Hierarchical growth of BiOCl on SrO-Bi2O3-B2O3 glass-ceramics for self-cleaning applications
We have 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 130.7 degrees on the surface of most BiOCl grown SBBO glass-ceramic. Furthermore, under visible light illumination water contact angle decreased from 130.7 degrees to 30.8 degrees. Such photo-induced hydrophilicity and catalytic performance in translucent glass-ceramics lead self-cleaning applications.
