Photocatalytic technology has been considered as an efficient protocol to drive chemical reactions in a sustainable and green way. With the assistance of semiconductor-based materials, heterogeneous photocatalysis converts solar energy directly into that can be readily stored. It employed several fields including CO2 reduction, H2O splitting, organic synthesis. Given near-infrared (NIR) light o...

nanoparticles classified in 4 overall groups containing: metallic nanoparticles, ceramic nanoparticles, polymeric nanoparticles and semiconductor nanoparticles. these nanoparticles are used in some biomedical applications such as carrying medicine and photographing agents. with attention to different criteria which are both qualitative and quantitative, selecting the most suitable nanoparticles...

In this review, we provide an overview of recent progress in nanocarbons with different dimensions as noble-metal-free co-catalysts for photocatalysts. We put emphasis on the interface engineering between nanocarbon co-catalysts and various semiconductor photocatalysts and the novel properties generating of nanocarbon co-catalysts, also including the synthesis and application of nanocarbon-base...

a method for the degradation of pyrrolidine in water is described. the method relaies on the photocatalytic degradation of pyrrolidine to co2 and nh3 by uv irradiation and using titanium dixide semiconductor as a photocatalyst. compared with direct photolysis, the semiconductor catalytic photolysis gave consistently higher degradation yields for pyrrolidine in water. the effects of variable par...

A facile and mild solution method has been discovered for the synthesis of complex PbTe hopper crystals in large quantities, which are highly similar to the cubic halite skeletal crystals formed from extreme supersaturation in salt lakes existing in nature. This route may provide a new approach to growing other complex semiconductor structures of high hierarchy.

An anthracene derivative, 2,6-diphenyl anthracene (DPA), was successfully synthesized with three simple steps and a high yield. The compound was determined to be a durable high performing semiconductor with thin film device mobility over 10 cm(2) V(-1) s(-1). The efficient synthesis and high performance indicates its great potential in organic electronics.

By examining the process of heat transfer at tubular reactor for LD-PE synthesis, it can be concluded that free electrons exists during polymerization. Additionally, no free electrons occur in the absence of polymerization. A model that can explain and describe this behavior of ethylene under high pressure is the semiconductor model.
