In this study, double-promoted Cu/ZnO catalysts were prepared on Al2O3 and CNTs supports via impregnation method. The physicochemical properties of the catalysts were characterized by XPS, TEM, N2 adsorption, H2-TPR and CO2-TPD analyses. Introduction of Nb and Zr promoters into the Cu-based catalysts on CNTs support resulted in smaller Cu nanoparticles and improved reducibility compared to those of the Al2O3-supported catalyst. The catalyst activity was evaluated in a fixed-bed stainless steel reactor operated at 22.5 bar and 523K. Conversion of CO2 higher than 20 was achieved and product distribution was influenced by the type of catalyst supports. {\^A}{\copyright} 2019 Trans Tech Publications, Switzerland}, keywords = {Alumina; Aluminum oxide; Carbon dioxide; Catalyst activity; Catalysts; Copper; Copper compounds; Fueling; Fuels; Hydrogenation; Physicochemical properties; Zinc compounds, Catalytic hydrogenation; CO2 hydrogenation; Copper-based catalysts; Cu nano-particles; Cu-based catalyst; Impregnation methods; Product distributions; Synthesis and characterizations, Catalyst supports}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85062697912&doi=10.4028\%2fwww.scientific.net\%2fDDF.391.60&partnerID=40&md5=8a16bcdf1ce9f5a08a383b9b404a296f}, issn = {10120386}, author = {Tuan Sulong, T.
