The crystalline structure, and morphology were characterized by X-ray diffraction analysis and SEM images. Ni (II) and Ce (III) were incorporated into cryptomelane, substituted for Mn (III) and Mn (IV) resulting an increase of Mn-average-oxidation-state from 3.6 to 3.8 for un-doped and co-doped samples, respectively. With different amount of precursor-cerium concentration, NiCe1.0 improved the ethanol conversion by a factor of 8 compared to unmodified K-OMS-2. Additionally, NiCe1.0 showed a significant increase of ethanol conversion with reaction temperature. Over above 90% of ethanol was total oxidized at 150 C suggesting a potential Ni-Ce-OMS-2 catalyst for removing volatile organic compounds at low temperature.</p> </p></abstract><publication_date><month>04</month><day>18</day><year>2023</year></publication_date><pages><first_page>68</first_page><last_page>72</last_page></pages><publisher_item><identifier id_type="pii">gnest_04949</identifier></publisher_item><doi_data><doi>10.30955/gnj.004949</doi><timestamp>1716176693</timestamp><resource>https://journal.gnest.org/publication/gnest_04949</resource></doi_data></journal_article></journal></body></doi_batch> </div>
