Abstract：

Porous　nanocrystalline　Ln2Ti2O7　(Ln　=　Nd,　Gd,　Er)　was　prepared　by　a　facile　self-propagating　combustion　method　using　metal　nitrates　(Ln(NO3)3　(Ln　=　Nd,　Gd,　Er),　TiO(NO　3)2)　and　glycine.　The　photocatalytic　activity　of　Ln　2Ti2O7　(Ln　=　Nd,　Gd,　Er)　was　evaluated　by　the　photocatalytic　degradation　of　methyl　orange　(MO).　The　results　showed　that　the　photocatalytic　activity　of　Ln2Ti2O7　(Ln　=　Gd,　Er)　with　cubic　pyrochlore　structure　was　higher　than　that　of　Nd　2Ti2O7　with　monoclinic　perovskite　structure　and　Gd2Ti2O7　showed　the　best　photocatalytic　activity.　The　different　photocatalytic　activities　observed　for　Ln　2Ti2O7　(Ln　=　Nd,　Gd,　Er)　could　be　related　to　its　different　crystal　structures　and　Ln　4f　shells.　©　2014　Published　by　Elsevier　B.V.
