Journal of the American Ceramic Society, Volume 109, Issue 3, March 2026.. ABSTRACT Water and air pollution are pervasive issues, impacting the majority of global citizens. In response, geopolymers functionalized with photocatalytic metal oxides have emerged as sustainable materials for environmental remediation. This study examines how the Si/Al molar ratio (1 and 2) and photocatalytic WO3 loading (WO3/Al molar ratios of ...
