Dopant Atoms

The incorporation of dopant atoms alters the structure of MoS2, resulting in unique properties and practical applications. Herein, a facile and low-cost approach for producing N-doped molybdenum disulfide (N-MoS[Formula: see text] was carried out using melamine and MoS2 in a laboratory tube furnace at 400[Formula: see text]C for 2[Formula: see text]h. The N-MoS2 fluorescent probe showed sensitive response to Hg[Formula: see text] in a wide concentration range of 0.4–10[Formula: see text][Formula: see text]M with a low limit of 28[Formula: see text]nM. The practical applicability of detecting Hg[Formula: see text] in lake water samples may open a new way to evaluate Hg[Formula: see text] in wastewater.
