Journal ArticleDOI
Quantum dot sensitized solar cells based on an optimized combination of ZnS, CdS and CdSe with CoS and CuS counter electrodes
TL;DR: In this article, the first quantum dot layer consisted of 75% CdS and 25% ZnS and it was followed by a CdSe layer and by an additional ZnSe layer on the top.
Journal ArticleDOI
Preparation of ZnO nanoparticles by thermal decomposition of zinc alginate
Sotirios Baskoutas,Panayotis Giabouranis,Spyros N. Yannopoulos,Vassilios Dracopoulos,Lajos Tóth,Athanassios Chrissanthopoulos,Nikolaos Bouropoulos +6 more
TL;DR: In this article, a new method to produce zinc oxide nanocrystals is presented, based on the thermal decomposition of zinc alginate gels, which are produced in the form of beads by ionic gelation between a zinc solution and sodium alginates.
Journal ArticleDOI
Synthesis and characterization of ZnO/NiO p–n heterojunctions: ZnO nanorods grown on NiO thin film by thermal evaporation
Athanassios Chrissanthopoulos,Sotirios Baskoutas,Nikolaos Bouropoulos,Nikolaos Bouropoulos,Vassilios Dracopoulos,Panagiotis Poulopoulos,Spyros N. Yannopoulos +6 more
TL;DR: In this paper, the structure and morphology of the as-grown film of ZnO nanorods were characterized by scanning electron microscopy, and X-ray diffraction revealing a rather well ordered array of NNODs aligned normally to the substrate.
Journal ArticleDOI
Visible-light photocatalytic hydrogen production from ethanol–water mixtures using a Pt–CdS–TiO2 photocatalyst
TL;DR: In this article, a photoelectrochemical cell with short-circuited anode and cathode was used to photocatalytically treat water-ethanol mixtures and produce hydrogen under visible-light irradiation.
Journal ArticleDOI
Novel ZnO nanostructures grown on carbon nanotubes by thermal evaporation
Athanassios Chrissanthopoulos,Sotirios Baskoutas,Nikolaos Bouropoulos,Vassilios Dracopoulos,Dimitrios Tasis,Spyros N. Yannopoulos +5 more
TL;DR: In this paper, the formation of ZnO/carbon nanotubes heterostructures achieved by means of a thermal evaporation method was reported, and the main building block of the observed morphologies was the nanorod whose self-assembling resulted in various structures such as polypods and nano-hedgehogs.
