Embodiment 1

[0033] 1 g of nano-MoS 2The powder was dispersed in 100 mL of n-butyllithium cyclohexane solvent, and heated at 80° C. for 2 days in an Ar atmosphere protection condition. Then cleaned by distilled water and sonicated for 1 h, the exfoliated nano single-layer or few-layer MoS 2 nanomaterials. Subsequently, 100 mg of exfoliated MoS 2 Disperse in methanol solvent, add 200mg C 12 h 8 B 2 o 4 , heated at 80 °C for 8 h in an Ar atmosphere protection condition, and then washed the obtained product with ethanol to obtain double B atom-modified MoS 2 Material.

[0034] Boron-doped MoS obtained by 2 The modification was carried out on the glassy carbon electrode for electrocatalytic water splitting reaction test, and the results showed that the electrocatalytic effect was better than that of unmodified MoS 2 better electrocatalytic performance. Electrochemical performance test results show that boron-doped MoS 2 The electrochemical water-splitting activity was significantly ...
