“…The coupling with NiO exhibited mixed effects on the deactivation of various bacteria, suggesting the distinct interaction of bacteria with the ternary composite. The high performance of GCN/ZnO/NiO toward TC degradation was observed at pH 6 and unidirectional charge transfer with NiO as mediator promoted the charge carrier separation process .

Heterostructuring the g-C 3 N 4 (GCN) with wide gap oxide photocatalysts is of prominent interest as they can harvest photons spanning the UV−visible region. In this regard, GCN/ZnO have garnered remarkable attention due to their admirable structure, optical, dimensional anisotropy, and electronic properties. The 2D sheet-like structure of GCN can serve as a suitable substrate for the growth of distinct ZnO nanostructures under the multitude of reaction conditions. This review focuses on the progress in the rational design and interface engineering of GCN/ZnO to from Type-II and Z/S-scheme heterojunctions, followed by their relevant photocatalytic applications toward H 2 evolution, CO 2 reduction, pollutant degradation, and bacteria inactivation. The mechanism underlying the crystallization of GCN and ZnO together with their intimate contact in the composite are emphasized under the light of diverse preparation methods. The modification of GCN/ZnO with cocatalysts such as metals, alloy, semiconductors, and carbon materials to form ternary systems to highlight their advancements. The gap analysis and future prospectus of this intricate heterostructure concerning the challenges in synthetic approaches and the charge carrier dynamics are discussed. This review envisages the development of efficient GCN/ZnO-based heterostructures for multiscale applications.

“…Simultaneously, h + migrated from SE III (VB) to SE II (VB), and finally accumulated on SE I (VB), as illustrated in Figure 5(a). Dineshbabu et al [98] fabricated a novel ternary dual-type-II ZnO/ NiO/g-C 3 N 4 heterojunction nanocomposite. Compared with pristine ZnO and g-C 3 N 4 , the ZnO/NiO/g-C 3 N 4 nanocomposites showed enhanced performance in photocatalytic degradation of TC, because the more reactive species were generated in the system.…”

Photocatalytic degradation technology, using solar energy as the driving force, is considered the most possible alternative to remediate environmental pollution. And it is essential to find a stable and efficient photocatalyst. As promising semiconductor-based photocatalysts, Cu 2 O has acquired massive attention owning to its high conduction band energy, superior visiblelight response-ability, low cost, eco-friendly, and abundance. However, the application of origin Cu 2 O faces severe problems due to its photocorrosion and low photoinduced carrier separation. Consequently, it is necessary to improve its photo-stability and photocatalytic activity by carrying out numerous modification strategies, such as heterostructure construction. Herein, we first summarize the classification and operation principles of Cu 2 O-based type-II heterojunction. Then, the application of the Cu 2 O-based type-II heterojunction photocatalysts for the removal of tetracyclines, quinolones, and sulfonamides have been discussed. Finally, the pressing issues and perspectives in Cu 2 O-based type-II heterojunction photocatalysts application for degrading antibiotics have prospected.

“…However, synthesizing visible light active semiconductor materials is not sufficient as the recombination rate of charge carriers is very high due to the small band gap energy . This problem was addressed using various strategies, such as doping metals and nonmetals, , co-depositing metals on semiconductor surfaces, − and coupling of two or more semiconductors to create binary , and ternary , heterojunctions. A key strategy in photocatalytic processes for pollutant degradation is the construction of type-II heterostructure composite photocatalysts by coupling appropriate semiconductors. , …”

In this study, an effective type-II heterojunction CdS/AgI binary composite was constructed by an in situ precipitation approach. To validate the successful formation of heterojunction between AgI and CdS photocatalysts, the synthesized binary composites were characterized by various analytical techniques. UV−vis diffuse-reflectance spectroscopy (UV−vis DRS) revealed that heterojunction formation led to a red shift in the absorbance spectra of the CdS/AgI binary composite. The optimized 20AgI/CdS binary composite showed a least intense photoluminescence (PL) peak indicating highly improved charge carrier (e − /h + pairs) separation efficiency. The photocatalytic efficiency of the synthesized materials was assessed based on the degradation of methyl orange (MO) and tetracycline hydrochloride (TCH) in the presence of visible light. Compared to bare photocatalysts and other binary composites, the 20AgI/CdS binary composite showed the highest photocatalytic degradation performances. Additionally, the trapping studies showed that superoxide radical anion (O 2•− ) was the most dominant active species involved in photodegradation processes. Based on the results of active species trapping studies, a mechanism was proposed to describe the formation of type-II heterojunctions for CdS/AgI binary composite. Overall, the synthesized binary composite has tremendous promise for environmental remediation due to its straightforward synthesis approach and excellent photocatalytic efficacy.
