Example Embodiment
[0026] Example 1:
[0027] α-Layered zirconium phosphate material preparation method: 0.294 g (7.0 mmol) sodium fluoride (NaF, Aladdin Reagent (Shanghai) Co., Ltd.), 22.5 g (68.4 mmol) zirconium oxychloride octahydrate (ZrOCl) 2 • 8H 2 O, Sinopharm Chemical Reagent Co., Ltd.) and 24.95 mL of distilled water were respectively added to a 150 mL PTFE-lined reactor, stirred thoroughly to completely dissolve the solid reactants, and then added 15.81 g (161.3 mmol) phosphoric acid (H 3 PO 4 , Aladdin Reagent (Shanghai) Co., Ltd.), stir evenly, put the reactor into 180 o The reaction was carried out in oven C for 36 hours. After the reaction, the solid product was filtered and washed with distilled water until it was neutral, and the α-ZrP sample was obtained after natural air drying in the air.
[0028] α-ZrP and MoS 2 The preparation method of the mixed powder: 8.0 g α-ZrP and 4.0 g molybdenum disulfide (MoS 2 , Aladdin Reagent (Shanghai) Co., Ltd.) was mixed in an agate tank, and 12.0 g ...
