The invention provides a method for preparing flowerlike nanometer cobalt by using electro-conductive glass FTO, an anodised aluminum template (AAO) and an aqueous high-molecular adhesive as a combined electrode. The method comprises the following steps: (1) preparation of a working electrode: a step of coating the electro-conductive glass with a solution of the aqueous high-molecular adhesive--polyvinyl alcohol (PVA) through spin coating and bonding the anodised aluminum template so as to obtain the FTO/PVA/AAO combined electrode; (2) preparation of an electrolyte: separately preparing cobaltous sulfate and a boric acid solution and mixing the cobaltous sulfate with the boric acid solution; (3) electrodeposition reaction: a step of carrying out constant-voltage electrodeposition on the combined working electrode; and (4) post-treatment: a step of soaking the working electrode having undergone electrodeposition in sodium hydroxide to remove the anodised aluminum template. According to the invention, FTO/PVA/AAO is used as the combined working electrode and constant-voltage electrodeposition is carried out so as to prepare the novel flowerlike nanostructured cobalt; and the method is simple and fast and has the advantages of mild reaction conditions, short time, high efficiency and no need for high temperature and high pressure conditions compared with conventional methods.
