英文摘要la(oh)(3) nanorods of 15 nm diameter and up to 700 nm long were synthesized using different ph values of the solution used in the hydrothermal synthesis. a more alkaline solution favored the formation of tiny la(oh)(3)nuclei, which grew along the c-axis due to their anisotropic nature and led to the formation of rod-shaped crystals. calcination of the la(oh)(3)nanorods at 773 k gave la2o2co3 nanorods. their basic properties were correlated with their size. as the aspect ratio increased from 2 to 20, the basic sites increased from 0.08 to 0.24 mmol/g, which was due to a higher exposure of (110) planes. in the catalysis of the condensation reaction of benzaldehyde with acetophenone, the reaction rate was correlated with the number of la3(+)-0(2)- pairs on the exposed (110) facets of the la(2)o(2)co(3)nanorods.
