Bismuth oxychloride anchored on waste stainless-steel slag: preliminary assessment of its potential as an active photocatalytic support.

ABSTRACT: Environmental pollution remains a critical barrier to sustainable societal development. In this context, the present work explores a sustainable approach to environmental remediation through the mechanochemical synthesis of bismuth oxychloride (BiOClm) immobilized on waste stainless-steel slags (SSS) at varying proportions. This strategy exemplifies the principles of circular economy by transforming industrial waste into a high-value, photocatalytically functionalized material. The composites were thoroughly characterized in terms of their physicochemical and optical properties, and their photocatalytic activity was evaluated through nitrogen oxide (NOx) abatement under UV and visible light. Although the absolute photocatalytic activity of the composites was lower than that of pure BiOClm,
