Combined Methane Cracking for H2 Production with CO2 Utilization for Catalyst Regeneration Using Dual Functional Nanostructured Particles

Yu-Chun Zeng,
Zhi Xuan Law,
De-Hao Tsai

Abstract: A two-stage chemical looping approach is demonstrated for sustainable hydrogen production through methane decomposition (CH 4 → C + 2H 2 ) combined with cyclic catalyst regeneration via the reverse Boudouard reaction (C + CO 2 → 2CO). A Nibased spherical nanoparticle cluster, fabricated using a continuous aerosol-based synthetic approach, is developed for effective cyclic catalysis of the above two chemical reactions. A sufficiently high CO 2 conversion rate for catalyst regeneration (in terms of TOF CO 2 , 36… Show more
