“…Similarly, the strong diffraction peaks of Ag 3 PO 4 at 2q ¼ 33.29 and 36.59 correspond to the (210) and (211) crystal planes of Ag 3 PO 4 (PDF#06-0505). 18,19 The strong diffraction peaks at 2q ¼ 30.960 and 44.346 are the characteristic peaks of the ( 200) and ( 220) crystal planes of AgBr (PDF#06-0438), [20][21][22] respectively. In addition to the strong signal peaks of Ag 3 PO 4 and AgBr, the diffraction peaks of the HAP (002) and (211) crystal planes (2q ¼ 25.88 and 31.77 ) also appear in the spectra of Ag 3 PO 4 /AgBr/ HAP.…”

“…However, the characteristic diffraction peaks of silver phosphate (JCPDS PDF #06-0505) appear in all the composites after the addition of silver ions (Figure 1b). For example, strong diffraction peaks appear at 2θ = 33.29 • and 36.59 • , corresponding to the (210) and (211) crystal planes of Ag 3 PO 4 , respectively [26,27]. However, only a weak signal of HAP was observed at 31.77 • .…”

A novel ternary Ag3PO4/g-C3N4/hydroxyapatite photocatalyst was prepared, and its morphology, composition and structure were characterized by X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy, high-resolution transmission electron microscopy, and electron spin resonance, etc. The results show that g-C3N4 is evenly dispersed in the interior of hydroxyapatite, forming a homogeneous composite, and significantly improves the band gap structure of the material as a whole. Ag3PO4/g-C3N4/hydroxyapatite has good electron transfer ability and an appropriate energy band structure, which shows that the material has a good degradation effect and stability. Finally, based on the characterization and experimental results, a possible Z-scheme mechanism was proposed, and the active species involved in the reaction are mainly O2− and h+.

“…It is noteworthy that in determining catalyst performance, the interaction between metal and support plays an essential role [201,202]. The most investigated supports in the literature to immobilize nanoparticles are zeolites [203,204], metal oxides [205,206] silica spheres [207,208] and alumina [209,210]; nanomaterials have also been largely immobilized in polymeric materials, adding value to waste that is normally dumped into the environment, causing problems [199,211,212]. Therefore, encouraging the choice of support based on polymeric materials is a topic of great importance.…”

Conversion of Plastic Waste into Supports for Nanostructured Heterogeneous Catalysts: Application in Environmental Remediation

Plastics are ubiquitous in our society and are used in many industries, such as packaging, electronics, the automotive industry, and medical and health sectors, and plastic waste is among the types of waste of higher environmental concern. The increase in the amount of plastic waste produced daily has increased environmental problems, such as pollution by micro-plastics, contamination of the food chain, biodiversity degradation and economic losses. The selective and efficient conversion of plastic waste for applications in environmental remediation, such as by obtaining composites, is a strategy of the scientific community for the recovery of plastic waste. The development of polymeric supports for efficient, sustainable, and low-cost heterogeneous catalysts for the treatment of organic/inorganic contaminants is highly desirable yet still a great challenge; this will be the main focus of this work. Common commercial polymers, like polystyrene, polypropylene, polyethylene therephthalate, polyethylene and polyvinyl chloride, are addressed herein, as are their main physicochemical properties, such as molecular mass, degree of crystallinity and others. Additionally, we discuss the environmental and health risks of plastic debris and the main recycling technologies as well as their issues and environmental impact. The use of nanomaterials raises concerns about toxicity and reinforces the need to apply supports; this means that the recycling of plastics in this way may tackle two issues. Finally, we dissert about the advances in turning plastic waste into support for nanocatalysts for environmental remediation, mainly metal and metal oxide nanoparticles.
