| dc.description.abstract | In this research work, microporous zeolite imidazole frmework-67 (ZIF-67), mesoporous layer double hydroxide (LDH) and core-shell mesoporous bifunctional zeolitic imidazole framework-67@layer double hydroxide (ZIF-67@LDH) structure are prepared. Various characterization techniques such as UV-Visible spectroscopy, XRD, SEM, EDX, and N2 adsorption-desorption analysis are employed to investigate the properties of these materials. The bifunctional catalysts prepared in this study are utilized for the removal of organic pollutants from water and also as non-enzymatic electrochemical biosensors for creatinine detection. The core-shell ZIF-67@LDH material exhibited sustainable bifunctionality, effectively removing organic pollutants through both adsorption and photocatalysis under natural sunlight conditions, achieving an impressive removal efficiency of up to 98% without the need for additional additives. Furthermore, the electrochemical behavior and sensing capabilities of ZIF-67@LDH were evaluated using cyclic voltammetry (CV). The catalyst demonstrated low limit of detection (LOD) and high sensitivity for the detection of creatinine. Its porous nature contributed to excellent selectivity, making it suitable for clinical applications.In summary, ZIF-67@LDH proved to be a highly sensitive, stable, cost-effective, and easily fabricated bifunctional catalyst. Its remarkable performance in water remediation and creatinine sensing highlights its potential for practical applications. This interdisciplinary and multidisciplinary research work integrates various fields such as organic chemistry, inorganic chemistry, electrochemistry and analytical chemistry. The aim of this study is to propose and analyze strategies for the removal of organic pollutants from wastewater, addressing the significant social impact and aligning with the “Sustainable Development Goal” (SDG) 6 of UNO “Clean water and sanitation” by contributing to scientific advancements in this field | |
