Facile synthesis of low crystalline MoS2 nanosheet-coated CNTs for enhanced hydrogen evolution reaction

Abstract

In this work, a networked MoS2/CNT nanocomposite has been synthesized by a facile solvothermal method. The as-prepared sample exhibits high catalytic activity for electrocatalytic hydrogen evolution.

Solvent-Assisted Oxygen Incorporation of Vertically Aligned MoS2 Ultrathin Nanosheets Decorated on Reduced Graphene Oxide for Improved Electrocatalytic Hydrogen Evolution

“…18 The peak intensity related to A 1g vibrational mode is about three times larger than that related to E 1 2g one. Additionally, the wide peak related to E 1 2g vibrational mode is responsible for the poor crystallization and rich defects along the 002 crystal planes, 19 as seen in Figure 1c and f. Previous studies confirmed that the frequency difference between the two peaks presented the number variation of (002) crystal-plane layers along the c-axis of MoS 2 nanosheets. 27,29 Our results show that the differences between the two dominant peaks are 30 and 26 cm −1 for O-MoS 2 and O-MoS 2 /rGO, respectively.…”

Two-Dimensional Material Molybdenum Disulfides as Electrocatalysts for Hydrogen Evolution

“…Similarly, Liu's group synthesized a MoS 2 /carbon nanotube (CNT) nanocomposite network by a facile solvothermal method. The SEM image of the MoS 2 / CNT composite is shown in Figure 6d [59]. Similar to the graphene sheets, the CNT could also provide a rapid electron transport channel from the less conducting MoS 2 to the electrodes.…”

Fabrication of FeOOH hollow microboxes for purification of heavy metal-contaminated water

“…18 To overcome this restriction, assembling these 2D FeOOH nanosheets into threedimensional (3D) hollow structures should be an efficient way to avoid agglomeration and retain the advantages of lamellar 2D nanosheets to a large extent. [19][20][21][22] In previous studies, numerous methods were utilized to fabricate hollow structures with well-defined interior voids and adequately exposed active sites for various applications, such as gas sensing, selective permeability and light degradation. [23][24][25] However, among these fabrication processes, the growth of desirable shells by using a sacrificial template was the most feasible approach, while the complicated synthetic conditions have restricted their production in large quantity.…”
