The complete catalytic oxidation of propane (C3H8) at low temperatures remains challenging due to the competitive adsorption between O2 and C3H8 molecules. In this study, we propose an innovative approach enhance by strategically designing active Ptδ+ sites with modulated electronic structures on F-doped TiO2-supported Pt catalyst (Pt/F-TiO2), which exhibits 50 90% conversion 200 320 °C. Our mechanistic study reveals that electron coupling 5d F 2p alters d orbital property, leads generation abundant efficient electron-enriched species. These new facilitate promote activation chemisorbed into superoxide species, in form bridge Pt-(O–O)ad-Ti, synergistically facilitates methyl C–H cleavage C3H8. This presents strategy for structure engineering Pt-based catalysts, paving way development high-performance catalysts oxidation.

Electric heating is frequently employed to treat volatile organic compounds (VOCs) through catalytic combustion. However, it associated with problems such as slow heating, high energy consumption, and low efficiency. This study explores PdPt/Al2O3 catalysts for igniting methanol (MeOH) H2 combustion, providing internal on-site of catalyst active sites. It also investigates VOCs’ abatement using H2-ignited-MeOH combustion without external heating. Bimetallic enhance activity reduce thermal aging. Hydrogen gas (H2) can initiate the MeOH at room temperature addition very small amounts, even below its explosive limit 4%. process optimizes ignition approximately 350 °C, when concentration 0.01%. method enhances kinetics, converting VOCs into CO2 water. Catalytic performance independent PdPt nanoparticle sizes in fresh spent catalysts, represented XRD STEM. Using hydrogen an agent provides a clean, effective reactions, addressing traditional challenges enhancing decomposition

Glass and crystal are inherently different material states in terms of their structural physical features; consequently, the direct quantitative connection between glass is lacking. Herein, we first show that liquid fragility m, which featured by negative departure degree viscosity with temperature at transition (Tg), has a exponential correlation ratio average longest metal-oxygen phosphorus, silicon, or boron-oxygen bond lengths various oxides including phosphates, silicates, borates. Such result can be rationalized fact m these glass-formers associated total network rigidity determined weakest due to "bucket effect" pair inheritance from crystal. Our work connects features identical composition, providing new viewpoint bridging
