Embodiment 1
[0022] Dissolve molybdenum chloride and thiourea in ethanol under stirring, wherein the concentrations of molybdenum chloride and thiourea are 0.33mol / L and 0.66mol / L respectively, and then drop-coat the mixed solution onto the surface of graphite paper treated with hydrophilization (The surface of graphite paper contains a large amount of -OH, -COOH, -NH 2 ), dried and annealed in Ar at 800°C for 60 min. After the sample is cooled naturally, the molybdenum disulfide / graphite paper electrode can be obtained.
Embodiment 2
[0024] Dissolve molybdenum chloride and thiourea in ethanol under stirring, wherein the concentrations of molybdenum chloride and thiourea are 0.33mol / L and 0.99mol / L respectively, and then drop-coat the mixed solution onto the hydrophilized graphite paper Surface (the surface of graphite paper contains a large amount of -OH, -COOH, -NH 2 ), dried and annealed in Ar at 800°C for 60 min. After the sample is cooled naturally, the molybdenum disulfide / graphite paper electrode can be obtained.
[0025] figure 1 The powder XRD of the sample prepared in this embodiment is shown. By working with standard PDF cards (MoS 2 PDF#37-1492) comparison shows that the prepared sample is molybdenum disulfide. It shows that after annealing in Ar at 800°C, molybdenum chloride and thiourea react to form molybdenum disulfide.
[0026] figure 2 SEM image of the sample prepared for this implementation example. The brick shape in the figure is MoS 2 , the bottom is graphite paper, it can be ...
Embodiment 3
[0032] Dissolve molybdenum chloride and thiourea in ethanol under stirring, wherein the concentrations of molybdenum chloride and thiourea are both 0.33mol / L and 1.32mol / L respectively, and then drop-coat the mixed solution onto the hydrophilized graphite paper Surface, dried and annealed in Ar at 800°C for 60min. After the sample is cooled naturally, the molybdenum disulfide / graphite paper electrode can be obtained.
