- W4210576365 abstract "Background: In recent times, development of an efficient electrode material for the determination of caffeine content in beverages and other related sources becomes essential. In this work, for the first time, a novel electrochemical sensor based on carbonized Cu-4,4’-bipyridine-trimesic interlinked metal-organic framework (CBT-MOF) was prepared, characterized by various surface analytical techniques and employed for the effective sensing of caffeine. Method: Copper-4,4’-bipyridine-trimesic acid interlinked MOF (CBT-MOF) was prepared by simple solvo-thermal method and it was carbonized at different temperatures. Significant findings The superiority of CBT-500 may be associated with rise in the Conductivity of the copper oxide nanoparticles by increasing the carbonizing temperature at 500 °C. which enhances the electron transfer kinetics between the analyte and the copper oxide nanoparticle. Increase in temperature above 500 °C, (CBT-600 and CBT-700), results in lower conductivity, thereby decreasing the electron transfer kinetics between the electrode/electrolyte interface. As expected, the amperometric detection of caffeine on fabricated electrode material provided a linear dynamic range from 1 to 10 μM with a low detection limit and higher sensitivity of 0.0190 μM and 0.0848 mA μM−1 cm−2. Further, the fabricated electrode material remained stable, leading to a promising sensor material for the analysis of caffeine in coffee samples." @default.
