Carbon dioxide (CO 2 ) hydrogenation to liquid fuels including gasoline, jet fuel, diesel, methanol, ethanol, and other higher alcohols via heterogeneous catalysis, using renewable energy, not only effectively alleviates environmental problems caused by massive CO 2 emissions, but also reduces our excessive dependence on fossil fuels. In this Outlook, we review the latest development in the design of novel and very promising heterogeneous catalysts for direct CO 2 hydrogenation to methanol, liquid hydrocarbons, and higher alcohols. Compared with methanol production, the synthesis of products with two or more carbons (C 2+ ) faces greater challenges. Highly efficient synthesis of C 2+ products from CO 2 hydrogenation can be achieved by a reaction coupling strategy that first converts CO 2 to carbon monoxide or methanol and then conducts a C–C coupling reaction over a bifunctional/multifunctional catalyst. Apart from the catalytic performance, unique catalyst design ideas, and structure–performance relationship, we also discuss current challenges in catalyst development and perspectives for industrial applications.

“…It can be overcome by the use of selective support. Metal oxides like Al2O3 [11], ZrO2 [12], SiO2 [13], carbon materials [14,15], CeO2 [16], TiO2 [17], and MnO2 [18] were used as supports to deposit the active metals for the study of CO2 catalytic hydrogenation.…”

A series of CeO2 supported Cu, Co, and Ni catalysts have been synthesized by the wetimpregnation method for CO2 thermo-catalytic hydrogenation from 200 -400 °C in the fixed bed reactor. All catalysts were characterized by XRD, N2-isotherms, and H2 temperature-programmed reduction. XRD results have suggested that the incorporated Cu, Co, and Ni have uniformly distributed on the CeO2 surface, N2-isotherm analysis confirmed that the pores of CeO2 were blocked by incorporated metals and H2-TPR indicated strong interaction between active metal and CeO2. The CO2 consumption rate and product selectivity depend on the type of active metal on CeO2 and reaction temperature. The order of CO2 consumption rate for 5wt% catalysts was 5Ni/CeO2 > 5Co/CeO2 > 5Cu/CeO2 at 400 °C. The high CO2 consumption rate for 5Ni/CeO2 was attributed to the presence of more number of active metallic Ni during the reaction which dissociated H2 molecule to H-atoms. The formed H-atoms reacted with active CO2 molecule and formed CH4 with 100% selectivity.

“…For bimetallic catalysts, the refined biofuel percentages obtained from PF1, PF2, and PF3 were 74%, 66%, and 82%, respectively (see Figure 4). It should be noted that bimetallic catalysts showed a lower refined-biofuel yield than monometallic catalyst since the Fe catalyst increases olefin hydrocarbons including ethylene, propylene and butadiene better than refined-biofuel [13]. Crude biofuels obtained from hydrocracking reaction could be classified into three kinds depending on their boiling point: (i) green gasoline, (ii) green kerosene, and (iii) green diesel, as illustrated in Figure 5.…”

Biofuels of Green Diesel–Kerosene–Gasoline Production from Palm Oil: Effect of Palladium Cooperated with Second Metal on Hydrocracking Reaction

In this work, two kinds of catalyst called monometallic Palladium (Pd) and a bimetallic of Pd-Iron (Fe) were synthesised using aluminum oxide (Al 2 O 3 ) as the supported material via the wet impregnate method. A monometallic catalyst (0.5% Pd/Al 2 O 3 ) named Pd cat was used as control. For the bimetallic catalyst, ratios of Pd to Fe were varied, and included 0.38% Pd-0.12% Fe (PF1), 0.25% Pd-0.25% Fe (PF2), and 0.12% Pd-0.38% Fe (PF3). The catalysts were characterised to investigate physical properties such as the surface area, pore size, porosity, and pore size distribution including their composition by Brunauer-Emmett-Teller (BET) surface area, Scanning Electron Microscopy (SEM), and X-Ray Diffraction (XRD). Subsequently, all catalysts were applied for biofuels production in terms of green diesel/kerosene/gasoline from palm oil via a hydrocracking reaction. The results showed that the loading of Fe to Pd/Al 2 O 3 could improve the active surface area, porosity, and pore diameter. Considering the catalytic efficiency for the hydrocracking reaction, the highest crude biofuel yield (94.00%) was obtained in the presence of PF3 catalyst, while Pd cat provided the highest refined biofuel yield (86.00%). The largest proportion of biofuel production was green diesel (50.00-62.02%) followed by green kerosene (31.71-43.02%) and green gasoline (6.10-8.11%), respectively. It was clearly shown that the Pd-Fe bimetallic and Pd monometallic catalysts showed potential for use as chemical catalysts in hydrocracking reactions for biofuel production.
