Ingenious design and development of recyclable 2D BiOCl nanotiles attached tri-functional robust strips for high performance selective electrochemical sensing, SERS and heterogenous dip catalysis

This research investigation demonstrates the SPCE catalytic strip in action not only for electrochemistry but also for SERS and catalysis. The fabricated low-cost catalytic strips holds huge potential in realizing industrial demands via eco-friendly manner. In this present work, we have synthesized 2D BiOCl nanotiles (BOC-NT) through hydrothermal procedure and subsequently, we have characterized in detail to understand the crystal architecture, morphology and surface area. Electron microscopy studies reveals a homogeneous 2D morphology without any agglomerations. Through a novel GOD process the SPCE catalytic strips are fabricated. More over this work establishes the first paradigm of SPCE catalytic strips hired for the electrochemical sensing, SERS and the chemicatalysis of Methyl Viologen (MyV), a hazardous herbicide. Upon all the three catalytic investigations, BOC-NT based SPCE catalytic strips performed exceptionally well. In the electrochemical sensing, the strip achieved a remarkable linear range (0.01-1331.1 mu M) with detection limit of 0.0073 mu M. In addition, the plasmonic SERS strip presented an impressive enhancement factor (EF) of 10(6) for MyV coupled with the detection limit of 10(-10 )M. Finally, in the chemicatalysis process our catalytic strip aided in degradation of MyV in 9 min. Further, the possible mechanism for SERS and catalysis is also proposed.
