Quantum Dot Based Heterostructures for Unassisted Photoelectrochemical Hydrogen Generation
Rodenas, Pau; Song, Taeseup; Sudhagar, P.; Marzari, Gabriela; Han, Hyungkyu; Badia Bou, Laura; Gimenez, Sixto; Fabregat-Santiago, Francisco; Mora-Sero, Ivan; Bisquert, Juan; Paik, Ungyu; Kang, Yong Soo Wiley (2013-02)TiO2 hollow nanowires (HNWs) and nanoparticles (NPs) constitute promising architectures for QDs sensitized photoanodes for H2 generation. We sensitize these structures with CdS/CdSe quantum dots by two different methods ... -
Three dimensional-TiO2 nanotube array photoanode architectures assembled on a thin hollow nanofibrous backbone and their performance in quantum dot-sensitized solar cells
Han, Hyungkyu; Sudhagar, P.; Song, Taeseup; Jeon, Yeryung; Mora-Sero, Ivan; Fabregat-Santiago, Francisco; Bisquert, Juan; Kang, Yong Soo; Paik, Ungyu Royal Society of Chemistry (2013-02-18)Facile synthesis of TiO2 nanotube branched (length [similar]0.5 μm) thin hollow-nanofibers is reported. The hierarchical three dimensional photoanodes (H-TiO2-NFs) (only [similar]1 μm thick) demonstrate their excellent ...
