Fe–Mn Heterojunction Modulated Electronic Environment for Enhanced CO2 Capture and In Situ Conversion

Carbon Energy, EarlyView.
Fe–Mn heterojunctions in CaO‐based dual‐functional materials create a built‐in electric field that drives electron transfer. This process generates oxygen vacancies and facilitates CO2 activation, achieving superior conversion. Waste‐derived Fe/Ca oxides enable low‐cost, thermally stable materials, offering a strategy for sustainable carbon capture and

Beyond Furnaces: Harnessing In Situ Joule Heating for Efficient C1 Catalysis

Carbon Energy, EarlyView.
Joule‐heated catalysis directly converts electrical energy into localized heat within conductive catalysts, overcoming the heat‐transfer limitations of conventional furnaces. This review summarizes recent advances in C1 molecule conversion, including CO2 methanation, reforming for hydrogen production, and HCHO/CO oxidation, while highlighting ...

Silica‐Supported Mononuclear Methyl‐Platinum Complexes Stabilized by Trimethylphosphine—Synthesis, Structure, and Reactions Under Reducing Conditions

Chemistry – A European Journal, EarlyView.
The article describes the synthesis and molecular transformations of a silica‐supported bis(phosphine)methylplatinum(II) complex under reactive (H2, CO) and inert gas atmospheres. The focus lies on the stabilizing effect of the sterically non‐demanding trimethylphosphine ligand, which alters the reactivity of the surface sites, compared to other ...

Ru Nanoparticle Supported by Mesoporous SiOx and Pillared Montmorillonite: Suppressing Catalyst Inhibition in Carbon Dioxide Hydrogenation

Chemistry – A European Journal, EarlyView.
Ru nanoparticles confined within mesoporous SiOx‐pillared montmorillonite exhibit exceptional performance for CO2 methanation. The catalyst maintains a high reaction rate even at elevated CO2 conversion while preserving high Ru mass–specific activity, overcoming typical inhibition by H2O and CO observed in conventional supported Ru catalysts.

Catalytic Oxidation of CO and VOC in Flue Gas of Coffee Roasting Machines

Chemie Ingenieur Technik, EarlyView.
Platinum‐coated cordierite monoliths effectively oxidized CO and VOC in coffee roasting exhaust with higher Pt loadings lowering light‐off temperatures. Scaled up 90 g/ft3 catalyst in a 5 kg roaster achieved 96% CO and around 78% VOC conversion at 350°C, highlighting stable operation requires flue gas temperatures ≥350°C.

On Metal Carbonyl Compounds in Catalytic Methanol Synthesis: Detection, Consequences, and Removal

Chemie Ingenieur Technik, EarlyView.
Deactivation of Cu/ZnO/Al2O3 catalysts by metal carbonyl compounds in the feed gas is a critical problem in catalytic methanol synthesis. We utilize PTR–MS to identify potential chemical sources, detect contamination in an in‐house CO gas line, and validate filter methods for removing these catalyst poisons before synthesis.

Hydroprocessing of synthetic kerosene over a non‐sulphided Ni/Al2O3 catalyst: Impact of alcohols and ketones on alkene conversion

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Synthetic jet fuel containing non‐petroleum‐derived kerosene can be produced from synthetic kerosene obtained through processes that include a hydroprocessing step. The potential use of non‐sulphided (reduced) nickel supported on alumina (Ni/Al2O3) was evaluated as an alternative to sulphided catalysts to saturate alkenes in sulphur‐free ...
