摘      要：We present a new method to prepare TiO_(2) sea−urchin-like structures,which involves the initial formation of tubular nanostructures and subsequent self-assembly of the nanotubes into micrometer-scale sea-urchin-like *** also investigate the important role of alkali aqueous conditions in the preparation of TiO_(2) sea−urchin-like *** facile and cost-effective approach provides a new route for the preparation of self-assembled TiO_(2) *** addition,the performance of the as−synthesized TiO2 sea-urchin-like structures as the active layer of an efficient solar energy harvester is also studied and discussed.
