Effects of nitrogen-doping structural changes of spherical hollow graphene on the growth of MoS2+x nanosheets and the enhanced hydrogen evolution reaction

Control of the morphologies of molybdenum disulfide for hydrogen evolution reaction

“…However, there was no space for the MoS 2 NP to trap the nitrogen atoms. To the best of our knowledge, nitrogen doping could enhance the electrocatalytic properties of MoS 2 , as previously reported 51‐53 . The high‐resolution XPS (HRXPS) N 1 s spectra are shown in Figure 4.…”

“…To the best of our knowledge, nitrogen doping could enhance the electrocatalytic properties of MoS 2 , as previously reported. [51][52][53] The high-resolution XPS (HRXPS) N 1 s spectra are shown in The shapes and sizes of the different materials were carefully observed via FE-SEM at different scales -300 nm in Figure 5 and 1 μm in Figure S7. The FE-SEM images show the successful growth of the different morphologies of MoS 2 under different conditions of the reaction media.…”

MoS2 nanosheets grown on bowl-shaped hollow carbon spheres as an efficient electrochemical sensor for ultrasensitive determination of nephrotoxic aristolochic acids in Chinese traditional herbs

“…3e). 31 Fig. 3f shows the deconvoluted spectrum of S 2p, deconvoluted into two sets of peaks: S 2− 2p 3/2 and S 2− 2p 1/2 .…”

“…3e). 31 The smaller the diameter of the Nyquist semicircle, the smaller the electron transfer resistance, and the higher the conductivity of the electrode. 32 The EIS data were tted using an equivalent circuit in which R s is the solution resistance, and R CT is the electron transfer resistance.…”

Recent Progress in Graphene-Based Electrocatalysts for Hydrogen Evolution Reaction

“…Shen et al [ 124 ] investigated the effect of different nitrogen precursors on the structure of nitrogen-doped 3D spherical hollow graphene and the changes in HER based on this nitrogen-doped graphene structure. The results showed that the N-doping site can act as a nucleation and growth center for MoS 2+x .…”
