Abstract

Hierarchical LaFeO3 fibers were prepared by a sol-gel nanocasting method using a cotton cloth as the template. The resulting LaFeO3 fibers inherited the initial network morphology of the template very well and showed enhanced catalytic CO oxidation activity and satisfactory stability compared to the counterpart particles prepared by the conventional sol-gel method.

摘要

采用溶胶-凝胶纳米铸造法以棉布为模板制备了分级 LaFeO3 纤维。所得 LaFeO3 纤维很好地继承了模板的初始网络形态，与传统溶胶-凝胶法制备的对应颗粒相比，表现出增强的 CO 氧化催化活性和令人满意的稳定性。
