Abstract

The rational design of novel hierarchical MoS2/CoS2 heterogeneous nanotube arrays as self-supported and pH-universal electrocatalysts for efficient HER.

Pore Surface Engineering of Covalent Triazine Frameworks@MoS2 Electrocatalyst for the Hydrogen Evolution Reaction

“…[45] Apart from Tafel slope, electrochemical active area is another important parameter to characterize the catalytic activity of electrocatalysts and has ad irectl inear relationship with the double-layerc apacitance. [49,50] It is worth noting that the SEM images of CTFs@MoS 2 -5 after stability measurement do not have perceptible variation in the morphology( Figure S19). The double-layer capacitance was calculated according to cyclic voltammetry, which was carriedo ut at various scan rates in 0.05-0.35 Vv s. the reversibleh ydrogen electrode (RHE) non-faradic region.…”

“…It is indicated that CTFs@MoS 2 -5h ave the excellent stabilityf or high-efficiency HER. [49,50] It is worth noting that the SEM images of CTFs@MoS 2 -5 after stability measurement do not have perceptible variation in the morphology( Figure S19). The TEM analysis also proved the crystal structures of the CTFs and MoS 2 were consistent with the original ones.…”

A flower-like CoS2/MoS2 heteronanosheet array as an active and stable electrocatalyst toward the hydrogen evolution reaction in alkaline media

“…Previous studies unveiled that the well-exposed transition metal related active sites could act as an exceptional H 2 O dissociation center while the Mo-related active sites demonstrate superior adsorption capability toward H. 4,13,57,66 The formation of well-exposed CoS 2 /MoS 2 heterointerfaces may simultaneously promote the adsorption towards H in alkaline media and strengthen the dissociation of H 2 O molecules, which require further theoretical investigation. 67,68…”

Metal–organic framework derived nanomaterials for electrocatalysis: recent developments for CO2 and N2 reduction

“…At first, a Co-based MOF has been grown over carbon cloth electrodes. Thereafter, the MOF was subjected to an hydrothermal reaction to convert it into the final MoS 2 /CoS 2 nanotube array structure [ 51 ]. Liang et al shown phosphorization of bimetallic MOF to derive Ni 2 P-CoP nanostructure (As can be seen in the illustrative synthetic scheme and transmission electron microscopy (TEM) images in Fig.…”
