Abstract

We have prepared new TiO 2 paste and carbon counter electrodes for the large area and low cost DSSC manufacturing applications. The carbon counter electrodes were prepared from commercial carbon paste in different sintering temperatures. The photovoltaic properties of the DSSCs made of TiO 2 paste based photoanode and carbon counter electrodes showed that the sintering temperature of counter electrode strongly influences the power conversion efficiency. The carbon counter electrode sintered at 400 °C showed the conversion efficiency of 3.53% which was found comparable to the standard platinum counter electrode based DSSC efficiency of 3.96%.

22. pn-Junction Rectifiers Based on p-ZnO and n-ZnO Nanoparticles

Abstract

We form pn-junctions by electrostatic binding of a p-type and an n-type ZnO nanoparticle. Current−voltage characteristics of pn-junctions are rectifying in nature. Individual components of the junction do not show any rectification. An np-junction, formed by reversing the binding sequence of the two types of nanoparticles, shows rectification in the reverse bias direction. By controlling the type of dopants in the ZnO nanoparticles, pn+ (and n+p) and nn+ (and n+n) junctions are formed that exhibit rectification. Current rectification in a junction between two nanoparticles shows that a depletion layer may have formed even in the quantum dot regime.

24. In situ photo-assisted deposition of MoS₂ electrocatalyst onto zinc cadmium sulphide nanoparticle surfaces to construct an efficient photocatalyst for hydrogen generation

Abstract

We reported herein a facile and scalable preparation process for MoS(2)-decorated Zn(x)Cd(1-x)S hybrid photocatalysts for hydrogen generation. Zn(x)Cd(1-x)S nanopowder was first prepared from commercially available precursors employing a solution based process. MoS(2) hydrogen evolution reaction catalyst was then loaded onto the Zn(x)Cd(1-x)S nanopowder via a photo-assisted deposition process which employed mild conditions (room temperature, atmospheric pressure and visible light illumination). Thus, this process represents an important advantage in the large scale production of semiconductor/MoS(2) hybrid photocatalysts in comparison to the conventional method relying on thermal decomposition of (NH(4))(2)[MoS(4)] precursor at high temperature and under H(2)S pressure. The best Zn(0.2)Cd(0.8)S/MoS(2) 3% showed two hundred-and-ten times (210 times) faster hydrogen generation rate on visible light illumination compared with that obtained for un-treated Zn(0.2)Cd(0.8)S. That was the most impressive catalytic enhancement ever recorded for a semiconductor photocatalyst decorated with a noble metal free electrocatalyst.

25. Coordination-Polymeric Nanofibers and their Field-Emission Properties

Author

Abstract

The large-scale fabrication of nanofibers of coordination polymers (CPs) is reported for the first time from CP gel precursors by the electrospinning method. In the absence of organic polymeric additives, viscous solutions suitable for drawing fibers have been made by diluting the gel precursors, which are obtained by mixing Ni(OAc)(2) and 4-trifluoromethylbenzoic acid with 4,4'-bis(pyridyl)ethylene (bpe) or 4,4'-bipyridine (bpy) linear spacer ligands in organic solvents. One-dimensional polymeric structures have been proposed for these gels and nanofibers based on the crystal structures of the compounds isolated. These fibers show some interesting field-emission properties. The results described here may well be extended to other one-dimensional polymers, thus opening the door for processing of the coordination polymers.

Abstract

Bismuth ammonium citrate complex (C24H20Bi4O28 x 6NH3 x 10H2O) interacted with sodium sulphide (Na2S) in presence of beta-cyclodextrin (beta-CD) yielding Bi2S3 nanospheres. Solvothermal treatment of the bismuth complex and dimethyl sulphoxide (DMSO) produced Bi2S3 nanorods. Reaction conditions were optimized to investigate the morphology evolution of the product. Electrical properties of the nanorods were monitored in details.
