Pt/Ce-TiO₂ Catalyst

Superior activity and stability

A Ce-modified TiO2 support creates a dual metal-support interaction that simultaneously enhances low-temperature activity and long-term stability for methane combustion, overcoming the typical activity-stability trade-off in Pt-based catalysts.

{'zh': '275', 'en': '275'} °C

Advantages

Enhanced low-temperature activity

Electronic metal-support interaction promotes high-valent Pt species for efficient methane activation at relatively low temperatures.

Suppressed sintering

Covalent metal-support interaction with robust Pt-O-Ce bonds suppresses sintering and reduction, enhancing long-term stability.

Balanced activity and stability

This dual regulation balances reactivity and stability, overcoming the activity-stability trade-off in Pt-based catalysts.

Applications

• Catalytic methane combustion：Enable complete methane oxidation at lower temperatures for lean methane abatement.
• Environmental catalysis：Remove low-concentration methane to cut greenhouse gas emissions.
