Recent advances in photocatalytic treatment of pollutants in aqueous media

Deactivation and Regeneration of NaTaO3 Photocatalyst in Cooperating Dehydrogenation Coupling of Isopropanol and Hydrogenation Coupling of Acetone Reaction System

“…Given that photocatalysis is environmentally friendly and can effectively solve energy and environmental problems brought by traditional chemical engineering , it has been extensively adopted in various applications, such as photocatalytic hydrogen production , photocatalytic organic synthesis and pollutant disposal . Numerous research and reports on the development of new photocatalytic materials, modification of photocatalysts and design of high‐efficiency photocatalytic reaction have been conducted.…”

Photodegradation of Binary Azo Dyes Using Core-Shell Fe<sub>3</sub>O<sub>4</sub>/SiO<sub>2</sub>/TiO<sub>2</sub> Nanospheres

“…nanoparticles (MNPs) were prepared as described in our previous work [20]. MNPs were obtained by dissolving 3.3 g of FeSO 4 •7H 2 O and 2 g of NaNO 3 in 50 mL of distilled water. Then, 20 mL of NaOH solution (2.5 M) was poured into the mixture as it was heated up to 80˚C.…”

“…However, they also have disadvantages, such as the recombination of a generated redox environment, their absorption of a small amount of the UV light irradiation, a large band gap, and low selectivity [4] [5]. Therefore, TiO 2 -based semiconductors have been of great interest, and great efforts have been made to fabricate and design an ideal structure for TiO 2 -based semiconductors to improve the efficiency of the TiO 2 nanoparticles.…”

Highly efficient pollutant removal of graphitic carbon nitride by the synergistic effect of adsorption and photocatalytic degradation

“…Photocatalysis based on the conversion of solar into chemical energy has been regarded to be one of the most promising technologies to remove environmental pollutants. 5,6 Ever since the photocatalytic degradation of organic pollutants in aqueous suspensions has been reported by Carey et al in 1976, 7 there has been substantial development in the fabrication of highly efficient semiconductor-based photocatalysts. [8][9][10] Recently, graphitic carbon nitride (g-C 3 N 4 ) has been considered as the next generation photocatalyst and a step towards achieving sustainability for articial photosynthesis and environmental remediation since the pioneering work has been reported in 2009.…”

“…1,2 To date, a number of treatments, such as biodegradation, 3 adsorption, 4 and photocatalytic degradation, 5 have been studied to remove organic pollutants in water. Photocatalysis based on the conversion of solar into chemical energy has been regarded to be one of the most promising technologies to remove environmental pollutants.…”
