Controlled electrodeposition of tungsten oxide nanoparticles on MXene nanosheets-framework for ultrasensitive light enhanced detection of dopamine.

ABSTRACT: In this work, a sensitive and efficient light enhanced electrochemical dopamine sensor based on tungsten oxide nanoparticles electrodeposited on MXene nanosheets modified pencil graphite electrode (MXene-WO_x/PGE) was reported. The prepared substrate was carefully characterized with field emission scanning electron microscopy, energy dispersive X-ray analysis, Raman spectroscopy, electrochemical impedance spectroscopy and voltammetry techniques in details. The surface area of MXene-WO_x/PGE was increased 3.75 times in compare with WO_xNPs/PGE proving the role of MXene as a suitable 2D nanomaterials on the electrode surface. The synergistic effect of 2D MXene and tungsten oxide nanoparticles resulted an improved light current response and admirable photocatalyt
