Example Embodiment
[0021] Embodiment 1. This embodiment provides a photocatalyst for the production of hydrogen from water, which is characterized by comprising the following raw materials: nano-titanium dioxide and cobalt or nickel salt as the active component, graphene as the carrier, and copper as the auxiliary agent Source or zinc source compound.
Example Embodiment
[0022] Example 2. This example provides a method for photolysis of water to produce a hydrogen catalyst. Firstly, 14.3 g (0.1 mol) of cuprous oxide is weighed and added to 50 ml of ethanolamine, and ultrasonicated for 10 minutes until the mixture is uniform. Weigh 4 g (0.05 mol) of nano titanium dioxide particles with an average particle size of 50 nm, add them to the suspension of ethanolamine and copper dichloride, and then keep the temperature at 30° C. and perform ultrasound for about 20 minutes until the mixture is uniformly mixed. Then weigh 32g of graphene and add it to the above ethanolamine mixture system, raise the temperature to 50°C and continue to sonicate, 0.2 hours later, put the graphene mixture into a mortar or beaker and heat it. Glass can be used during heating. Stir with a rod or a magnetic stirrer to make the heating process more uniform. Heat at 90°C for 2 hours to obtain a solid solution. Then the solid solution was dried under a nitrogen atmosphere at 60...
Example Embodiment
[0023] Embodiment 3, this embodiment provides a method for photolysis of water to produce hydrogen catalyst. Firstly, 14.3 g (0.1 mol) of cuprous chloride is weighed and added to 400 ml of diethanolamine, and ultrasonicated for 8 minutes until the mixture is uniform. Weigh 24 g (0.3 mol) of nano titanium dioxide particles with an average particle diameter of 100 nm, add them to the suspension of diethanolamine and cuprous chloride, and then keep the temperature at 50° C. and perform ultrasound for about 20 minutes until the mixture is uniformly mixed. Then weigh 600g of graphene and add it to the above-mentioned diethanolamine mixture system, raise the temperature to 80°C and continue sonication. After 0.5 hours, put the graphene mixture into a mortar or beaker and heat it. It can be used during heating. Stir with a glass rod or a magnetic stirrer to make the heating process more uniform. Heat at 200°C for 4 hours to obtain a solid solution. Then the solid solution was dried un...
