Progress in palladium-based bimetallic catalysts for lean methane combustion: Towards harsh industrial applications

The Innovation Materials, Год журнала: 2025, Номер unknown, С. 100116 - 100116

Опубликована: Янв. 1, 2025

<p>Significant volumes of lean methane (0.1–1.0 vol%) are released untreated into the atmosphere during industrial operations, contributing to greenhouse effect and energy wastage. Catalytic combustion presents a promising avenue mitigate these emissions. Depending on their active components, catalytic systems predominantly categorized noble metal-based non-noble catalysts, with palladium (Pd)-based catalysts recognized for superior low-temperature oxidation activity. Nevertheless, enhancing thermal stability Pd remains challenging, complicated by impurities such as H₂O, SO₂ H₂S in stream, which can cause catalyst poisoning deactivation. Recent research has focused design Pd-based bimetallic offering improved stability, activity, resistance harsh conditions. This review examines advancements improving deactivation combustion, covering site characterization, dispersion metal-support interactions, role auxiliary metals, structural modulation strategies. It also investigates impact environments performance, focusing mechanisms mitigation Ultimately, this identifies current trends challenges demanding applications. By providing insights enhanced poisoning, aims guide development that meet demands.</p>

Hydrophobic Modification of ZSM-5-Encapsulated Uniform Pt Nanoparticles for Catalytic Oxidation of Volatile Organic Compounds

ACS Applied Nano Materials, Год журнала: 2022, Номер 5(3), С. 3374 - 3385

Опубликована: Фев. 23, 2022

Zeolite-supported noble-metal catalysts are considered to be one of the most promising materials achieve complete oxidation volatile organic compounds (VOCs). However, noble metals tend agglomerate under synthesis/reaction conditions and easily poisoned by halogen compounds, resulting in reduced catalytic activity stability. Herein, Pt nanoparticles (∼2 nm) encapsulated ZSM-5 (Pt/Z-En) with a series Si/Al molar ratios were prepared one-pot synthesis strategy using tetraammineplatinum nitrate as metal precursor, their performance for VOCs was explored. The characterizations showed that Pt–zeolite interaction dispersion significantly enhanced after encapsulation zeolite. In VOC (toluene model reactant) experiment, Pt/Z-En possessed higher compared impregnation method (Pt/Z-Im). addition, hydrophobic modification increasing ratio facilitated adsorption toluene restricted (1,2-dichloroethane) on catalyst, which further promoted Pt/Z-200-En catalyst 200 gave optimum performance, conversion 98% at temperature low 214 °C long-term
