Synthesis and Characterization of a Distinct Zinc Stannate‐Copper Metal‐Organic Framework (ZnSnO3@H3BTC‐Cu MOF): Unveiling Outstanding Photocatalytic and Antibacterial Properties

Abstract In the present era, a significant amount of research work is focused on eco‐friendly technologies and advanced liquid waste management strategies. Notably, industries primarily textile chemical processing sectors which are inherently involved with a wide array of dye usage, are integral focal points for these transformative endeavors. Against this backdrop, we have successfully synthesized an innovative photocatalyst with a remarkable capability to rapidly neutralize deleterious dyes within an astonishingly brief span of 4–6 minutes, facilitated by exposure to UV‐visible irradiation. Briefly, our approach entails the hydrothermal synthesis of a composite material based on zinc stannate (ZnSnO3) nanoparticles integrated with the copper‐decorated metal‐organic framework (ZnSnO3@H3BTC‐Cu MOF). The resulting material is endowed with a crystalline and porous architecture that confers a specific surface area measuring 437.25 m2 g −1 , a value surpassing that of unadorned nano‐ZnSnO3 by a factor of approximately 15 (29.11 m2 g −1 ). Noteworthy beyond its enhanced surface features, the newly synthesized ZnSnO3@H3BTC−Cu MOF exhibits remarkable antibacterial efficacy against gram‐positive S. aureus and gram‐negative E. coli bacterial strains. It might also be considered a stable photocatalyst to be used in wastewater treatment, as evidenced by the photoelectrochemical and photocatalytic investigation.
