P25 loaded few layered molybdenum disulfide (MoS2) nanosheets (P25@MoS2) are successfully synthesized through a facile one-step hydrothermal process. The bi-catalytic activities, i.e., photocatalytic and electrocatalytic activities, of the as-prepared nanomaterials have been investigated. For the as-prepared products, the photocatalytic performances were investigated by degrading simulated pollutant under sunlight irradiation, and the hydrogen evolution reaction evaluated the electrocatalytic performances. The results indicate that P25@MoS2 possesses excellent activities in both photocatalysis and electrocatalysis. The presence of MoS2 broadens the light absorption range of P25 and improves the separation and transformation efficiency of photogenerated carriers, thus improving its photocatalytic performance. The existence of P25 inhibits the aggregation of MoS2 to form more dispersed MoS2 nanosheets with only few layers increasing its active sites. Thereby, the electrocatalytic performance is heightened. The excellent multifunction makes the as-prepared P25@MoS2 a promising material in the fields of environment and energy.

In the course of a systematic field study, anisotropic alkali and alkaline earth vanadates have been accessed through a straightforward, one-step hydrothermal process. They are formed quantitatively from V2O5 and alkali- or alkaline earth halide solutions after a few days of autoclave treatment in the temperature range between 100 and 220 °C. The presence of ionic additives leads to an interplay between the formation of isotropic crystalline phases and the production of fibrous oxide materials, such as a novel magnesium vanadate. The influence of the hydrothermal parameters and of the alkali/alkaline earth halides on the emerging phases and morphologies has been investigated in the course of a systematic study. The results are compared with other vanadate- and transition metal oxide-based hydrothermal systems, and the emerging trends are discussed with respect to the development of predictive synthetic concepts for nanostructured vanadium oxides.

FePO4·2H2O with orthorhombic flower-like microstructure was synthesized by a facile hydrothermal process which was of low-cost and easy processing in large area. The formation mechanism of the flower-like FePO4·2H2O was discussed in details by investigating the different concentration of reactants and reaction time. The results show that the morphology of FePO4·2H2O changed from microsphere to flower-like structure, which possess an unique morphology with six petals and the angle of each petal being 60o. The formation mechanism of FePO4·2H2O flowers can be explained by the dissolution-recrystallization and crystal splitting.

Monodispersed MoS2ultrathin nanosheets have been successfully fabricated by a facile hydrothermal process assisted by ionic liquid Brij56. The effect of Brij56 on the morphology and structure of MoS2has been obviously observed. XRD shows that the as-prepared MoS2assisted by Brij56 has the weak and broad peak of (002) planes, which implies the small size and well dispersed structure of MoS2nanosheets. TEM and SEM images reveal that MoS2ultrathin nanosheets have small size and few stacking layers with the adding of Brij56. HRTEM images prove that MoS2appears to have a highly monodispersed morphology and to be monolayer ultrathin nanosheets with the length about 5–8 nm, which can provide more exposed rims and edges as active sites for hydrogen evolution reaction. Brij56 has played a crucial role in preparing monodispersed MoS2ultrathin nanosheets as excellent electrocatalysts. The growth mechanism of monodispersed MoS2has been discussed in detail.
