Hierarchical growth of BiOCl on SrO‐Bi2O3‐B2O3 glass ceramics for self‐cleaning applications

Abstract

We grown hierarchical structure of bismuth oxycloride (BiOCl) on SrO‐Bi2O3‐B2O3 (SBBO) transparent glass ceramic. SBBO glass‐ceramics were fabricated via conventional melt‐quenching technique while BiOCl was grown by etching the glass via HCl. Enhanced visible light driven photocatalytic activity and increasing hydrophobic feature were observed on BiOCl grown SBBO than as quenched SBBO glass ceramics. Contact angle analysis showed maximum contact angle of 130.7o on the surface of most BiOCl grown SBBO glass ceramic. Further, under visible light illumination water contact angle decreased from 130.7 o to 30.8o. Such photo induced hydrophilicity and catalytic performance in translucent glass ceramics lead self‐cleaning applications.
