an improvement in the LO selectivity can be observed.…”

“…235 The majority of papers have addressed SAPO-34 as a zeolite component for LO synthesis via the methanol-mediated route. 408,419–422 Wang 396 et al provided the analysis of SAPO type effect on the selectivity of CO 2 hydrogenation and showed that SAPO-34 possessed the highest one towards LO fraction. At the same time, DFT calculations and catalytic experiments showed that SAPO-18 significantly enhanced the olefin-to-paraffin ratio in CO hydrogenation compared to SAPO-34 due to the suppression of hydride transfer.…”

“…25 However, Zr 4+ ions are smaller than Fe 2+ ions, which should cause the shrinkage of the crystal lattice. 36–38 The diffraction peaks will shift to a low degree when a larger ion is doped in the crystal, and shift to a high degree when a smaller ion is doped. Therefore, the XRD results confirm that the Mn and Zr ions were doped in the Fe 3 C crystal.…”

“…The optimized acidity and shape selectivity effect of the zeolite channels was achieved by physical mixing of Me-SAPO-34 (Me=Mn, Zn, Zr) with ZnO-ZrO 2 metal oxides [126]. The ZnO-ZrO 2 /Mn-SAPO-34 hybrid catalysts showed the best activity and selectivity towards light olefins: CO 2 conversion of 21.3% and olefin selectivity of 61.7%.…”

There is a large worldwide demand for light olefins (C2=–C4=), which are needed for the production of high value-added chemicals and plastics. Light olefins can be produced by petroleum processing, direct/indirect conversion of synthesis gas (CO + H2) and hydrogenation of CO2. Among these methods, catalytic hydrogenation of CO2 is the most recently studied because it could contribute to alleviating CO2 emissions into the atmosphere. However, due to thermodynamic reasons, the design of catalysts for the selective production of light olefins from CO2 presents different challenges. In this regard, the recent progress in the synthesis of nanomaterials with well-controlled morphologies and active phase dispersion has opened new perspectives for the production of light olefins. In this review, recent advances in catalyst design are presented, with emphasis on catalysts operating through the modified Fischer–Tropsch pathway. The advantages and disadvantages of olefin production from CO2 via CO or methanol-mediated reaction routes were analyzed, as well as the prospects for the design of a single catalyst for direct olefin production. Conclusions were drawn on the prospect of a new catalyst design for the production of light olefins from CO2.
