Biodiesel production for transportation The cover picture shows the use of a mesoscopic assembled zirconia nanoarchitecture as an effective catalyst in the biodiesel reaction. In their Full Paper on p. 3050 ff., S. A. El-Safty and S. K. Das report a simple fabrication of mesoscopic zirconia nanocatalysts. Owing to the open framework, large surface area, and the presence of ample acidic sites, the catalysts showed excellent catalytic activity in the biodiesel reaction for conversion of long-chain fatty acids to their methyl esters. The maximum biodiesel yield was ≈100%, even after multiple reuse cycles.
