Hierarchical porous Ti ₂ Nb ₁₀ O ₂₉ nanospheres prepared by a facile solvothermal method are demonstrated with superior Li-ion storage performance with high capacities and good cycling life.

Integrated VG/MoO ₂ core/shell arrays prepared by a powerful plasma enhanced chemical vapor deposition–electrodeposition method are demonstrated to have superior sodium ion storage performance, high capacities and good cycling life.

A new photocatalyst, alveolate Cu _2−x Se microsheets, is developed, which reveals superior photocatalytic discoloration of Rhodamine B.

The extremely chemically sensitive magnetic behavior changing from paramagnetism to ferromagnetism induced by incorporation of La (2.5%) in SrCo ₂ As ₂ is shown.

A series of β-FeSe nanorods composited g-C ₃ N ₄ were prepared. The structure, morphology, chemical state, photocatalytic activity, electrochemical impedance and photoluminescence of β-FeSe/g-C ₃ N ₄ composites were well characterized. It is found that the decolourization rate of 3 wt% β-FeSe/g-C ₃ N ₄ composites reaches 4.4 times than that of g-C ₃ N ₄ . The improved photocatalytic properties could be ascribed to the reduced recombination of photogenerated electrons and holes, which is derived from the excellent ability of β-FeSe to capture and transfer electrons. This work provides an alternative co-catalyst for decolourizing organic matter.
