“…While photocatalysis effectiveness is increased when UV light is utilized, numerous materials have been shown to be capable of visible light photodegradation of pharmaceuticals. 109,114,[116][117][118][119][120][121][122][123][124][125][126][127][128][129][130][131][132][133][134] Although power utilization of many visible light lamps is equivalent to that of low-pressure UV lamps, the lifetime of UV lamps is significantly lower. Furthermore, with the increased availability of LED lighting options, the power of using visible light photoreactors can be greatly reduced.…”

Increasing human activity, including commercial and noncommercial use of pharmaceuticals, personal care products, and agricultural products, has introduced new contaminants that can be challenging to remove with currently available technologies. Pharmaceuticals, in particular, can be especially challenging to remove from the water supply and can pose great harm to people and local ecosystems. Their highly stable nature makes their degradation with conventional water treatment techniques difficult, and studies have shown that even advanced treatment of water is unable to remove some compounds. As such, decontamination of water from pharmaceuticals requires the development of advanced technologies capable of being used in indirect and direct potable water reuse. In this review, we discuss pharmaceutical removal in indirect potable water treatment and how recent advancements in adsorption and photocatalysis technologies can be used for the decontamination of pharmaceutical-based emerging contaminants. For instance, new materials that incorporate graphene-based nanomaterials have been developed and shown to have increased adsorptive capabilities toward pharmaceuticals when compared with unmodified graphene. In addition, adsorbents have been incorporated in membrane technologies, and photocatalysts have been combined with magnetic material and coated on optical fibers improving their usability in water treatment. Advancements in photocatalytic material research have enabled the development of highly effective materials capable of degradation of a variety of pharmaceutical compounds and the development of visible-light photocatalysts. To understand how adsorbents and photocatalysts can be utilized in water treatment, we address the benefits and limitations associated with these technologies and their potential applicability in indirect potable water reuse plants.

“…Recently, considering the relative high cost of the common used electron mediators (e.g., Pt, Ag, and Au), a new generation of Z-heterojunctions without the electron mediators have been invented for wastewater treatment, which is named as the direct Z-scheme system [59]. For example, Lu et al [77] synthesized a CuInS 2 /Bi 2 WO 6 composite catalyst with a direct Z-scheme heterojunction via the in situ hydrothermal growth of Bi 2 WO 6 on the surface of CuInS 2 networks. The obtained composite photocatalysts with an optimal Z-scheme exhibited a superior visible light degradation performance of the tetracycline hydrochloride in water than that of the pristine CuInS 2 and Bi 2 WO 6 .…”

Serious water pollution and the exhausting of fossil resources have become worldwide urgent issues yet to be solved. Solar energy driving photocatalysis processes based on semiconductor catalysts is considered to be the most promising technique for the remediation of wastewater. However, the relatively low photocatalytic efficiency remains a critical limitation for the practical use of the photocatalysts. To solve this problem, numerous strategies have been developed for the preparation of advanced photocatalysts. Particularly, incorporating a semiconductor with various functional components from atoms to individual semiconductors or metals to form a composite catalyst have become a facile approach for the design of high-efficiency catalysts. Herein, the recent progress in the development of novel photocatalysts for wastewater treatment via various methods in the sight of composite techniques are systematically discussed. Moreover, a brief summary of the current challenges and an outlook for the development of composite photocatalysts in the area of wastewater treatment are provided.

“…The layer absorption coefficient of indium copper disulfide (CuInS 2 ) is about 10 À 5 cm À 1 , and the band gap is about 1.53 eV.. [18][19][20] Because it can effectively convert the energy of visible light, it has huge potential in photocatalytic field. However, CuInS 2 has poor photocatalytic activity, therefore, it is used for the combination with a semiconductor having a higher catalytic activity.…”

In this paper, CuInS2 was grown on the surface of flower‐shaped BiOBr by a two‐step hydrothermal method for the first time, and a direct Z‐scheme CuInS2@BiOBr heterojunction structure with close interface contact was successfully prepared. The formation of heterojunctions improves the efficiency of photogenerated carrier transport and separation. Under the visible light irradiation for 75 min, the optimal 5 wt % CuInS2@BiOBr composite material can degrade RhB to 97 %. Radical trapping experiment is shown that holes and superoxide radicals are the main active materials in photocatalytic processes, and a direct Z‐scheme photocatalytic mechanism is proposed.
