“…A comparative study of small (1 wt %) additions of Ru, Au, Pt, and Pd to an iron catalyst was carried out. Catalytic activity in the FTS reaction was found to decrease in the following order: Au–Fe > Pt–Fe > Pd–Fe > Ru–Fe . Au–Fe had the highest yield of liquid products due to the high overall material acidity.…”

Iron-based catalysts are gaining increased attention as promising and cost-effective materials for CO 2 recycling. Their properties can be tuned by careful selection of the appropriate synthesis route, substrate, and catalytic system components. For the first time, a nanostructured material consisting of heterostructures of layered ferrihydrite (Fh) and hexagonal boron nitride (h-BN) nanoparticles has been obtained. Subsequent annealing ensures a uniform distribution of Fe nanoparticles (FeNPs) on the h-BN surfaces. Small Ag additions to the system lead to a significant decrease in the average size of FeNPs, presumably due to a seeding mechanism. Catalytic tests have shown that a low Ag content has a positive effect on the catalytic activity. Stability testing has demonstrated that the catalytic properties of the Fh/BN system improve over time, as does selectivity toward high-valueadded hydrocarbons. Computational methods suggest a surface atomic configuration in which one Ag atom substitutes for one Fe atom in the (110) plane, resulting in better CO 2 adsorption.

“…Catalytic activity in the FTS reaction was found to decrease in the following order: Au−Fe > Pt−Fe > Pd−Fe > Ru−Fe. 35 Au−Fe had the highest yield of liquid products due to the high overall material acidity. It was previously demonstrated that Pt can act as both a seed and a second component of the catalytic system.…”

“…The catalytic performance of iron catalysts depends on their active phase, transition metal promoter, alkali promoter, and support [20][21][22][23][24]. It has been shown that FT synthesis over iron catalysts is a structure-sensitive reaction [1,[25][26][27], with the intrinsic reaction rate and product selectivity being functions of iron particle size. The promoted iron catalysts have, so far, shown one of the best performances in direct olefin synthesis from syngas.…”

The effect of strontium substitution in the structure of the complex oxide Gd2SrFe2O7 on the production of light olefins by CO hydrogenation was investigated. Perovskite-type oxides Gd2−xSr1+xFe2O7 (x = 0; 0.1; 0.2; 0.3; 0.4) were synthesized by sol–gel technology and characterized by XRD, Mössbauer spectroscopy, BET specific area, acidity testing, and SEM. The experimental data revealed a correlation between the state of iron atoms, acidity, and catalytic performance. It was found that with an increase in the content of Sr2+ in the perovskite phase, the basicity of the surface and the oxygen diffusion rate increased. This contributed to the CO dissociative adsorption, formation of active carbon, and its further interaction with atomic hydrogen.
