Abstract
La présente invention concerne du phosphate de fer de type feuille nanométrique, son procédé de préparation et son utilisation. Le procédé de préparation comprend les étapes suivantes consistant à : dissoudre une source de phosphore et une source de fer dans une solution acide, ajouter un oxydant, et les mélanger pour obtenir une solution de phosphate de fer ; ajouter un agent auxiliaire de précipitation dans une partie de la solution de phosphate de fer, le chauffer jusqu'à ébullition, puis le diluer pour réaction afin d'obtenir une suspension de phosphate de fer primaire ; et ajouter goutte à goutte la solution de phosphate de fer restante dans la suspension de phosphate de fer primaire, puis la chauffer pour réaction afin d'obtenir du phosphate de fer. Dans la présente invention, du phosphate de fer primaire est préparé à partir d'une source de phosphore et d'une source de fer en tant que matières premières au moyen d'une réaction de précipitation par dilution, et l'agent auxiliaire de précipitation est ensuite ajouté pour une précipitation en deux étapes pour réguler la croissance du phosphate de fer, de telle sorte que la morphologie du phosphate de fer est contrôlée, l'agent auxiliaire de précipitation ajouté pouvant non seulement réguler la morphologie, mais peut également être utilisé en tant que dopant, améliorant ainsi la surface spécifique et la densité de compactage du phosphate de fer.
