<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 H<sub>2</sub>O, SO<sub>2</sub> H<sub>2</sub>S 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>

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

ConspectusMethane complete oxidation is an important reaction that part of the general scheme used for removing pollutants contained in emissions from internal combustion engines and, more generally, processes. It has also recently attracted interest as option removal atmospheric methane context negative emission technologies. Methane, a powerful greenhouse gas, can be converted to carbon dioxide and water via its oxidation. Despite burning being facile because sustains after ignition, strong C–H bonds require catalyst perform at low temperatures absence flame so avoid formation nitrogen oxides, such those produced flares. This process allows obtained under conditions usually lead higher emissions, cold start case engines. Among several options include homo- heterogeneous catalysts, supported palladium-based catalysts are most active systems this reaction. Finely divided palladium activate 150 °C, although conversion not reached until 400–500 °C practical applications. Major goals achieve catalytic possible temperature utilize expensive metal efficiently.Compared any other transition metal, oxides orders magnitude reactive water. During last few decades, much research been devoted unveiling origin high activity their phase, effect support, promoters, defects, with goal further improving reactivity. There overall agreement trends, yet there noticeable differences some details performance palladium, including phase reasons deactivation poisoning. In Account we summarize our work space using well-defined especially model surfaces prepared colloidal nanocrystals precursors, spectroscopic tools unveil about chemistry catalysts.
