Few-layered MoS2 vertically aligned on 3D interconnected porous carbon nanosheets for hydrogen evolution

Autor: Dongjin Ko, Minsik Hwang, Bingyi Yan, Chai Hua, Xuanzhen Jin, Yuanzhe Piao, Wang Zhang, Juhyung Choi, Kwang-dong Seong, Jong Min Kim

Publikováno v: Applied Catalysis B: Environmental. 248:357-365

MoS2 has been considered as a non-precious alternative to platinum based electrocatalyst for electrochemical hydrogen evolution. Since most of the active site exists on the edges of MoS2, a material design that could increase the exposure of the edge

Fluoride ion-mediated morphology control of fluorine-doped CoFe2O4/graphene sheet composites for hybrid supercapacitors with enhanced performance

Autor: Xuanzhen Jin, Minsik Hwang, Juhyung Choi, Kwang-dong Seong, Yuanzhe Piao, Jeongmin Kang, Jong Min Kim

Publikováno v: Electrochimica Acta. 279:241-249

A one-pot facile hydrothermal synthesis of fluorine-doped CoFe2O4 sphere (FS-CoFe2O4)/graphene sheet (GS) composites, based on the Ostwald ripening mechanism, is presented in this work. Incorporation of fluorine in CoFe2O4/GS improves ion diffusion b
