“…As shown in Figure 6a, the XPS survey of(Au/Ta3N5)/CdS indicated the existence of Au, Ta, N, Cd and S elements in the sample, which indicates the successful synthesis of (Au/Ta3N5)/CdS composites. The Au 4f spectrum in Figure 6b displayed two peaks at 84.2 and 87.9 eV, attributing to the Au 4f7/2 and Au 4f5/2, respectively [25]. The Ta Ta 4f5/2 and 4f7/2 components are 27.0, 25.2 eV, may be attributed to Ta 5+ .…”

As non-noble metal co-catalysts, Nitrides have received extensive attention for their high efficiency and low cost in photocatalytic hydrogen production. In this study, we develop a novel composite co-catalyst of Au/Ta3N5 that significantly enhanced the photocatalytic hydrogen production activity of CdS. The activity of photocatalyst (Au/Ta3N5)/CdS is 7.3 times of bare CdS and 2.2 times of Ta3N5/CdS. The proper capacitance and enhanced activity of Ta3N5 demonstrates the capacitance catalysis effect of Ta3N5, which improves the charges separation and storing of the photoexcited electrons from CdS. Au acts as an active site for proton reduction to further improve the activity.

Increasing the active site of redox reactions on the surface of photocatalysts and accelerating the separation and transfer of photogenerated electron‐hole pairs are effective methods to improve the hydrogen evolution of composite photocatalysts. Non‐precious metal Ni photo‐deposition is anchored in situ on the ZnIn2S4 surface to generate the cocatalyst Ni(OH)2, which improves the photocatalytic hydrogen evolution performance of the composite sample. Under visible light irradiation, the ZnIn2S4 semiconductor stimulates photon‐generated carriers. Ni2+ acts as the defect center of photogenerated electron‐hole pairs to promote the separation of carriers. It serves as the capture site of light‐generated holes to reduce the carrier recombination rate so that the light‐generated electrons on the ZnIn2S4 surface promote H+ reduction in H2. Ni(OH)2 provides the active site for oxidation reaction on the surface of semiconductor materials, allowing the carrier to be consumed faster and improving the photocatalytic stability of semiconductor materials. The addition of 2 wt% Ni2+ resulted in a hydrogen evolution rate of 10 066 µmol·g−1 ·h−1 for ZnIn2S4/Ni(OH)2, which was 2.5 times higher than that of pure ZnIn2S4. This paper presents a reference case for enhancing the stability of sulfide to promote its photocatalytic hydrogen evolution.

“…However, the photocatalytic performance of g-C 3 N 4 is often limited by the rapid recombination of photo-generated electron-hole pairs and low light absorption capacity [19]. To overcome these limitations, the construction of heterostructures by coupling g-C 3 N 4 with other semiconductors has been widely explored [20,21]. In this study, silver phosphate (Ag 3 PO 4 ) and magnetite (Fe 3 O 4 ) are promising candidates Sustainability 2023, 15, 13279 2 of 14 due to their strong visible light absorption and magnetic properties, respectively [22][23][24][25].…”

In this study, a novel Fe3O4/Ag3PO4/g-C3N4 magnetic composite photocatalyst was successfully synthesized, tailored specifically for the visible light-driven photocatalytic degradation of sulfonamide antibiotics, more precisely, sulfamethazine (SMZ). To analyze the fabricated samples, characterization techniques such as X-ray diffraction (XRD), scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FT-IR), photoluminescence spectroscopy (PL), and UV-vis diffuse reflectance spectra (UV-vis) were systematically employed. The composite showcased efficient visible-light absorption and charge separation, with its peak photocatalytic performance recorded at a solution pH value of 6.0. Significantly, the Fe3O4/Ag3PO4/g-C3N4 magnetic composite photocatalyst displayed excellent stability and recyclability, consistently maintaining a high degradation efficiency of over 97% even after five consecutive cycles. Further experimentation with radical scavengers confirmed a significant decrease in photocatalytic activity, establishing that superoxide radicals (•O2−) and photo-generated holes (h+) are the primary active species during the degradation of SMZ. Overall, it provides a crucial understanding regarding the photocatalytic decomposition of sulfonamide antibiotics using magnetic composite photocatalysts. It also emphasizes the promising potential of the Fe3O4/Ag3PO4/g-C3N4 composite for tangible applications in environmental remediation.
