Resumen
IN THIS RESEARCH PAPER, THE CO OXIDATION PERFORMANCE OF MESOPOROUS CEO2 NANOLEAVES WAS COMPARED WITH COMMERCIAL CEO2 BULK POWDER. THE MESOPOROUS CEO2 NANO LEAVES WERE OBTAINED BY THE SOLVOTHERMAL METHOD. THE STRUCTURE AND MORPHOLOGY OF THE SYNTHESIZED CEO2 NANO LEAVES OUTCOMES WERE CHARACTERIZED BY DIFFERENT TECHNIQUES. THE OBTAINED RESULTS FROM X-DIFFRACTION (XRD) ANALYSIS AND HIGH-RESOLUTION TRANSMISSION ELECTRON MICROSCOPY (HR-TEM) WERE SUGGESTED THAT THE CUBIC STRUCTURE OF CEO2 DISPLAYED NANO LEAVES ALONG WITH LINE DISPLACEMENTS WHICH FAVOR MORE ELECTRON ACTIVE SITES. FURTHERMORE, THE X-RAY PHOTOELECTRON SPECTROSCOPY (XPS) RESULTS REVEALED THAT THE PREPARED NANO LEAVES EXPOSED CE3+, CE4+ AND O STATES. THE EXISTED LINE DISPLACEMENTS AND OXYGEN VACANCY ARE BENEFICIAL FOR CO OXIDATION. COMPARED TO COMMERCIAL BULK CEO2, SYNTHESIZED CEO2 NANO LEAVES SHOWED SUPERIOR CO OXIDATION PERFORMANCE.
