experiment example 1

[0023] Experimental example 1: 1.0g cadmium chloride (CdCl 2 ) was dissolved in 30mL of water, 1.5g of layered titanate (Na-Ti-O) line pipe was added, ion exchange was carried out at 100°C for 15h, cooled to room temperature, filtered, and washed with water to obtain the ionic Cd 2+ layered titanate wire tubing. Take 1.5g of the exchanged pipe material and put it into the reaction solution, add 30mL of water, and react at 160°C for 10h to prepare Cd 2+ ion-doped TiO 2 wire tubing.

experiment example 2

[0024] Experimental example 2: 1.0g manganese chloride (MnCl 2 ) was dissolved in 30mL of water, 1.5g of layered titanate wire pipe (Na-Ti-O) was added, and ion exchange was carried out at 100°C for 15h, cooled to room temperature, filtered, and washed with water to obtain Mn-containing 2+ Ionic layered titanate wire tubing. Take 1.5g of the exchanged pipe material and put it into the reaction solution, add 30mL of water, and carry out the reaction at 160°C for 10h to obtain Mn 2+ ion-doped TiO 2 wire tubing.

experiment example 3

[0025] Experimental example 3: 1.0g manganese acetate (Mn(Ac) 2 ) was dissolved in 30mL of water, 1.5g of layered titanate wire pipe (Na-Ti-O) was added, and ion exchange was carried out at 100°C for 15h, cooled to room temperature, filtered, and washed with water to obtain the ionic Cd 2+ layered titanate wire tubing. Take 1.5g of the exchanged pipe material and put it into the reaction solution, add 30mL of water, and carry out the reaction at 160°C for 10h to obtain Mn 2+ ion-doped TiO 2 wire tubing.
