The present invention relates to a method for preparing self assembled growth silicon nano-tube by hydrothermal method. In the method, water is used as solvent, and non-toxic silicon oxide is added to the water, then mixture of the water and the silicon oxide is fed into a sealed reaction kettle while stirring, the mixture is kept at a certain temperature and a certain pressure for a period of time; the weight of the said silicon oxide is not more than 10% of weight of the solvent, and a magnetic stirrer is used for stirring. The present invention completely utilizes non-toxic raw materials, and the materials and preparation process do not pollute the environment, so the method satisfies the development trend of modern industry. La présente invention concerne un procédé destiné à la préparation par voie hydrothermique d'un nanotube de silicium autoassemblé. Ce procédé consiste : à utiliser de l'eau comme solvant ; à ajouter de l'oxyde de silicium non toxique à l'eau ; à introduire le mélange composé d'eau et
