          Abstract

          Ultrathin-nanosheet-based 3D hierarchical In 2S 3 with enhanced photocatalytic and photoelectrochemical performance was synthesized via an organic component depletion method with inorganic–organic hybrids as precursors.

          Abstract

          Engineering two-dimensional (2D) ultrathin nanosheets into a hierarchical porous structure is one of the important challenges in material chemistry. We report a chemical transformation route to inorganic hierarchical In 2S 3 with a 3D microsphere-like porous structure stacked by 2D ultrathin nanosheets via an organic-component depletion method of inorganic–organic hybrids as precursors. The as-prepared In 2S 3 has enhanced photocatalytic property for the degradation of methyl orange as well as a stable photoelectrochemical property.

          Metal dichalcogenide nanosheets: preparation, properties and applications.

          Two-dimensional (2D) nanomaterials have received much attention in recent years, because of their unusual properties associated with their ultra-thin thickness and 2D morphology. Besides graphene which has aroused tremendous research interest, other types of 2D nanomaterials such as metal dichalcogenides have also been studied and applied in various applications including electronics, optoelectronics, energy storage devices, and so on. In this tutorial review, we will take MoS(2) as a typical example to introduce the latest research development of 2D inorganic nanomaterials with emphasis on their preparation methods, properties and applications.

            Spatial separation of photogenerated electrons and holes among {010} and {110} crystal facets of BiVO4.

            Charge separation is crucial for increasing the activity of semiconductor-based photocatalysts, especially in water splitting reactions. Here we show, using monoclinic bismuth vanadate crystal as a model photocatalyst, that efficient charge separation can be achieved on different crystal facets, as evidenced by the reduction reaction with photogenerated electrons and oxidation reaction with photogenerated holes, which take place separately on the {010} and {110} facets under photo-irradiation. Based on this finding, the reduction and oxidation cocatalysts are selectively deposited on the {010} and {110} facets respectively, resulting in much higher activity in both photocatalytic and photoelectrocatalytic water oxidation reactions, compared with the photocatalyst with randomly distributed cocatalysts. These results show that the photogenrated electrons and holes can be separated between the different facets of semiconductor crystals. This finding may be useful in semiconductor physics and chemistry to construct highly efficient solar energy conversion systems.

              Synthesis of few-layer MoS2 nanosheet-coated TiO2 nanobelt heterostructures for enhanced photocatalytic activities.

              MoS(2) nanosheet-coated TiO(2) nanobelt heterostructures--referred to as TiO(2)@MoS(2)--with a 3D hierarchical configuration are prepared via a hydrothermal reaction. The TiO(2) nanobelts used as a synthetic template inhibit the growth of MoS(2) crystals along the c-axis, resulting in a few-layer MoS(2) nanosheet coating on the TiO(2) nanobelts. The as-prepared TiO(2)@MoS(2) heterostructure shows a high photocatalytic hydrogen production even without the Pt co-catalyst. Importantly, the TiO(2)@MoS(2) heterostructure with 50 wt% of MoS(2) exhibits the highest hydrogen production rate of 1.6 mmol h(-1) g(-1). Moreover, such a heterostructure possesses a strong adsorption ability towards organic dyes and shows high performance in photocatalytic degradation of the dye molecules.
