Laser Synthesis in Liquid Induced Lattice Distortion in PtFeSn/Activated Carbon for Enhanced Methylcyclohexane Dehydrogenation. [PDF]

Small Methods
A Pt‐Fe‐Sn alloy catalyst supported on activated carbon is synthesized via laser synthesis in liquid, introducing lattice distortions that enhance active site exposure and toluene desorption. The catalyst achieves a hydrogen evolution rate of 2625 mmol gPt⁻¹ min⁻¹ with 99.96% selectivity and excellent stability, offering a promising strategy for ...

Ultrasound–Calcination Synergistic Control of (Ce, La)PO4 Catalyst Structure for Enhanced Low‐Temperature NH3‐SCR Performance

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In this study, (Ce, La)PO4 catalysts were synthesized via an ultrasound‐assisted method. The effects of ultrasound duration and calcination temperature on the low‐temperature NH3‐SCR performance were systematically investigated. The results indicated that the (Ce, La)PO4 catalyst prepared with an ultrasound treatment time of 20 min and a ...

Entropy‐Controlled Exsolution of Highly Dispersed Nickel‐Based Active Metals From Spinel Oxide via Optimizing Metal‐Support Interaction for Dry Reforming of Methane

Carbon Energy, EarlyView.
The incorporation of transition‐metal elements into spinel oxides results in enhanced configurational entropy and increased metal‐support interaction, which continuously modulate the exsolution of nickel‐based active metal. The highly dispersed nickel‐based metal catalyst, formed through the entropy‐controlled strategy, demonstrates remarkable activity

A study of Ni‐Co/CeO2 catalyst derived from metal–organic framework for dry reforming of methane

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The efficacy of cobalt‐doped, MOF‐derived catalysts for dry reforming of methane (DRM) was examined. The focus was on the influence of varying nickel and cobalt molar ratios on catalytic performance. Three catalysts with Ni:Co ratios of 1:1, 1:0.5, and 0.5:1, were synthesized and tested with cerium oxide as a constant support. The DRM reaction
