“…That for Sn 3d displayed in Figure 3b exhibited two peaks located at 486.38 and 494.72 eV respectively related to Sn 3d 5/2 and Sn 3d 3/2 , which were features of the Sn 4+ state in ZSH. 36 As for the deconvoluted O 1s peak in Figure 3c, two characteristic peaks centered at 529.84 and 531.18 eV were assigned to oxygen components in the Zn−Sn lattice (e.g., Zn−O and Sn−O) as well as chemisorbed oxygen species as −OH in ZSH, respectively. 37,38 Additionally, as shown in Figure 3d, the binding energies for S 2p and Bi 4f overlap, and thus, the correlation peaks were decomposed into four peaks.…”

The combination of piezoelectric catalysis and photocatalysis could effectively enhance the carrier separation efficiency and further improve the hydrogen production activity. However, piezoelectric polarization always suffers from a low polarization strength, which severely restricts its actual applications. In this study, we successfully synthesized a novel sulfur vacancy-rich Bi 2 S 3 /ZnSn (OH) 6 (BS-12/ZSH) piezo-photocatalyst for hydrogen evolution through water splitting. Notably, the piezo-photocatalytic hydrogen generation rate of the 8% BS-12/ ZSH catalyst (336.21 μmol/g/h) was superior to that of pristine ZSH (29.71 μmol/g/h) and BS-12 (21.66 μmol/g/h). In addition, the hydrogen generation for 8% BS-12/ZSH (336.21 μmol/g/h) under ultrasonic coupling illumination was significantly higher than that under single illumination (52.09 μmol/g/h) and ultrasound (121.90 μmol/g/h), owing to the cooperative interaction of the sulfur vacancy and piezoelectric field. Various characterization analyses confirmed that (1) the introduction of sulfur vacancies in BS-12 provided more active sites, (2) BS-12 with sulfur vacancies acted as a co-catalyst to accelerate the hydrogen production rate, and (3) the piezoelectric field eliminated the electrostatic shielding and offered an additional driving force, which effectively promoted the separation of electron−hole pairs. This research clearly reveals the synergistic effect between piezocatalysis and photocatalysis as well as offers a promising sight for the rational design of high-efficiency piezo-photocatalysts.
