The electrochemical study of single‐layer, 2D MoS 2 nanosheets reveals a reduction peak in the cyclic voltammetry in NaCl aqueous solution. The electrochemically reduced MoS 2 (rMoS 2 ) shows good conductivity and fast electron transfer rate in the [Fe(CN) 6 ] 3‐/4− and [Ru(NH 3 ) 6 ] 2+/3+ redox systems. The obtained rMoS 2 can be used for glucose detection. In addition, it can selectively detect dopamine in the presence of ascorbic acid and uric acid. This novel material, rMoS 2 , is believed to be a good electrode material for electrochemical sensing applications.
