Embodiment 1
[0023] A method for preparing a black phosphorus titanium dioxide heterogeneous structure loaded noble metal nano particle material, specifically comprising the following steps:
[0024] (1) Preparation of Heterogeneous Structure Materials of Black Phosphorous Titanium Dioxide
[0025] ① Preparation of black phosphorus: Add 2g of red phosphorus and 15mL of ultrapure water into a 25mL hydrothermal kettle at room temperature, and steam at 200°C for 12 hours to remove the oxide layer on the surface of red phosphorus. Then take it out and dry it, grind it with an agate mortar for 0.5-1h, and then perform mechanical ball milling on the multi-layer black phosphorus precursor under normal temperature and pressure with argon protection, ball milling for 24-48h, and keep the rotation speed at 500r / min. Black phosphorus is obtained after mechanical ball milling.
[0026] ② Preparation of titanium dioxide: Use a pipette to measure 10 mL of tetra-n-butyl titanate and add it to a dry 50 m...
