“…[12,40] Thea bove XPS resultsc orroborate the successfuli ncorporation of ZnIn 2 S 4 andM oSe 2 into the hybrid system.F urthermore, according to the valence band (VB) XPS spectrum (Figure 5f), the VB positiono fZ nIn 2 S 4 is determined to be + 1.50 eV and combined with the earlier UV/Vis results, this infers as uitable conduction band (CB) edge position (À1.2 eV) for H 2 evolution. [8,9,[13][14][15][16] The photocatalytic H 2 activity of pristine ZnIn 2 S 4 in our current work can be attributed to the uniqueh ierarchical architectures assembled by ultrathin layers (Figure 2). As plotted in Figure 6a, pristine MoSe 2 evolves an egligible amount of H 2 .P ure ZnIn 2 S 4 features an extraordinary photocatalytic activity, giving aH 2 evolution rate of 1023 mmol g À1 h À1 ,w hich surpasses most of the previously reported pristineZ nIn 2 S 4 materials.…”

“…[1][2][3][4][5][6] Among the reporteds emiconductormetal-sulfide photocatalystsw ith visible-light responses, af ascinating ternary chalcogenide, namely ZnIn 2 S 4 ,h as spurred a thriving area of research with attractive features such as as uitable band gap, non-toxicity,h igh chemical stability,a nd excellent catalytic activity,w hich render ZnIn 2 S 4 ag ood alternative to the highly poisonous CdS for visible light photocatalytic H 2 production. [7][8][9][10][11] Cocatalyst-modified ZnIn 2 S 4 has been regarded as ap ropitious strategy for enhancing photocatalytic H 2 evolution owing to the fact that the modification of cocatalysts can inhibitt he recombination of the photoexcited electronhole pairs, lower the overpotential for the H 2 evolutiona ctivity, and also provide the active reduction sites for H 2 evolution to avoid undesired back reactions. [12] Generally, noble metals such as Pt have been used as effectivec ocatalysts to modifyp ristine ZnIn 2 S 4 for H 2 evolution.…”

“…[30][31][32] Thus the high-energy (002) facets are expected to be more active than the others. The direct band gap between VBM and CBM is calculated to be 3.40 eV, with an expected diminution that is a common feature for DFT calculations 33 . 6a.…”

“…The studies by Shen et al [7] and Chaudhari et al [8] have revealed that ZnIn 2 S 4 was active for photocatalytic H 2 generation under visible light irradiations. However, the smaller band gap of ZnIn 2 S 4 (2.06-2.58 eV) [9,10] can reduce the photoactivity by increasing the recombination rate between electrons and holes [11].…”
