Abstract

original image

Coke? No thank you! The cover picture shows the use of cobalt nanoparticles supported on graphitized activated carbon in acetone steam reforming (ASR). In their Communication on p. 1299 ff., D. Mei, Y. Wang et al. describe their catalyst's high selectivity to H2 (>80 %), low selectivity to methane (<5 %), and its strong resistance to coke formation. Conversion to acetone is approximately 98 % and remains almost constant (<2 % decrease) over 70 h time-on-stream. This observation is supported further by a theoretical analysis of the ASR reaction mechanism.
