TiO Nanotubes Decorated with MoC for Enhanced Photoelectrochemical Water-Splitting Properties.

The presence of Ti in the structure of TiO nanotube arrays (NTs) has been shown to enhance the photoelectrochemical (PEC) water-splitting performance of these NTs, leading to improved results compared to pristine anatase TiO NTs. To further improve the properties related to PEC performance, we successfully produced TiO NTs using a two-step electrochemical anodization technique, followed by annealing at a temperature of 450 °C. Subsequently, MoC was decorated onto the NTs by dip coating them with precursors at varying concentrations and times.

Vertical MoS on SiO/Si and graphene: effect of surface morphology on photoelectrochemical properties.

Two-dimensional materials have attracted intensive attention recently due to their unique optical and electronic properties and their promising applications in water splitting and solar cells. As a representative layer-structured of transition metal dichalcogenides, MoS has attracted considerable devotion owing to its exceptional photo and electro properties. Here, we show that the chemical vapour deposition (CVD) growth of MoS on Si photocathode and graphene/Si photocathode can be used to prepare photoelectrocatalysts for water splitting.

A DFT analyses for molecular structure, electronic state and spectroscopic property of a dithiolene tungsten carbonyl complex.

Bis(dithiolene) tungsten carbonyl complex, W(S2C2Ph2)2(CO)2 was successfully synthesized and the structure, frontier molecular orbital and optical properties of the complex were investigated theoretically using density functional theory calculations. The investigation started with a molecular structure construction, followed by an optimization of the structural geometry using generalized-gradient approximation (GGA) in a double numeric plus polarization (DNP) basis set at three different functional calculation approaches. Vibrational frequency analysis was used to confirm the optimized geometry of two possible conformations of [W(S2C2Ph2)2(CO)2], which showed distorted octahedral geometry.

Synthesis, structure and theoretical investigation into a homoleptic tris(dithiolene) tungsten.

A new homoleptic dithiolene tungsten complex, tris-{1,2-bis(3,5-dimethoxyphenyl)-1,2-ethylenodithiolene-S,S'}tungsten, was successfully synthesized via a reaction of the thiophosphate ester and sodium tungstate. The thiophosphate ester was prepared from 3,5-dimethoxybenzaldehyde via benzoin condensation to produce the intermediate 1,2-bis-(3,5-dimethoxyphenyl)-2-hydroxy-ethanone compound, followed by a reaction of the intermediate with phosphorus pentasulfide. FTIR, UV-Vis spectroscopy, 1H NMR and 13C NMR and elemental analysis confirmed the product as tris{1,2-bis-(3,5-dimethoxyphenyl)-1,2-ethylenodithiolene-S,S'}tungsten with the molecular formula of C54H54O12S6W.
