Highly ordered mesoporous Cr_2O_3 materials with enhanced performance for gas sensors and lithium ion batteries

摘要

Highly ordered mesoporous Cr_2O_3 materials with high specific surface area and narrow pore size distribution were successfully prepared by a vacuum assisted impregnation method. Both 2-dimensional hexagonal and 3-dimensional cubic Cr_2O_3 mesoporous replicas from SBA-15 and KIT-6 templates exhibit enhanced performance for gas sensors and lithium ion batteries, compared to the bulk Cr_2O_3 counterpart.
