ZnO‐Functionalized Silicon Carbide Ceramic Membranes for Removing Impurities From Biodiesel

International Journal of Ceramic Engineering &Science, Volume 8, Issue 3, May 2026.
Silicon carbide (SiC) ceramic membranes functionalized with zinc oxide (ZnO) were assessed for biodiesel purification through crossflow filtration. The ZnO–SiC membranes effectively retained metallic impurities, especially calcium, sodium, and phosphorus, achieving levels that meet biodiesel quality standards.
