ABSTRACT The coupling of photocatalysis and piezocatalysis has gained significant interest among researchers. In this study, we present the photo‐piezocatalytic activity exhibited by bismuth titanate (Bi 4 Ti 3 O 12 ) glass‐ceramics (BTO‐GC). BTO‐GC samples were prepared in a glass system 40Bi 2 ‐40B ‐20TiO (in mol %) using melt‐quench technique. catalyst was characterized X‐ray diffraction (XRD) technique Raman spectroscopy for its structure phase analysis. Surface morphology chemical composition analyzed scanning electron microscopy (SEM) photoelectron (XPS), respectively. catalytic performance evaluated photocatalysis, piezocatalysis, photo‐piezocatalysis processes. Methylene blue (MB) dye degradation UV–Vis spectrophotometer. A maximum ~86% achieved solar light process. This study highlights synergistic advances understanding underlying mechanism.
