Abstract
Background
Novel three-dimensional (3D) hydrated ceria-BTC (CeO2–1,3,5-Benzenetricarboxylic-acid) is the important material due to its unique chemical and physical properties compared to the other materials. A novel 3D ceria nanostructure has been examined as a promising and feasible technique for methanol decomposition.
Methods
Novel 3D hydrated ceria-BTC microstructures were successfully synthesized via a hydrothermal route in an aqueous solution. Field emission scanning electron microscope (FE-SEM) and X-ray diffraction (XRD) patterns show that a ceria-BTC framework diameter and length are approximately 1.45–2.4 and 5.5–6.5 µm, respectively, at 130 °C and with pH 2 for 72 h. The hexagonal ceria-BTC microrod comprises organic linkers, which are transformed into hierarchical ceria microrod in the presences of air at 400 °C was confirmed by Fourier transform infrared spectroscopy (FTIR).
Significant Findings
The Ce-O bonding of the hierarchical ceria microrod species has a bond distance and coordination number of 2.44 and 6.89, respectively, which attenuates the Extended X-ray absorption fine structure (EXAFS) spectra. Compared to the ceria powder, the hierarchical ceria microrods produced more oxygen vacancies and Ce3+as shown by the X-ray photoelectron spectroscopy (XPS) and X-ray absorption near-edge structure (XANES) analyses. The ceria microstructure exhibits excellent methanol decomposition activity.
期刊介绍:
Journal of the Taiwan Institute of Chemical Engineers (formerly known as Journal of the Chinese Institute of Chemical Engineers) publishes original works, from fundamental principles to practical applications, in the broad field of chemical engineering with special focus on three aspects: Chemical and Biomolecular Science and Technology, Energy and Environmental Science and Technology, and Materials Science and Technology.
