Ag-rGO Nanocomposite as an Efficient Electrochemical Sensor for Thiourea

The nanofabrication of composites-based sensor can be routinely seen in the research literature, but high price restricts its use on a wider scale developing world for establishing sustainable society. Iraj Jodan Synthesized Ag-nanoparticles and alizarin yellow polymer based electrochemical thiourea detection. Alizarin provide stability, chemical attachment electrode surface it is toxic to lungs, mucous membranes, cause organs damage by continuously disclosure it. 1 For solving this problem, r-GO has pasted that provided excellent conduction as well large area had sensitivity low detection limit toward TU. Herein, theme materialized (TU). Briefly, reduced graphene (r-GO) sheets with silver (Ag) nanoparticles impregnated were prepared via hydrothermal reduction method. synthesized nano-composite material was characterized various physiochemical techniques like FTIR, XRD, SEM Cyclic Voltammetry (CV) applied sensing TU, well-known carcinogen. Ag-rGO changed enhanced approximately three times greater anodic current compared rGO five compare GCE. Electrically catalytically oxidation TU achieved GCE, GO, at 0.2 V 0.25 applying cyclic voltammetry (CV). concentrations used 10 μ M 50 M, while anode increased concentration increased. also planned concentrations. increasing scan rate 20, 40, 60, 80 100 mV s −1 . So could recognition real time sample good sensitivity, stability reproducibility.
