摘要：

Nb2O5　nanorods　were　fabricated　by　acetic　acid　solvothermal　route　combined　with　heat　treatment　of　as-obtained　one　dimensional　(1D)　niobium　oxide　nanowires　at　400°C　for　1h.　XRD,　SEM,　TEM　analyses　indicate　that　Nb2O5　nanorods　prepared　by　calcination　have　hexagonal　phase　and　crystalize　along　[001]　direction.　These　Nb2O5　nanorods　can　be　used　as　catalysis　for　the　degradation　of　methylene　blue　(MB)　and　rhodamine　B　(RhB)　aqueous　solution　under　UV　light　illumination.　Experimental　results　show　that　Nb2O5　nanorods　possess　well　photocatalytic　activity　for　the　degradation　of　both　MB　and　RhB　under　UV　light,　which　is　of　great　interest　in　environmental　purification.　Photocatalytic　efficiency　decreases　with　the　increase　of　dye　concentration,　and　the　removal　effect　of　MB　is　better　than　that　of　RhB　due　to　strong　adsorption　of　MB　onto　Nb2O5　nanorods.
