Journal ArticleDOI
Photocatalytic Decomposition of H2O2 on Different TiO2 Surfaces Along with the Concurrent Generation of HO2 Radicals Monitored Using Cavity Ring Down Spectroscopy
TL;DR: In this paper, the decomposition of H2O2 on illuminated TiO2 films was investigated using cavity ring down spectroscopy (CRDS), where a mixture of H 2O2 and O2 gas was flowed through a cavity reactor which contained a TiO 2-coated plate.
Journal ArticleDOI
Highly durable photoelectrochemical H2O2 production via dual photoanode and cathode processes under solar simulating and external bias-free conditions
TL;DR: In this paper, a photoelectrochemical (PEC) cell that maximizes the utilization of solar energy by having double side generation of H2O2 on both the photoanode and cathode was demonstrated.
Journal ArticleDOI
Production of Molecular Iodine and Tri-iodide in the Frozen Solution of Iodide: Implication for Polar Atmosphere.
Kitae Kim,Kitae Kim,Akihiro Yabushita,Masanori Okumura,Alfonso Saiz-Lopez,Carlos A. Cuevas,Christopher S. Blaszczak-Boxe,Dae Wi Min,Ho Il Yoon,Wonyong Choi +9 more
TL;DR: It is proposed that an accelerated abiotic transformation of iodide to gaseous I2 in ice media provides a previously unrecognized formation pathway of active iodine species in the polar atmosphere.
Journal ArticleDOI
How g-C3N4 Works and Is Different from TiO2 as an Environmental Photocatalyst: Mechanistic View.
Jonghun Lim,Hyejin Kim,Jihee Park,Gun-hee Moon,Junie Jhon M. Vequizo,Akira Yamakata,Jinwoo Lee,Wonyong Choi +7 more
TL;DR: The negative effect of Pt on CN is ascribed to that Pt catalytically decomposes in-situ generated H2O2 (a main precursor of OH radical), which hinders ●OH generation in the two photocatalytic systems.
Journal ArticleDOI
Holey Pt Nanosheets on NiFe-Hydroxide Laminates: Synergistically Enhanced Electrocatalytic 2D Interface toward Hydrogen Evolution Reaction.
Sun Woo Jang,Soumen Dutta,Amit Kumar,Yu-Rim Hong,Hanuel Kang,Shinbi Lee,Sunmin Ryu,Wonyong Choi,In Su Lee +8 more
TL;DR: This work offers a gateway to produce active metal nanosheets tailored with a suitable active-template surface in order to invent and enforce futuristic catalysis technologies.
