Area of Science:

• Catalysis
• Plasma Science
• Materials Science

Background:

• Plasma-assisted dry reforming of methane (DRM) offers low-temperature syngas production.
• Designing catalysts for dynamic plasma environments is challenging.

Purpose of the Study:

• To develop a catalyst optimized for plasma-catalytic DRM.
• To investigate the performance and stability of the engineered catalyst.

Main Methods:

• Synthesis of a Ni@graphitic carbon catalyst with tailored pore-surface architecture.
• Evaluation of catalytic performance under ambient conditions with low power input.
• Long-term stability testing over 100 hours.
• Combined theoretical and experimental analysis of catalytic mechanisms.

Main Results:

• Achieved high CO and H2 production rates (442.56 and 294.4 mmol h−1 g−1).
• Demonstrated stable performance and structural integrity over 100 hours.
• Exhibited superior energy efficiency and productivity.

Conclusions:

• The engineered Ni@graphitic carbon catalyst is highly effective for plasma-DRM.
• Unique mesoporous architecture and Ni-C/O hetero-coordination enhance performance.
• This approach offers a pathway for efficient, low-energy, carbon-neutral C1 conversion.
