The comments above underline that further studies will be needed to ascertain the origin of the selectivity differences observed by Tsang and co-workers. In particular, operando techniques need to be used, since Grunwaldt et al.showed that Cu wetted differently ZnO depending on the experimental conditions. It would be interesting to assess 1) possible changes in shape and size of the copper particles under reaction conditions, 2) the possibility of Zn¨CCu surface alloys formation, and 3) the Cu surface area in situ after reaction (by N2O reactive frontal chromatography in the case of Cu¨CZnO platelets and Cu¨CZnO rods. |
