Large-Scale Synthesis of Carbon-Shell-Coated FeP Nanoparticles for Robust Hydrogen Evolution Reaction Electrocatalyst
Dong Young Chung,Samuel Woojoo Jun,Gabin Yoon,Hyun-Joong Kim,Ji Mun Yoo,Kug-Seung Lee,Taehyun Kim,Heejong Shin,Arun Kumar Sinha,Soon Gu Kwon,Kisuk Kang,Taeghwan Hyeon,Yung-Eun Sung +12 more
TL;DR: Extended X-ray absorption fine structure analysis combined with electrochemical test shows that carbon shell coating prevents FeP nanoparticles from oxidation, making them highly stable under hydrogen evolution reaction operation conditions.
Journal ArticleDOI
Reversible and cooperative photoactivation of single-atom Cu/TiO2 photocatalysts
Byounghoon Lee,Sunghak Park,Minho Kim,Arun Kumar Sinha,Seong Chan Lee,Euiyeon Jung,Woo Je Chang,Kug-Seung Lee,Jeong Hyun Kim,Sung-Pyo Cho,Hyungjun Kim,Ki Tae Nam,Taeghwan Hyeon +12 more
TL;DR: The atomic-level design and synthetic strategy provide a platform that facilitates valence control of co-catalyst copper atoms, reversible modulation of the macroscopic optoelectronic properties of TiO2 and enhancement of photocatalytic hydrogen generation activity, extending the boundaries of conventional heterogeneous catalysts.
Journal ArticleDOI
Multifunctional Au-ZnO Plasmonic Nanostructures for Enhanced UV Photodetector and Room Temperature NO Sensing Devices
TL;DR: The sensing response of Au-ZnO nancomposite is enhanced both in UV and visible region, as compared to control ZnO, and the sensitivity is observed to be higher in the visible region due to the LSPR effect of Au NPs.
Journal ArticleDOI
Evolution of Hierarchical Hexagonal Stacked Plates of CuS from Liquid−Liquid Interface and its Photocatalytic Application for Oxidative Degradation of Different Dyes under Indoor Lighting
Mrinmoyee Basu,Arun Kumar Sinha,Mukul Pradhan,Sougata Sarkar,Yuichi Negishi,Govind,Tarasankar Pal +6 more
TL;DR: It has been characterized that the solid mass is an assembly of hexagonal copper sulfide (CuS) nanoplates representing a hierarchical structure and an ethanolic dispersion of CuS presents a high band gap energy which assists visible light photocatalytic mineralization of different dye molecules.
Journal ArticleDOI
Direct Synthesis of Intermetallic Platinum–Alloy Nanoparticles Highly Loaded on Carbon Supports for Efficient Electrocatalysis
Tae Yong Yoo,Ji Mun Yoo,Arun Kumar Sinha,Megalamane S. Bootharaju,Euiyeon Jung,Hyeon Seok Lee,Byoung-Hoon Lee,Jiheon Kim,Wytse Hooch Antink,Yong Min Kim,Jongmin Lee,Eungjun Lee,Eungjun Lee,Dong Wook Lee,Dong Wook Lee,Sung-Pyo Cho,Sung Jong Yoo,Sung Jong Yoo,Sung Jong Yoo,Yung-Eun Sung,Taeghwan Hyeon +20 more
TL;DR: A novel synthetic strategy to directly produce highly dispersed MPt alloy nanoparticles (M = Fe, Co, or Ni) on various carbon supports with high catalyst loading is reported, featuring a unique bimetallic compound that evenly decomposes on carbon surface and forms uniformly sized intermetallic nanoparticles with a nitrogen-doped carbon protection layer.
