Exploring the Electrocatalytic application of Two-Dimensional Samarium Molybdate (γ-Sm3(MoO4)3) Nanoplatelets for Selective Sensing of Organophosphate Insecticide Oxyparathion

Abstract

Exploration of novel and proficient material through simple, large-scale and green synthesis routes for precise level detection of organophosphate insecticide in real physical systems of soil and water is a predominant concern to the researchers. In this view, we introduced a sensitive and eminently selective electrochemical sensor probe for Oxyparathion (OP) based on sonochemically designed 2D samarium molybdate nanoplatelets (γ-Sm3(MoO4)3; SmM NPs). The sonochemically synthesized SmM NPs catalyst was systematically investigated concerned with the crystal structure, textural morphologies, and physicochemical characteristics by analyzing XRD, Raman, FE-SEM, HR-TEM, and XPS analysis. The fabricated electrode was employed in detection and determination through different voltammetric techniques. The SmM NPs fashioned screen-printed carbon electrode (SmM NPs/SPCE) demonstrated a potentially supreme electrocatalytic activity towards OP detection with lower detection limit, widespread linear amplitude range and good sensitivity of 0.002 µM, 0.01-692 µM, and 0.54 µA µM-1cm-2, correspondingly. Moreover, other interfering materials such as inorganic species, biological compounds and a nitro group containing OPPTs and drugs have no influences for the detection of OP. Besides, SmM NPs/SPCE has also been utilized for OP detection in soil and actual groundwater samples and displayed excellent sensing ability.
