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: Metal-support interactions in inverse catalysts prepared by adsorbing TEOS on Co3O4 can be manipulated by varying the solvent mixture. Deposition of TEOS on Co3O4 nanoparticles in n-hexane results in the formation of silica oligomers interacting strongly with cobalt(II,III)oxide after calcination at 573 K. Modification of Co3O4 nanoparticles with TEOS in a hydrolysing environment results in a stronger interaction due to the formation of surface cobalt silicate through hydrolysis.

Summary: The role of cobalt chloride hexahydrate as a precursor of cobalt bulk catalysts was investigated for the Fischer-Tropsch reaction. Different oxygen-containing cobalt compounds were detected through in situ DRIFTS, in situ XANES, in situ XRD, and inverse TPR techniques. The reaction network of cobalt chloride transformation was discussed, taking into account the back mixing in different geometries of measuring cells. The choice of catalyst activation procedure is important for the formation of cobalt oxide and subsequent activity in the Fischer-Tropsch reaction.

Summary: In this study, a core-shell structured Na/Fe@Co bimetallic catalyst was developed to enhance CO2 conversion and selectivity of light hydrocarbons, while inhibiting CO selectivity. Characterization analyses revealed that the introduction of CoCo Prussian Blue Analog (CoCo PBA) increased the reducibility of iron oxide, accelerated the formation of iron carbide, and adjusted the surface basic properties of the catalyst. Additionally, trace Co atoms acted as a second active center in the CO2 Fischer-Tropsch synthesis process for increasing the synthesis of light hydrocarbons from CO hydrogenation. This work provides a novel core-shell structured bimetallic catalyst system for the production of light hydrocarbons, particularly light olefins, from CO2 hydrogenation.

Summary: The role of carbon deposits during Fischer-Tropsch synthesis (FTS) on cobalt catalysts is still debated. This study investigates the effects of pre-deposited composite and single carbon on cobalt catalysts in FTS. Different types of carbon deposits (atomic carbon, polymeric carbon, graphitic carbon) are identified and characterized using TPH, Raman, and XPS. Results show that the presence of pre-deposited carbon significantly affects the catalytic activity, methane selectivity, and stability of the Co-based catalysts in FTS.

Summary: Operando spectroscopic techniques were used to investigate the impact of oxygenates deposition on the deactivation of cobalt on titania Fischer-Tropsch catalysts under high pressure. It was found that catalysts prepared via impregnation had more and heavier carboxylates, likely due to higher olefin content in the products, leading to increased formation of oxygenates. Gas chromatography/infrared spectroscopy data indicated that the surface carboxylate species were not involved in catalyst deactivation, serving as spectator species on the titania support.

Summary: The use of zeolite-containing Co catalysts in liquid hydrocarbon transformations during Fischer-Tropsch synthesis demonstrated a decrease in the average molecular weight of the products without increasing methane selectivity. The introduction of zeolites cleared the catalyst pore system of heavier hydrocarbons, suggesting a potential role in controlling product composition over hybrid catalysts.

Summary: Through IR spectroscopy and DFT calculations, it has been discovered that in the Fischer-Tropsch reaction, Mn promotes a silica-supported Co catalyst with a MnO layer covering the Co surface, activating adsorbed CO through reaction with an oxygen vacancy. This results in higher activity, higher CHx coverage, increased C5+ selectivity, and decreased CH4 selectivity. Increasing pressure amplifies the selectivity differences. However, above around 4 bar, the addition of Mn decreases C5+ selectivity, possibly due to its promotion of C-O bond dissociation but not chain growth. Migration of formed monomers for chain growth on the Co surface may be hindered by high CO coverage, especially at high pressure.

Summary: The Fischer-Tropsch (FT) process is a promising method for producing liquid fuels and valuable chemicals through CO hydrogenation. Catalyst activity and product selectivity are influenced by parameters such as support and promoters, which affect metal-support interaction, crystallite size, and more. This paper reviews the history of the FT process, the impact of different supports and promoters on cobalt-based catalyst performance, and the importance of proper reactor design for handling the heat of the exothermic reaction.

Summary: In this study, indium (In) ions were introduced into flexible Cu2ZnSn(S,Se)(4) (CZTSSe) solar cells to modify the back interface and passivate deep level defects in CZTSSe bulk. The results showed that In doping effectively inhibited the formation of secondary phase and V-Sn defects, decreased the barrier height at the back interface, passivated deep level defects in CZTSSe bulk, increased carrier concentration, and significantly reduced the V-OC deficit. Eventually, a flexible CZTSSe solar cell with a power conversion efficiency of 10.01% was achieved. This synergistic strategy of interface modification and bulk defects passivation through In incorporation provides a new approach for fabricating efficient flexible kesterite-based solar cells.

The Nafion modifier suppresses the hydrogen evolution reaction, increases CO2 concentration and mass transfer process, and activates CO2 molecule to enhance C2 product generation. As a result, the selectivity of the hydrogen evolution reaction is reduced and the efficiency of C2 products is significantly improved.

Summary: Direct growth of redox-active noble metals and rational design of multifunctional electrochemical active materials play crucial roles in developing novel electrode materials for energy storage devices. In this regard, silver (Ag) has attracted great attention in the design of efficient electrodes. The construction of multifaceted heterostructure cobalt-iron hydroxide (CFOH) nanowires (NWs)@nickel cobalt manganese hydroxides and/or hydrate (NCMOH) nanosheets (NSs) on the Ag-deposited nickel foam and carbon cloth (i.e., Ag/ NF and Ag/CC) substrates is reported. The as-fabricated Ag@CFOH@NCMOH/NF electrode delivered superior areal capacity value of 2081.9 μA h cm-2 at 5 mA cm-2. Moreover, as-assembled hybrid cell based on NF (HC/NF) device exhibited remarkable areal capacity value of 1.82 mA h cm-2 at 5 mA cm-2 with excellent rate capability of 74.77% even at 70 mA cm-2. Furthermore, HC/NF device achieved maximum energy and power densities of 1.39 mW h cm-2 and 42.35 mW cm-2, respectively. To verify practical applicability, both devices were also tested to serve as a self-charging station for various portable electronic devices.
