Single-crystalline, wormlike hematite photoanodes for efficient solar water splitting
Jae Young Kim,Ganesan Magesh,Duck Hyun Youn,Ji-Wook Jang,Jun Kubota,Kazunari Domen,Jae Sung Lee +6 more
TL;DR: In this article, a hematite photoanode showing a stable, record-breaking performance of 4.32 µmW/cm2 photoelectrochemical water oxidation current at 1.23 µmV vs. RHE under simulated 1-sun irradiation was reported.
Single-crystalline, wormlike hematite photoanodes for efficient solar water
splitting Young Kim,Ganesan Magesh,Duck Hyun Youn,Ji-Wook Jang,Jun Kubota,Kazunari Domen,Jae Sung Lee +6 more
TL;DR: The hematitle has a unique single-crystalline “wormlike” morphology produced by in-situ two-step annealing at 550°C and 800°C of β-FeOOH nanorods grown directly on a transparent conducting oxide glass via an all-solution method.
Journal ArticleDOI
Highly active and stable hydrogen evolution electrocatalysts based on molybdenum compounds on carbon nanotube-graphene hybrid support
Duck Hyun Youn,Suenghoon Han,Jae Young Kim,Jae Yul Kim,Hunmin Park,Sun Hee Choi,Jae Sung Lee +6 more
TL;DR: Among the prepared catalysts, Mo2C/CNT-graphene shows the highest activity for hydrogen evolution reaction with a small onset overpotential and Tafel slope of 58 mV/dec as well as an excellent stability in acid media.
Journal ArticleDOI
Electrode Degradation in Lithium-Ion Batteries.
Joshua P. Pender,Gaurav Jha,Duck Hyun Youn,Joshua M. Ziegler,Ilektra Andoni,Eric J Choi,Adam Heller,Bruce Dunn,Paul S. Weiss,Reginald M. Penner,C. Buddie Mullins +10 more
TL;DR: This Review highlights the developments of electrode materials and characterization tools for rechargeable lithium-ion batteries, with a focus on the structural and electrochemical degradation mechanisms that plague these systems.
Journal ArticleDOI
Highly Conformal Deposition of an Ultrathin FeOOH Layer on a Hematite Nanostructure for Efficient Solar Water Splitting.
TL;DR: An ultrathin (ca. 2 nm) amorphous FeOOH overlayer was deposited conformally on a hematite nanostructure by a simple solution-based precipitation method, to generate an oxygen evolution cocatalyst for efficient solar water splitting.
