“…Metal oxides such as TiO 2 , − ZnO, − Fe 2 O 3 , − Bi 2 O 3 , , ZrO 2 , − CuO, , NiO, , and CeO 2 , have been intensively explored as effective photocatalysts to degrade various organic and inorganic pollutants in wastewater. In particular, nanosized metal oxide photocatalysts exhibit good degradation properties owing to their well-known nanoeffects.…”

Surfactant-Free Aqueous Dispersions of Shape- and Size-Controlled Zirconia Colloidal Nanocrystal Clusters with Enhanced Photocatalytic Activity

et al. 2019

Colloidal nanocrystal clusters (CNCs) are formed by clustering nanocrystals into secondary structures, which represent a new class of materials and have attracted considerable attention, owing to their unique collective properties and novel functionalities achieved from the ensembles in addition to the properties of each individual subunit. Here, we design a simple route to prepare aqueous dispersions of highly stable ZrO2 CNCs with tunable shape and size without modification. ZrO2 CNCs are composed of many ZrO2 nanocrystals each with a size of about 7 nm and possess a mesoporous structure. Both cube-like and star-like shapes of CNCs can be achieved by using different alkaline sources, while the size of CNCs can be adjusted by changing the hydrothermal time. The as-prepared aqueous dispersions of ZrO2 CNCs display an enhanced photocatalytic activity in the degradation of rhodamine B (RhB), compared with ZrO2 nanodispersions. More interestingly, star-like ZrO2 CNCs show better photocatalytic degradation properties than those of cube-like counterparts and even commercial P25. Furthermore, ZrO2 CNCs are easily recycled and can be used for the degradation of a range of dye systems.

“…a-Fe 2 O 3 nanomaterials possess several interesting and excellent physical and chemical properties which include its n-type conductivity, low-band gap energy (E g = 2.1 eV), cost effective synthesis, high corrosion resistivity, biocompatibility, non-toxicity, environmental-benign, and so on [1][2][3][4][5][6]. Because of these interesting properties, it is widely used for several high-technological applications such as chemical sensors [7][8][9] catalyst [10], magnetic devices [11], water splitting [12], and biomedical applications [13].…”

“…To solve this problem, the sedimentation properties of the photocatalyst should be taken into consideration [10]. However, the larger a photocatalyst particle is, the lower its photocatalytic activity will be, due to the more severe recombination of photo-generated carriers [11].…”

Photocatalytic degradation of fipronil in water by silver-modified lithium vanadium phosphate spheres under visible light irradiation

et al. 2015

A novel visible light-driven photocatalyst, lithium vanadium phosphate sphere (LVPS), was prepared by a ball-milling method. For enhancing the photocatalytic performance, LVPS was further modified with silver (ALVPS) by a UV-light photoreduction method. After modification, the crystalline phase of LVPS did not change, however, the UV-Vis diffuse reflectance spectrum of ALVPS was extended to 656 nm, which greatly improved its photoabsorptivity for visible light and enhanced its electron donating capacity. Under the irradiation of sunlight or visible light (>400 nm), ALVPS can rapidly remove fipronil (a persistent organic pollutant, 5 mg L 1 ) from aqueous solution. More than 99.7% of fipronil was removed by ALVPS after 0.5 h of irradiation, yielding a much higher removal rate than those achieved by nano-TiO 2 and Bi 2 O 3 . Photo-generated carrier trapping experiments were conducted to elucidate the photocatalytic degradation mechanism further. Hydrogen peroxide and potassium bromate suppressed the photocatalytic activity of ALVPS, while superoxide dismutase and sodium azide reinforced it, verifying that photo-generated electrons played a key role in the photochemical reaction. lithium vanadium phosphate, sphere, visible light irradiation, photocatalysis, degradation
