Engineering Ultrathin MoS2 Nanosheets on CoxP/Nitrogen‐Doped Carbon Nanocubes for Efficient Hydrogen Evolution

“…So far, MoS 2 has been utilized as shell unit to integrate with carbonaceous materials or metal sulfides to construct core-shell heterostructures with admirable catalytic properties. [7][8][9][10][11] Very recently, our group has prepared MoS 2 nanosheets vertically aligned on ZnCo/NC dodecahedra, and the HER activities can be well adjusted by varying the Zn/Co ratio. [12] In spite of these advances on the fabrication of MoS 2 -based heterostructures, the activity and stability of catalysts need to be further improved and it's still in great demand to exploit more suitable matrixes for functionally decorating MoS 2 nanosheets.…”

Synthesis of N, P dual‐doped MoS 2 on hollow carbon spheres for hydrogen evolution reaction

“…As presented for P 2p spectra in Figure 5D, the signals at 129.0 and 130.0 eV match with the p 2p 3/2 and p 2p 1/2 of PMo bonding. The signals at the bonding energy of 133.0 and 134.0 eV match with PC and PO, respectively 40,43 . Of note, the forming of PMo and PC bonds indicate the replacing of S atom in MoS 2 .…”

“…It can been seen that the surface of P‐MoS 2 @NCs‐2 is composed by the C, O, P, N, S, and Mo (Figure 5A), which is consistent with above EDS results. For the spectrum of C 1s in Figure 5B, the peaks located at 285.3, 286.2, and 286.8 eV correspond to the CP, CN, and CN, respectively 40,41 . The registered N 1 second peak show signals at 395.6, 398.3, and 399.8 eV (Figure 5C), which account for Mo‐N, pyridinic and pyrrolic states of N, respectively 42 .…”

In-situ Formation of Amorphous Co-Al-P Layer on CoAl Layered Double Hydroxide Nanoarray as Neutral Electrocatalysts for Hydrogen Evolution Reaction

“…There is an urgent demand for clean and sustainable energy resources to replace the traditional fossil fuels (Chow et al, 2003;Chu and Majumdar, 2012;Xie and Xie, 2015;Huang L. et al, 2019). Hydrogen has been regarded as one of the most ideal candidates because of its high energy density and zero-carbon emissions (Sun et al, 2018;Chi et al, 2019;Fei et al, 2020;Zhu et al, 2020), and abundant efforts have been devoted to exploring appropriate strategies for hydrogen production. Up to date, it is wellestablished that water electrolysis is a promising and environmentally friendly approach to produce highly pure hydrogen (Wang et al, 2018a;Hu et al, 2019;Chen et al, 2020a;Xue et al, 2020).…”
