Boosting turquoise hydrogen and carbon nanotube production <i>via</i> catalytic methane decomposition: influence of active metal ratios in Fe5-Co-Zn/γ-Al₂O₃ nanocatalysts.

ABSTRACT: The present study reports the synthesis of a series of nanocatalysts (NCs) comprising iron (Fe), cobalt (Co), and zinc (Zn) supported on γ-Al₂O₃ nanopowder (Fe5-Co-Zn/γ-Al₂O₃) by tuning the metals stoichiometric ratio using a facile co-precipitation approach. The powder X-ray diffraction patterns and Raman spectra revealed that the freshly synthesized Fe5-Co-Zn/γ-Al₂O₃ is composed of hexagonal Fe₂O₃, cubic Co₃O₄, and hexagonal ZnO phases. The NCs exhibited efficient performance in CH₄ decomposition, yielding turquoise hydrogen (H₂) and carbon nanotubes (CNTs) as solid carbon by-products. The active metals consisted of 50% Fe, 5% Co, and 15% Zn as Fe5Co0.5Zn1.5
