A new three-dimensional (3-D) inorganic metal–oxygen network vanadoborate Na3H10[Ni(H2O)2(VO)6(B10O22)2]·NH4·19H2O (1) constructed from lantern-type {(VO)6(B10O22)2} clusters, NaO6 polyhedra and NiO6 octahedra, was successfully synthesized by a hydrothermal method. In the structure, the {V6B20} clusters are linked together through NiO6 octahedral bridges, resulting in 1-D chains along the c-axis. The 1-D chains are further connected by NaO6 polyhedra to give rise to a 3-D open-framework structure. Furthermore, lots of NH4+ and H2O molecules are accommodated in the void of the structure, and may interact with the [V6B20] system via N–H⋯O, O–H⋯O hydrogen bonds, constructing a complex hydrogen-bonding network system. Strikingly, compound 1 exhibited a high proton conductivity of 3.22 × 10−3 S cm−1 at 50 °C under 100% RH with an activation energy of 1.66 eV. [ABSTRACT FROM AUTHOR]

For the first time, bulk-like g-C3N4 was achieved through initiating layer-by-layer assembly, which involves the important process of artificially manipulating protonated and oxygen doped g-C3N4 nanosheets. When acting as a photocatalyst under UV-visible light irradiation, bulk-like g-C3N4 exhibited an excellent photocatalytic H2 production rate of 1538 μmol h−1 g−1, about 8 times higher than that of the bulk g-C3N4 counterpart.

For the first time, bulk-like g-C 3 N 4 was achieved through initiating layer-by-layer assembly, which involves the important process of artificially manipulating protonated and oxygen doped g-C 3 N 4 nanosheets. When acting as a photocatalyst under UV-visible light irradiation, bulk-like g-C 3 N 4 exhibited an excellent photocatalytic H 2 production rate of 1538 μmol h -1 g -1 , about 8 times higher than that of the bulk g-C 3 N 4 counterpart.
