Highly ordered mesoporous Cr2O3 materials with enhanced performance for gas sensors and lithium ion batteries

Highly ordered mesoporous Cr2O3 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 Cr2O3 mesoporous replicas from SBA-15 and KIT-6 templates exhibit enhanced performance for gas sensors and lithium ion batteries, compared to the bulk Cr2O3 counterpart.
