Abstract：

Porous　Sr0.25H1.5Ta2O6·　H2O　(HST)　nanosphere　with　high　surface　area　has　been　prepared　by　a　PVP-assisted　hydrothermal　method　for　the　first　time.　In　the　synthesis,　PVP　played　an　important　role　in　formation　of　porous　nanosphere.　This　approach　could　also　be　used　to　prepare　other　nanostructured　tantalate　efficiently　without　rigorous　reaction　conditions.　The　photocatalytic　activities　were　evaluated　by　the　decomposition　of　benzene　in　gaseous　phase.　Results　showed　that　benzene　could　be　effectively　degraded　and　mineralized　over　the　HST　samples.　Due　to　the　unique　porous　structure,　larger　surface　area,　and　stronger　oxidizing　ability　of　the　photogenerated　holes,　HST　nanosphere　exhibited　a　superior　photocatalytic　activity　for　the　degradation　of　benzene　compared　with　HST　nanopolydera　and　TiO2　(Degussa　P25).　The　effect　of　the　crystallinity　of　the　samples　on　the　photocatalytic　activities　was　also　discussed.　©　2013　Elsevier　B.V.
