“…The analysis for degradation revealed that the newly synthesized Sr-doped TiO 2 composite had a higher photocatalytic activity, which resulted in enhanced degradation efficiency up to 96%, within 60 min, and moreover, the doping of strontium with TiO 2 enhanced the quantum efficiency by inhibiting the recombination of photo developed charge carriers (Sood et al 2015). Hidayanto et al (2017) used the sonochemical method for the preparation of nitrogen (N) (5-9 wt%)-doped TiO 2 nanocomposites. The resulting particles were observed having a size of 21.42 nm and a polycrystalline structure with increased photocatalytic activity for methylene blue dye (20 ppm) degradation (0.024 ppm min −1 ), as compared to bare TiO 2 (Hidayanto et al 2017).…”

Fabrication, functionalization and performance of doped photocatalysts for dye degradation and mineralization: a review

Textile wastewaters contain refractory dyes that cause pollution and socioeconomic issues, thus calling for efficient remediation techniques such as photocatalysis. We review the fabrication, functionalization, performance and limitations of doped catalysts for degrading and mineralizing dyes. We present developments in photocatalyst immobilization and photocatalytic reactor design. Methods such as microwave irradiation, sonication and use of ionic liquids are emerging for the preparation of doped photocatalysts. Whilst single-dye systems have been extensively studied, there is limited knowledge on multipledye systems. Immobilization of photocatalysts is gaining popularity for large-scale application, but faces issues of erosion, corrosion, mechanical strength and structure integrity. Ecotoxicological studies are required in real environments to validate the potential applications of nanostructured doped photocatalysts.

“…Therefore, the enormous energy of sunlight could be harnessed with this technology. The modification of N-doped TiO2 (Hidayanto, Sutanto, Mukholit, Wibowo, & Irwanto, 2017;Pandiangan, Sutanto, & Nurhasanah, 2018;Sutanto et al, 2017), Fe-TiO2 (Nasralla, Yeganeh, Astuti, Piticharoenphun, & Šiller, 2018), and defective TiO2 nano-powder (Ariyanti, Mills, Dong, Yao, & Gao, 2017), have been prepared to fulfil this purpose. However, low activity has occurred using these materials.…”

The Ag3PO4 photocatalyst has been developed to degrade the organic pollutant due to its highly active responsive under visible light irradiation. The properties of Ag3PO4 may depend on design and preparation. Starting materials and co-precipitation conditions would significantly affect the properties of the product. The controlled defect of this photocatalyst may lead to improve catalytic activity. Here, the unique properties of phosphate deficiency in Ag3PO4 were created using the starting material of KH2PO4 and AgNO3 under a mixed solvent of water and ethanol. AgNO3 solution with the ethanol percentages of 0%, 25%, 50%, 75% and 90% was added to KH2PO4 aqueous solution. The photocatalysts were characterized using XRD, DRS, SEM, and XPS. The changes in morphology can be observed from the tetrahedral to the sphere which has smaller particles. The increased atomic ratio of Ag/P and Ag/O suggests that the silver ion enrichment in Ag3PO4 has been created. The activity of Ag3PO4 for Rhodamine B elimination increased by 4.3 times higher compared to that of the pristine Ag3PO4. The enhanced photocatalytic activity might be caused by the smaller particle size and higher silver ion content on the surface of Ag3PO4.

“…Today silver orthophosphate has been developed as a photocatalyst for dye removal under visible light exposure due to owing small bandgap energy of 2.43 eV, strong photooxidation, and high quantum yield [1,2]. This material can be an alternative photocatalyst that is active in visible light in addition to popular photocatalysts such as N-TiO2 [3][4][5]. The modifications of morphology in Ag3PO4 photocatalyst have been applied to improve their photocatalytic activity [6].…”

The Enhanced Photocatalytic Properties of Silver Phosphate Synthesized Under Mangosteen Peel Extract Solution

et al. 2021

The synthesis of silver phosphate (Ag3PO4) photocatalyst has been widely developed for organic pollutant degradation. However, the large particle of this photocatalyst limits the photocatalytic activity. The smaller particle size of the Ag3PO4 photocatalyst was successfully prepared using the starting material of AgNO3 and Na2HPO4.12H2O under mangosteen peel extract solution. The starting materials were dissolved in mangosteen peel extract solutions prepared at the concentration of 1% (w/v). The reaction of silver nitrate and phosphate solution was conducted at room temperature. The samples of pristine Ag3PO4 and Ag3PO4 prepared under mangosteen peel extract were studied using XRD, DRS, SEM, BET, and FTIR. All photocatalytic activities were evaluated using Rhodamine B photooxidation under blue light irradiation (LED, 3 Watt). The results showed that the mangosteen peel extract significantly decreased the particle size, lowered the bandgap energy from 2.12 to 2.00 eV, and increased the crystallinity of Ag3PO4. The interaction of xanthones from mangosteen peel extract solution with silver ion might affect the growth particle of Ag3PO4, and inhibit the agglomeration leading to small particle size, more uniform distribution, high crystallinity, and low bandgap energy. These properties enhanced the photocatalytic activity up to 2.9 times higher compared to the sample without the treatment of mangosteen peel extract.
