Improving the photoelectrochemical water splitting performance of CuO photocathodes using a protective CuBi2O4 layer
Autor: Nguyen Hoang Lam, Nguyen Tam Nguyen Truong, Nam Le, Kwang-Soon Ahn, Younjung Jo, Chang-Duk Kim, Jae Hak Jung
Publikováno v: Scientific Reports, Vol 13, Iss 1, Pp 1-12 (2023)
Abstract A heterojunction photocathode of CuO and CuBi2O4 grown on an FTO substrate (FTO/CuO/CuBi2O4) was synthesized using hydrothermal method followed by spin coating and annealing to overcome the bottlenecks encountered by CuO in photoelectrochemi

Facile Synthesis of Microsphere-like Co0.85Se Structures on Nickel Foam for a Highly Efficient Hydrogen Evolution Reaction
Autor: John Anthuvan Rajesh, Jae-Young Kim, Soon-Hyung Kang, Kwang-Soon Ahn
Publikováno v: Micromachines, Vol 14, Iss 10, p 1905 (2023)
Microsphere-shaped cobalt selenide (Co0.85Se) structures were efficiently synthesized via a two-step hydrothermal process. Initially, cobalt hydroxide fluoride (Co(OH)F) microcrystals were prepared using a hydrothermal method. Subsequently, Co0.85Se

Rationally Designed Bimetallic Co–Ni Sulfide Microspheres as High-Performance Battery-Type Electrode for Hybrid Supercapacitors
Autor: John Anthuvan Rajesh, Jong-Young Park, Ramu Manikandan, Kwang-Soon Ahn
Publikováno v: Nanomaterials, Vol 12, Iss 24, p 4435 (2022)
Rational designing of electrode materials is of great interest for improving the performance of battery-type supercapacitors. The bimetallic NiCo2S4 (NCS) and CoNi2S4 (CNS) electrode materials have received much attention for supercapacitors due to t

Fabrication and Characterization of the Broccoli-like Structured CuO Thin Films Synthesized by a Facile Hydrothermal Method and Its Photoelectrochemical Water Splitting Application
Autor: Nguyen Hoang Lam, Nguyen Tam Nguyen Truong, Chau Thi Thanh Thuy, Mohaseen S. Tamboli, Asiya M. Tamboli, Jinjoo Jung, Kwang-soon Ahn, Chang-Duk Kim, Jae Hak Jung
Publikováno v: Metals, Vol 12, Iss 3, p 484 (2022)
CuO thin films with broccoli-like structure were prepared using a facile hydrothermal method to construct photocathodes for water-splitting application. The morphological, structural, and optical properties of thin films were characterized and measur

Semi-Polycrystalline–Polyaniline Empowered Electrochemical Capacitor
Autor: Neelima Mahato, Debananda Mohapatra, Moo Hwan Cho, Kwang Soon Ahn
Publikováno v: Energies, Vol 15, Iss 6, p 2001 (2022)
We report on the formation of semi-polycrystalline polyaniline, a novel electroactive polymeric material synthesized by a modified surfactant-free chemical route and its enhanced electrochemical capacitive behavior. The material exhibits uniformly ar
