Efficient Conversion of Seawater Vapor to Hydrogen Using Cu–Fe/Al2O3 Catalysts Assisted by Non-thermal Plasma
This study demonstrates an innovative approach for green and efficient hydrogen production from seawater, utilizing Cu–Fe/Al2O3 catalysts coupled with a dielectric barrier discharge (DBD) system. The catalytic performance was systematically evaluated under varying voltages and Cu/Fe ratios in a DBD reactor to optimize hydrogen production efficiency. Subsequent investigations focused on humidity and gas flow rate effects using the optimal catalyst (Cu/Fe/Al2O3 = 2:1:9). Multimodal characterization (XRD, XPS, FTIR, OES) combined with DFT calculations revealed the mechanistic role of Cu–Fe/Al2O3 in plasma-driven hydrogen generation. The synergistic interaction between Fe and Cu enhanced hydroxyl/hydrogen radical generation through improved adsorption, thereby boosting hydrogen evolution efficiency and yield. The optimized system achieved a maximum hydrogen yield of 7.4 g/kWh at 3 kV operating voltage, 3 L/min argon flow, and 100% relative humidity, establishing an energy-efficient pathway for sustainable hydrogen production from seawater.
期刊介绍:
Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis.
The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
