        In this study, ordered ZnO/CeO2 nanocomposite arrays were synthesized within the monolithic cordierite honeycomb using a simple, green and cost effective hydrothermal method. Primary ZnO seeds with (0 0 2) texture were grown within honeycomb’s channels by dipping technique and subsequent heating of the substrates at 350˚C. The average diameter of ZnO seed particles was estimated to be 60 nm from SEM micrographs by the use of Digimizer software. Highly aligned, compact and homogenous ZnO nanorod arrays with the diameter of 200 nm were formed in monolithic cordierite honeycomb by a novel two-step hydrothermal method at 80 oC. ZnO nanorod arrays were used as a core for the preparation of ceria coating. A ceria coating was deposited on ZnO nanorods in the second step of hydrothermal synthesis. Formation of ZnO and ceria phases was also confirmed by X-ray diffraction results. Manuscript profile
