Journal ArticleDOI
Branched TiO2 Nanorods for Photoelectrochemical Hydrogen Production
In Sun Cho,Zhebo Chen,Arnold J. Forman,Dong Rip Kim,Pratap M. Rao,Thomas F. Jaramillo,Xiaolin Zheng +6 more
TL;DR: A hierarchically branched TiO(2) nanorod structure that serves as a model architecture for efficient photoelectrochemical devices as it simultaneously offers a large contact area with the electrolyte, excellent light-trapping characteristics, and a highly conductive pathway for charge carrier collection.
Journal ArticleDOI
Simultaneously Efficient Light Absorption and Charge Separation in WO3/BiVO4 Core/Shell Nanowire Photoanode for Photoelectrochemical Water Oxidation
Pratap M. Rao,Lili Cai,Chong Liu,In Sun Cho,Chi Hwan Lee,Jeffrey M. Weisse,Peidong Yang,Peidong Yang,Xiaolin Zheng +8 more
TL;DR: These core/shell nanowires achieve the highest product of light absorption and charge separation efficiencies among BiVO4-based photoanodes to date and, even without an added catalyst, produce a photocurrent of 3.1 mA/cm under simulated sunlight and an incident photon-to-current conversion efficiency of ∼ 60% at 300-450 nm.
Journal ArticleDOI
Boosting the solar water oxidation performance of a BiVO4 photoanode by crystallographic orientation control
Hyun Soo Han,Sun Shin,Dong Hoe Kim,Ik Jae Park,Ju Seong Kim,Po-Shun Huang,Jung-Kun Lee,In Sun Cho,Xiaolin Zheng +8 more
TL;DR: In this article, the authors used a preferentially [001]-oriented BiVO4 (p-BVO) as a photoanode for photoelectrochemical water splitting, achieving an impressive photocurrent density at 1.23 V vs. the reversible hydrogen electrode (RHE).
Journal ArticleDOI
Codoping titanium dioxide nanowires with tungsten and carbon for enhanced photoelectrochemical performance
In Sun Cho,Chi Hwan Lee,Yunzhe Feng,Manca Logar,Pratap M. Rao,Lili Cai,Dong Rip Kim,Robert Sinclair,Xiaolin Zheng +8 more
TL;DR: This is the first experimental demonstration that codoped TiO2:(W, C) nanowires outperform monodopedTiO2:W and TiO1:C and double the saturation photocurrent of undoped Ti O2 for photoelectrochemical water splitting.
Journal ArticleDOI
Reduced Graphene Oxide/Mesoporous TiO2 Nanocomposite Based Perovskite Solar Cells
Gill Sang Han,Gill Sang Han,Young Hyun Song,Young Un Jin,Jin-Wook Lee,Nam-Gyu Park,Bong Kyun Kang,Jung-Kun Lee,In Sun Cho,Dae Ho Yoon,Hyun Suk Jung +10 more
TL;DR: The rGO/mp-TiO2 nanocomposite film with an optimal rGO content shows 18% higher photon conversion efficiency compared with the TiO2 nanoparticles based perovskite solar cells.
