“…In particular, the conduction band positions for SnO2 and ZnIn2S4 are recorded at −0.14 eV and −0.58 eV, respectively, while their valence band positions are noted at 3.35 eV and 1.78 eV, respectively. [15,[44][45][46]. In addition, previous XPS O1s (Figure 4c) can verify that SnO2 nanoparticles and SnO2@ZnIn2S4 composites exhibited oxygen defects.…”

This research successfully synthesized SnO2@ZnIn2S4 composites for photocatalytic tap water splitting using a rapid two-step microwave-assisted synthesis method. This study investigated the impact of incorporating a fixed quantity of SnO2 nanoparticles and combining them with various materials to form composites, aiming to enhance photocatalytic hydrogen production. Additionally, different weights of SnO2 nanoparticles were added to the ZnIn2S4 reaction precursor to prepare SnO2@ZnIn2S4 composites for photocatalytic hydrogen production. Notably, the photocatalytic efficiency of SnO2@ZnIn2S4 composites is substantially higher than that of pure SnO2 nanoparticles and ZnIn2S4 nanosheets: 17.9-fold and 6.3-fold, respectively. The enhancement is credited to the successful use of visible light and the facilitation of electron transfer across the heterojunction, leading to the efficient dissociation of electron–hole pairs. Additionally, evaluations of recyclability demonstrated the remarkable longevity of SnO2@ZnIn2S4 composites, maintaining high levels of photocatalytic hydrogen production over eight cycles without significant efficiency loss, indicating their impressive durability. This investigation presents a promising strategy for crafting and producing environmentally sustainable SnO2@ZnIn2S4 composites with prospective implementations in photocatalytic hydrogen generation.

“…In addition, the characteristic peaks of Ti 2p3/2 and Ti 2p1/2 were also observed at the positions of 458.58 eV and 464.28 eV on the Ti 2p XPS profile of TBCN, which indicated that Ti MOF was successfully loaded on the BCN and Ti binds to O in the oxidation state IV to form Ti–O clusters during synthesis. 36 Finally, the elements of the three materials were analyzed from the full XPS spectra, and the results are shown in Fig. 3f.…”
