Hydrogen production from biomass via<\/em> hydrothermal gasification using <\/strong>Ni-Ce catalysts supported on Kaolin<\/strong><\/p>\n

Recently, PhD student Mr. Zhi-qiang Wang supervised by Prof. Zhen Fang<\/strong>, collaborated with Dr. Sonil Nanda (Dalhousie University) and Prof. Janusz A Kozinski (Lakehead University) published a research article in International Journal of Hydrogen Energy about Hydrogen production from biomass via<\/em> hydrothermal gasification using Ni-Ce catalysts supported on Kaolin.<\/p>\n

The development of efficient and stable catalysts for the effective gasification of biomass waste is crucial for advancing renewable hydrogen production. In this study, a Ni\u2013Ce bimetallic catalyst supported on calcined kaolin (Ni\u2013Ce\/c-Kaolin) was prepared via co-impregnation and applied to the supercritical water gasification of cotton stalks at 340\u2013400\u202f\u00b0C and 16\u201330\u202fMPa. Under the optimized conditions (380\u202f\u00b0C, 5\u202fmin, 0.5\u202fg cotton stalks, and 0.5\u202fg catalyst), the H2<\/sub> yield increased from 1.85 to 21.82\u202fmmol\/g, and the specific surface area rose from 4.74 to 26.46\u202fm\u00b2\/g; the introduction of 2.5\u202fwt% Ce further enhanced catalytic activity, achieving an H2<\/sub> yield 2.25 times higher than that of Ni\/c-Kaolin. The addition of Ce altered the reduction behavior and electronic structure of Ni; XPS analysis indicated that the Ce3+<\/sup>\/Ce4+<\/sup> redox cycle promoted oxygen mobility, while TGA and FT-IR results revealed that Ce suppressed carbon deposition and facilitated the participation of surface hydroxyl groups in the reaction. Gasification experiments with different crop residues showed that cotton stalks exhibited the highest gasification efficiency (70.06%) and H2<\/sub> yield (21.82\u202fmmol\/g), surpassing those of rice and wheat straw. Ni\u2013Ce\/c-Kaolin catalyst retained high catalytic activity and structural stability after undergoing recycling tests. This work reveals a new route for the high-value utilization of agricultural residues, while also confirming the potential of kaolin as an alternative to conventional alumina supports.<\/p>\n
