Hydrogen production through solar-driven water splitting is a promising approach and an alternative to the conventional steam reforming of natural gas coal gasification. The growing energy demand environmental degradation carbon-emitting fossil fuels urge transition in usage non-renewable renewable sources energy. photocathodes photoelectrochemical (PEC) water-splitting cell are essential for d...

The emerging two-dimensional (2D) materials exhibit a wide range of electronic properties, ranging from insulating hexagonal boron nitride (hBN), semiconducting transition metal dichalcogenides (TMDCs) such as molybdenum disulfide (MoS2) and tungsten diselenide (WSe2), to semi-metallic graphene. The plethora of 2D materials together with their heterostructures, which are free of the traditional...

Synthesis of low-cost, eco-friendly, semiconducting solar-energy materials with excellent photocatalytic activity [high surface area, good reactant adsorption, photon harnessing in the visible region, and low charge recombination] for application in...

The trapping of electrons by grain boundaries in semiconducting and insulating materials is important for a wide range of physical problems, for example, relating to: electroceramic materials with applications as sensors, varistors and fuel cells, reliability issues for solar cell and semiconductor technologies and electromagnetic seismic phenomena in the Earth's crust. Surprisingly, considerin...

Ferroelectrics have been attracting increasing attention as good candidates for multifunctional materials because of their fascinating properties. However, their large bandgap has been a roadblock limiting their application in optoelectronics and photovoltaics, among other applications. Hybrid ferroelectrics have the potential to combine the advantages of both molecular materials and ferroelect...

−75− Synthesiology English edition Vol.6 No.2 pp.75-83 (Sep. 2013) Then, in 1993, “single-wall CNTs” were discovered. In CNT research, the theoretical calculations were done actively due to their relatively simple molecular structure. From the calculations, it was predicted that, despite being a substance consisting solely of carbon atoms, CNTs would have extremely excellent properties such as ...

The rational assembly of monomers, in principle, enables the design of a specific periodicity of polymeric frameworks, leading to a tailored set of electronic structure properties in these solid-state materials. The further development of these emerging systems requires a combination of both experimental and theoretical studies. Here, we investigated the electronic structures of two-dimensional...
