Selective Hydrogenation of Formamide to Methanol Over Supported Platinum Catalysts

Angewandte Chemie International Edition, EarlyView.
Amine–CO2 adducts can be hydrogenated to formamides and subsequently to methanol under mild conditions (<150°C), establishing an integrated CO2 capture‐and‐conversion route in a heterogeneous system that directly links amine sorbent cycling with methanol synthesis.

Initiation: A Critical Step for High Activity and Stability in Ni‐Based Methane Dry Reforming Catalysts Supported on θ‐Al2O3

Angewandte Chemie, Volume 138, Issue 19, 4 May 2026.
A well‐defined Ni/θ‐Al2O3 catalyst prepared by surface organometallic chemistry exhibits sharp temperature‐dependent behavior in dry reforming of methane. At 850°C, a dynamic induction process forms a transient carbide‐like NiCx phase that enables continuous carbon removal and coke resistance, whereas at 800°C incomplete carbon insertion leads to ...

Systematic Hydrogen‐Bond Manipulations To Establish Polysaccharide Structure–Property Correlations [PDF]

, 2019
A dense hydrogen‐bond network is responsible for the mechanical and structural properties of polysaccharides. Random derivatization alters the properties of the bulk material by disrupting the hydrogen bonds, but obstructs detailed structure–function ...

Hydrogenolysis of glycerol over Pt/C catalyst in combination with alkali metal hydroxides

Open Chemistry, 2016
The hydrogenolysis of glycerol was performed over a Pt/C catalyst in combination with several alkali metal hydroxides and their salts. LiOH was found to be an effective promoter for the selective hydrogenolysis of glycerol to 1,2-propanediol.

Synthesis of Quinazoline and Quinazolinone Derivatives via Ligand-Promoted Ruthenium-Catalyzed Dehydrogenative and Deaminative Coupling Reaction of 2-Aminophenyl Ketones and 2-Aminobenzamides with Amines [PDF]

, 2019
The in situ formed ruthenium catalytic system ([Ru]/L) was found to be highly selective for the dehydrogenative coupling reaction of 2-aminophenyl ketones with amines to form quinazoline products.

Post‐Shaping Over‐Impregnation: A Facile Strategy for Pt‐KL Catalysts With Ultrahigh Metal Dispersion and Enhanced Aromatization Performance

Carbon and Hydrogen, EarlyView.
A scalable post‐shaping strategy achieves precise Pt localization within KL zeolite, where optimized spatial distribution minimizes diffusion barriers to deliver superior n‐hexane aromatization activity, selectivity, and stability. ABSTRACT The precise localization of metal clusters within zeolite frameworks is critical for the aromatization catalysis.

Non-thermal plasma-assisted hydrogenolysis of polyethylene to light hydrocarbons

Catalysis Communications, 2021
Upcycling is an attractive approach for valorization of waste plastics to valuable chemicals. Here we report the first case study of non-thermal plasma-assisted hydrogenolysis of high-density polyethylene (HDPE) to C1-C3 hydrocarbons.

Tuning the Geometric and Electronic Structures in PtMn/SiO2 Catalysts via Oxygen Plasma Treatment for Enhanced Propane Dehydrogenation

Carbon and Hydrogen, EarlyView.
Oxygen plasma treatment promotes Pt dispersion, reducing the average Pt particle size of PtMn catalyst from 2.7 to 1.2 nm, and increases the electron cloud density of Pt. The optimized catalyst exhibits excellent mass‐normalized activity (171 molC3H8·gPt−1·h−1) and an ultralow deactivation rate constant, outperforming most reported Pt‐based catalysts ...
