Using the same reaction condition at 2.25 MPa, 483 K, and the gas feed volume of CO2 to H2 ratio of 1:3, remarkable difference in terms of CO2 conversion and methanol selectivity were obtained using these two different supports. Copper and zinc oxide loaded onto alumina and silicon carbide, denoted as CZA and CZS respectively were characterized using Brunauer-Emmet-Teller (BET) and their result showed that CZA and CZS BET surface area were lower compared to their respective unloaded support because of the pore blockage. The morphologies of catalysts were also characterized using field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM). The experimental data showed that CZA exhibit lower CO2 conversion of 10.77 but producing higher methanol selectivity of 77.09 compared to that of CZS. These results may due to the difference of textural properties, morphologies and chemical nature of the supports involved. © 2016 Author(s). date: 2016 publisher: American Institute of Physics Inc. official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85006026322&doi=10.1063%2f1.4968073&partnerID=40&md5=168f31d42ebbeb16179c156f06419c7d id_number: 10.1063/1.4968073 full_text_status: none publication: AIP Conference Proceedings volume: 1787 refereed: TRUE isbn: 9780735414518 issn: 0094243X citation: Halim, N.S.A. and Zabidi, N.A.M. and Tasfy, S.F.H. and Shaharun, M.S.
