The two hitherto unknown lithium holmium(III) ortho-thiophosphates(V) Li9Ho2[PS4]5 and Li15Ho7[PS4]12 crystallize in the monoclinic space group C2/c with lattice parameters a=1489.43(9) pm, b=979.84(6) c=2051.68(12) ?=96.221(3)° for (Z=4) a=2826.73(16) b=1003.25(6) c=3361.46(19) ?=113.992(3)° (Z=5). While extends Li9RE2[PS4]5 series, can be regarded as a cation-distribution variant of Li6RE3[PS...

Oxide materials with a perovskite-derived layered structure often show better photocatalytic performance compared to nonlayered of similar composition. Here we investigate the catalytic activity for oxygen evolution reaction (OER) on surfaces Carpy–Galy oxides Sr2Ta2O7 and Sr2Nb2O7. We find that (010) surface parallel layering shear plane is not relevant photocatalysis. The (100) perpendicular ...

We report on the superconductivity in ternary transition metal tellurides Ta2Pd3Te5 and Nb2Pd3Te5, which have a one-dimensional crystal structure. Single-crystalline polycrystalline samples of show nonmetallic electron conduction, while Ti or W doping results metallic behavior with bulk superconducting at 2–4 K. In contrast, are found to be isostructural Ta2Pd3Te5, 3.3 The structure physical pr...
