Carbon–neutral hydrogen production by catalytic methane decomposition: a review

Environmental Chemistry Letters, Journal Year: 2024, Volume and Issue: 22(4), P. 1623 - 1663

Published: April 20, 2024

Abstract The global hydrogen demand is projected to increase from 70 million tons in 2019 more than 200 2030. Methane decomposition a promising reaction for H 2 production, coupled with the synthesis of valuable carbon nanomaterials applicable fuel cell technology, transportation fuels, and chemical synthesis. Here, we review catalytic methane decomposition, focus on catalyst development, deactivation, reactivation, regeneration, economics. Catalysts include mono-, bi-, trimetallic compounds carbon-based compounds. Catalyst deactivation induced by coke deposition. Despite remarkable strides research, industrialization remains at an early stage.

Catalytic decomposition of methane: Ni-promoted perovskite oxide catalysts for turquoise hydrogen and carbon nanomaterials Co-production

Energy Materials, Journal Year: 2025, Volume and Issue: 5(3)

Published: Jan. 14, 2025

This study investigates the effectiveness of catalytic decomposition methane for producing turquoise hydrogen and solid carbon nanomaterials. The focus is on developing cost-effective high-performance Nickel (Ni)-promoted perovskite oxide catalysts. A series transition metal, Ni-promoted (La0.75Ca0.25)(Cr0.5Mn0.5)O3-δ (LCCM) catalysts have been successfully prepared using water-based gel-casting technology. These are designed to decompose into nanomaterials, achieving negligible CO2 emissions. X-ray diffraction results indicate that solubility Ni at B-site LCCM limited, x ≤ 0.2. Field Emission Scanning Electron Microscopy analysis xNi-LCCM, calcined 1050 °C ten h in air, confirms severe catalyst sintering with excess nickel distributed around particles. At a 750 operating temperature, molar ratio 1.5 yields maximum output 17.04 gC/gNi. Increasing ratios 2.0 2.5 17.17 gC/gNi 17.63 gC/gNi, respectively, showing minor changes. morphology nanomaterials unaffected by NiO promoter remains nearly same within scope this study.
