“…The sonochemical approach is a relatively simple and environmentally friendly method in which an ultrasonic vibration bath is utilized to fabricate the materials (Sutanto et al 2017). Sood et al (2015) utilized the hydrothermal fabrication method in combination with an ultrasonic method for the synthesis of strontium-doped TiO 2 NPs.…”

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.

“…The commonly used photocatalyst is titanium dioxide or titania (TiO2). This material is widely used due to its high efficiency, affordability, non-toxicity, inert-properties and biological photo stability 4,5 . There have been several attempts to improve the ability of TiO2 materials, e.g., through the synthesis of TiO2-nanocarbon composites.…”

In this paper, silver-doped titania (TiO2-Ag) powders have been synthesized with Ag variants using a simple sonochemical method. The prepared samples were identified using X-ray diffractometry (XRD) and scanning electron microscopy (SEM) to investigate the crystal structure and morphology, respectively. All samples showed the polycrystalline anatase phase and the plane exhibited the (101) dominant orientation. The smallest crystallite sample size of about 14.9 nm was obtained with a 3% Ag doping (TAg3). At higher Ag concentrations, the metal peaks could be detected at 44.3° and 64.4°. SEM images showed that all samples were agglomerated except the TAg3 sample with the lowest surface area of the active sites. Photocatalytic activity was carried out using Direct Blue 71 (DB71) as an organic pollutant. TAg4 exhibited the highest activity under ultraviolet (UV) irradiation with a degradation rate of 0.01 ppm/min. Results suggest that our TiO2-Ag photocatalyst performed well when prepared by a simple sonochemical method.

“…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.
