Catalytic methane pyrolysis over supported catalytic systems: Coupling turquoise hydrogen production with value-added carbon (nano)structures formation

Poster Abstract: In the context of the green energy transition, hydrogen (H2) technologies are expected to play a major role in decarbonizing the energy sector. Turquoise H2 offers a promising alternative to conventional fossil-based H2 production and renewable dependent green H2 routes [1]. Catalytic methane (CH4) cracking presents a single-step approach for methane decomposition into H2 and solid carbon without direct CO2 emissions or the need for complex carbon capture infrastructure. However, significant challenges remain, particularly regarding catalytic stability and resistance to deactivation [2]. This doctoral research aims to establish a proof-of-concept framework for the design and evaluation of novel supported catalysts for efficient CH4 pyrolysis by systematically investigating metal-support interactions, active site architecture, and catalyst durability. In parallel, the study will examine the formation and growth of nanostructured carbon co-products. A combination of characterization techniques, including gas sorption analysis, X-ray diffraction, temperature-programmed reduction, and scanning and transmission electron microscopy, will be applied before and after reaction to elucidate structure-performance relationships [3]. Ultimately, this work targets a dual-value technological pathway for CH4 pyrolysis by developing robust catalysts capable of sustaining CH4 conversion and H2 production, while directing carbon growth towards high-value nanostructures, such as carbon nanotubes or nanofibers, for advanced materials applications.
