Summary: Ru-Co/Al2O3 and Ru-Fe/Al2O3 catalysts prepared by reduction-deposition method exhibit high activity in Fischer-Tropsch Synthesis, showing different conversion rates and product selectivity. The interaction between Ru and Co in Ru-Co/Al2O3 enhances the activity, while Ru-Fe/Al2O3 displays superior initial performance but declines over time, with less enriched products compared to Ru/Al2O3.

Summary: Sodium-promoted monoclinic zirconia supported ruthenium catalysts showed enhanced selectivity to CO and chain growth products, and reduced methane selectivity during CO2 hydrogenation. The sodium promotion increased the catalyst basicity, facilitated CO2 adsorption, and inhibited methanation. The suppression of excessive hydrogenation increased the chain growth probability. Sodium was in contact with ruthenium, as indicated by the reduction behavior and XANES spectra. No evidence of electron charge transfer promoting effect was observed.

Summary: Selective reactions that combine H-2, CO, and organic electrophiles to form hydrogenated C-3 and C-4 carbon chains have been reported. These reactions involve CO homologation mediated by [W(CO)(6)] and an aluminum(I) reductant, followed by functionalization and hydrogenation of the chain ends. Kinetics and DFT calculations provide insight into the hydrogenation of a metal-locarbene intermediate, revealing the controlled production of well-defined products with desired chain length and functionality.

Summary: The increase in global population and industrialization has led to a significant rise in biogenic wastes. These wastes have the potential to be a valuable source of energy as an alternative to nonrenewable fossil fuels. Thermochemical technologies offer effective solutions for converting waste biomass into biofuels and valuable biochemicals. However, non-catalytic thermochemical conversion technologies face challenges such as low yields, undesired byproducts, and higher levels of heteroatoms that impact the quality of the final fuel products. This review article explores innovative catalytic approaches to address these challenges and evaluates the impact of catalysts on the production of biofuels and biochemicals through various thermochemical conversion technologies.

Summary: The kinetics of the transformation of metallic Fe to the active Fe carbide phase at the start of the Fischer-Tropsch (FT) reaction were studied. The diffusion rates of C atoms going in or out of the lattice were determined using C-13-labeled synthesis gas. It was found that in the initial stages, C diffused rapidly into the lattice, and the FT reaction started during this period. When reaching steady state, the diffusion rates of C in and out of the lattice converged, and the FT reaction continued via two parallel reaction mechanisms. The outer layers of the Fe carbide were involved in hydrocarbon formation via a slow reaction, contributing to around 10% of the total activity.

Summary: This study reveals that the performance of iron-based catalysts can be modified by simply changing the percentage of Fe(II)/Fe(III) in the raw materials. The catalysts prepared by FeCl2·4H2O exhibit higher CO conversion, lower methane selectivity, and higher C-2-C-4 olefin-to-paraffin ratio, which can be mainly attributed to the higher Fe2+ content in the unreduced state.

Summary: The use of a sn-containing binary co-catalyst enhances the performance of Pd in the photocatalytic production of green hydrogen from methanol:water mixtures. A Pd:Sn molar ratio of 1:1 leads to an outstanding enhancement of activity under UV, visible and sunlight illumination, with a quantum efficiency value of 4 % in the latter case. The interaction between Pd metal nanoparticles and Sn oxo-hydroxyde nanoentities results in an electronic modification of both components.

Summary: Structure-sensitive catalyzed reactions can be influenced by several parameters. It has been established that Pd-C species are responsible for the behavior of Pd nanoparticles in a butadiene hydrogenation reaction. Experimental evidence suggests that subsurface Pd hydride species govern the reactivity of this reaction, and the formation/decomposition of PdHx species is sensitive to the dimensions of Pd nanoparticle aggregates, which controls the selectivity in this process. High-energy X-ray diffraction (HEXRD) is the main methodology used to determine this reaction mechanism.

Summary: In recent years, the combination of thermal and photochemical contributions has provided interesting opportunities for solar upgrading of catalytic processes. Photothermal catalysis acts at the interface between purely photochemical and classical thermal catalysis, activating reactive molecules at moderate temperatures and with higher reaction rates. Although photothermal-catalytic CO2 reduction processes are still in their infancy, they have gained a great deal of attention. This article aims to provide an overview of the principles and applications of photothermal catalysis, focusing on the conversion of CO2 into useful molecules.

Summary: A series of catalysts with increasing amounts of Niobium were prepared using Pd as a co-catalyst and a high surface area titania support. The samples exhibited a consistent Pd particle size of approximately 4.6 nm, and Niobium was found to be present in the pores of anatase without affecting the primary particle size of the main oxide. The activity of the samples in hydrogen production under UV and visible illumination was tested and measured, showing that the optimal catalyst contained 1 mol. % of Niobium and demonstrated a quantum efficiency value of 2.8%.

Summary: This research analyzed the impact of adding zirconium oxide to titanium oxide-supported gold systems on photocatalytic hydrogen production. The highest activity was achieved with a 1.75 mol.% zirconium oxide, showing a quantum efficiency close to 1.9% under sunlight, which was over two orders of magnitude improvement compared to the original titanium system. The addition of zirconium influenced the recombination of charge carriers and boosted photoactivity through the interaction between gold and zirconium.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
