“…The results yielded straight lines as shown in Fig. 7 confirmed the pseudo first-order kinetic reaction [13,24,39] in IC dye of the photodegradation process with the rate constants were 1.1725 h −1 , 0.4367 h −1 and 0.1823 h −1 for the TNR_5 wt%, TNR_10 wt% and TNR_15 wt% sheets, respectively. Moreover, the efficiency of this 3D porousstructured TNR_5 wt% hybrid sheet was also compared with sheets of the same type previously reported from our group [30][31][32].…”

Due to the high efficiency of photocatalytic process for the environmental treatments, titanium dioxide (TiO 2 ) is a popular used as photocatalyst material. However, the practical uses of TiO 2 in powder form have some drawbacks as well as the difficult reusability. In this work, 3D porous-structured TiO 2 @natural rubber (TNR) hybrid sheets with high photocatalytic performance were presented. TNR hybrid sheets prepared by a facile and low-cost method, which is based on the mixing of natural rubber (NR) latex (60% high ammonia) and ammoniacal TiO 2 (P25) suspension, followed by vacuum filtration through a sintered glass template to make a 3D porous network structure on the surface of the sheets. The obtained TNR sheet samples were characterized by scanning electron microscopy (SEM), energy dispersive X-ray spectrometer (EDX), X-ray diffractometer (XRD) and reflection Fourier transformed infrared spectroscopy (FT-IR) techniques. The results showed that the surface morphologies of TNR hybrid sheets appeared as porous-structured which had high roughness and with various tiny pores on the surface. The photocatalytic properties of the prepared TNR hybrid sheets were tested using indigo carmine (IC) dye under UV light irradiation. It was found that the highest photodegradation efficiency was achieved with the TNR_5 wt% hybrid sheet sample. Compared with the sheets reported in previous works, the TNR sheet shows higher efficiencies than those sheets due to its higher amount of TiO 2 particles at the surface, more porous structure with high rough surface, and abundance of tiny pores on the TNR sheet surface. Moreover, the recyclability and stability of TNR sheet indicated that upon using 10 cycles (remains 98% efficiency), in which the stability of the sheet surface well-confirmed by SEM and XRD techniques, as well. From above the study, this 3D porous-structured TNR hybrid sheet could be a new alternative strategy for the water or wastewater treatment in industry concerning with the easy use, recovery, reusability and stability of the photocatalysts.

“…Similarly, Thanh et al [148] studied the effect of ZnO-modified TiO 2 nanocomposites on the heterogeneous photocatalytic degradation of amoxicillin and found that the degradation and mineralization rates of amoxicillin were improved. To improve photocatalytic efficiency, a variety of catalytic materials have been used in photocatalytic research, including metal oxides and sulfides (TiO 2 , SnO 2 and CdS), metal semiconductors (BiOBr, BiOCl, BiVO 4 and GdVO 4 ) [149][150][151][152] and non-metallic semiconductors (gC3N4) [153]. However, among many catalysts, TiO2 and BiVO 4 are widely used in the removal of various antibiotics, such as tetracycline [154], ciprofloxacin [155,156], penicillin [157], norfloxacin [158], sulfamethoxazole [159], oxytetracycline [160], etc.…”

Antibiotics are highly effective bactericidal drugs that are widely used in human medicine, aquaculture and animal husbandry. Antibiotics enter the aquatic environment through various routes due to low metabolic levels and increased use. Not only are antibiotics inherently toxic, but the spread of potential drug resistance introduced has been identified by the World Health Organization as one of the major threats and risks to global public health security. Therefore, how to efficiently remove antibiotics from water and eliminate the ecological safety hazards caused by antibiotics has been a hot topic in recent years. There are various research methods for decontaminating water with antibiotics. This paper reviews the research and application of various biological, physical, chemical methods and combined processes in antibiotic pollution control. Moreover, this paper describes the degradation mechanism, removal efficiency, influencing factors and technical characteristics of different antibiotics by various methods in detail. Finally, an outlook on future research in antibiotic removal is provided to help promote the development of antibiotic removal technology.
