[0050] The invention provides a method for preparing iron-tin oxide nanomaterials, comprising the following steps:
[0051] A) Mix soluble iron source, soluble tin source, xonotlite nanowires and water to form a reaction solution, and then perform hydrothermal reaction to obtain iron-tin oxide nanoparticles.
[0052] The specific conditions and steps of the hydrothermal reaction are not particularly limited in the present invention, and the specific conditions and steps of the hydrothermal reaction well known to those skilled in the art can be used, and those skilled in the art can select according to actual production conditions, raw material conditions and product requirements. For selection and adjustment, the temperature of the hydrothermal reaction of the present invention is preferably 100-200°C, more preferably 120-180°C, most preferably 140-160°C; the time of the hydrothermal reaction of the present invention is preferably 0.5- 24h, more preferably 1-20h, more preferab...
