Pt–Co Single-Atom Alloy toward Furfural Hydrogenation–Rearrangement Tandem Reaction in the Aqueous Phase

ACS Catalysis, Год журнала: 2025, Номер unknown, С. 1206 - 1216

Опубликована: Янв. 6, 2025

Aqueous-phase tandem reactions, as a fundamental aspect of green chemistry, hold crucial position in the contemporary synthesis fine chemicals, wherein advancement high-performance heterogeneous catalysts remains formidable challenge. Herein, we report Pt1Con single-atom alloy (SAA) catalyst which Pt single atoms are immobilized onto surface Co nanoparticles through Pt–Co coordination. The SAA exhibits high chemoselectivity for aqueous-phase hydrogenation–rearrangement reaction furfural (FAL) to cyclopentanol (CPL) (yield: >93%, considering carbon loss), with TOF value 2257 h–1 (based on Pt). A joint investigation based dynamics, isotope-label tracing experiments, EPR, and situ FT-IR verifies five-step consecutive pathway formation CPL. Notably, during reaction, rapid exchange hydrogen would occur between activated species water solvent. Furthermore, molecule does not serve H-donor but is involved rearrangement side chain furan ring. Kinetic studies combined DFT calculations substantiate that interface sites effectively lower energy barrier cyclopentanone (CPO) hydrogenation step via facilitating activation adsorption carbonyl group, accounting largely enhanced catalytic behavior. This study sheds light highly efficient stable biomass upgrading aqueous phase.

Mass-Transfer Enhancement in the CO₂ Oxidative Dehydrogenation of Propane over GaN Supported on Zeolite Nanosheets with a Short b-Axis and Hierarchical Pores

ACS Catalysis, Год журнала: 2024, Номер 14(13), С. 10376 - 10391

The CO2 oxidative dehydrogenation of propane (CO2–ODHP) is a highly important reaction for not only producing large amounts propylene but also consuming the resource. GaN/zeolite catalysts deliver preferable activity in reaction. However, similar to Pt- and Cr-based catalysts, there are shortcomings such as poor stability coke accumulation, especially when operated at temperatures higher than 550 °C. Generally, carbon deposition one main reasons catalyst deactivation. limited mass transfer greatly aggravates deposited formation, since precursors could be removed time. In present work, we modified zeolites with short b-axis hierarchical pores, which offer shorter diffusion distance pore-rich structure enhance transfer. Thanks this enhancement, offers an initial conversion 68.0% yield 39.4% propylene, surpassing other reported data. Importantly, showed low loss rate amount carbon, was easily regenerated compared those without or pores. Density functional theory (DFT) calculations situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) confirmed that involves coupling direct reduction via reverse water–gas shift reaction, participates work sheds light on designing efficient CO2–ODHP transfer-boosted strategy and, importantly, expected provide inspiration constructing zeolite
