Knack behind the high performance CdS/ZnS-NiS nanocomposites: Optimizing synergistic effect between cocatalyst and heterostructure for boosting hydrogen evolution

g‐C3N4/SnS2 van der Waals Heterostructures Enabling High‐Efficiency Photocatalytic Hydrogen Evolution

“…The electrochemical impedance (EIS) plots (Figure 5c) disclose that impedance arc radii of 15%C/S are obviously smaller than that of other samples, which also proves more electrons across the electrolyte interface of the composite sample. [54][55][56] Additionally, as verified by TRPL spectra (Figure 5d) and calculated summary parameters in Table S2, Supporting Information, 15%C/S exhibits a slower recombination rate and longer lifetime compared to that of SnS 2 and g-C 3 N 4 . Room-temperate PL spectra are performed to explore the carrier dynamics behavior.…”

“…7b and S7†). 51,52 Moreover, the Mott–Schottky curves for SnS 2 -160 displayed positive slopes (Fig. 7c) suggesting that the SnS 2 -160 NS sample is an n-type semiconductor with a flat-band potential ( E fb ) of around −1.09 V vs. Ag/AgCl (saturated KCl solution, E 0 = 0.198 V vs. NHE).…”

ZIF ‐67 derived hollow double‐shell core Co 3 O 4 modified g‐C 3 N 4 to construct p‐n heterojunction for efficient photocatalytic hydrogen evolution

“…At present, replacing traditional fossil energy with green energy to improve the environment has become a hot topic 1,2 . And among the many energy sources, hydrogen energy has been widely concerned because of its high combustion calorific value and environmental protection and renewable properties 3‐5 . However, industrialized large‐scale hydrogen production still has a long way to go.…”

“…1,2 And among the many energy sources, hydrogen energy has been widely concerned because of its high combustion calorific value and environmental protection and renewable properties. [3][4][5] However, industrialized large-scale hydrogen production still has a long way to go. On the contrary, as a renewable energy source, solar energy is inexhaustible.…”

“…sample gradually decreases. In Table3, the fluorescence lifetime of EY uses a single exponential fluorescence decay kinetic function(2), while the fluorescence lifetimes of g-C 3 N 4 , Co 3 O 4 , and CNCO-x (x = 1, 2, 3, 4, and 5) used the double exponential fluorescence decay kinetic function(3). And the average fluorescence lifetime of the catalyst was calculated using formula (4) 59,60.…”
