The MoS2 nanosheets were synthesized by a facile hydrothermal reaction. At first, the Ti foil ((0.5 mm., Sinopharm Chemical Reagent Co., Ltd.)) was treated by acetone and deionized water under ultraphonic conditions. Then, the MoS2 nanosheets were grown on the substrate. A 30 mL mixed water solution containing NaMoO4∙2H2O (120 mg)(A.R., Sinopharm Chemical Reagent Co., Ltd.) and CH4N2S (190 mg) (A.R., Sinopharm Chemical Reagent Co., Ltd.) was used as the reactant to prepare the MoS2 in an oven at 200 °C for 20 h [12 (link)]. After that, the obtained sample was taken out and rinsed with water and ethanol repeatedly before drying in air at 60 °C.

The electrochemical experiment was carried out based on the CHI660 electrochemical analyzer of Shanghai Chenhua Instrument Co., Ltd. A three-electrode system was used, in which a 3 mm GCE was used as the working electrode and a platinum wire was used as the counter electrode. The saturated calomel electrode is the auxiliary electrode. Sigma HD scanning electron microscope (SEM) was used to observe the morphology of the modified electrodes. The polytetrafluoroethylene liner reactor, electronic analytical balance, suction filter device, ultrasonic cleaning machine, electric heating blast drying oven, and high-speed centrifuge are all from Shanghai Chenhua Instrument Co., Ltd.
The drugs used in the experiment were Na2MoO4·2H2O, CH4N2S, C2H5OH, FeCl3·6H2O, FeCl2·4H2O, NH3·H2O, CH3COOH, Nafion (5 wt%) solution, C2H3NaO2, Cd2+ standard solution and other reagents, all purchased from Sinopharm Chemical Reagent Co., Ltd. The purity used was either analytical reagent (AR) or guaranteed reagent (GR). The experimental water was ultrapure water with a resistivity of 18.0 MΩ cm. The actual water samples were taken from the seawater of the Maowei Sea in Qinzhou.

Initially, 2 mmol (NH4)6Mo7O24 (99.95%, Sinopharm Chemical Reagent Co., Ltd., Shanghai, China) and 10 mmol CH4N2S (99.95%, Sinopharm Chemical Reagent Co., Ltd., Shanghai, China) were introduced into 80 mL of deionized water, followed by stirring at a speed of 600 r min−1 for a duration of 2 h until complete dissolution was achieved. The solution was then transferred to a 100 mL PTFE-lined autoclave. Subsequently, the CNFs prepared above were added to the solution. The PTFE-lined autoclave was reacted at 200 °C for 24 h with a heating rate of 2 °C min−1. After completion of the reaction, the sample was thoroughly washed and dried overnight at 60 °C in a vacuum oven with a heating rate of 1 °C min−1. Finally, the hybrid composite materials were calcined at 350 °C for 2 h with a heating rate of 2 °C min−1 under a nitrogen atmosphere to yield the desired MoS2/CNFs composite (depicted in Figure 1 b). The synthesis process for pure MoS2 nanomaterials is comparable to the preparation method for MoS2/CNFs, except that pure carbon fibers are not employed as the matrix material during the synthesis process.

To prepare CuS CEs, a 50 mL solution including Na2S2O3·5H2O (1 M) and CuS·5H2O (1 M, Tianjin Guangfu Science and Technology Seven Development Co., Ltd.) was prepared and the pH was adjusted to 2.0 by acetic acid (Aladdin). Clean FTO substrates were put in the solution and kept at 70 °C for 3 h. Then, the substrates were dried at 130 °C for 30 min to acquire CuS CEs. As for the preparation of the CuS/brass-mesh CE, the copper mesh (Hebei Xingheng Materialtech Co., Ltd., China) was soaked in 70 °C hydrochloric acid (36%, Sinopharm Chemical Reagent Co., Ltd.) for 2 h to remove the zinc on the surface. Then, the copper mesh was washed with deionized water and dried at room temperature. The treated Cu mesh was soaked in a mixed solution of CH4N2S (0.01 M, Sinopharm Chemical Reagent Co., Ltd.) and C2H8N2 (Ethylenediamine, 1.5 M, Tianjin Guangfu Science and Technology Seven Development Co., Ltd.) for 24 h, and then the previous cleaning and drying steps were repeated.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
