Ultrasound aided sonocatalytic degradation of Rhodamine B with graphitic carbon nitride wrapped zinc sulphide nanocatalyst

Enhanced sonocatalytic performance of PEG-modified hierarchical Cu 2 ZnSnS 4 microspheres in Methylene Blue degradation

“…The sonocatalytic dye degradation mechanism is mainly established on the "sonoluminescence" and ''hotspot" phenomenon. The ultrasound irradiation in aqueous solution can induce acoustic cavitation effect which consists on the nucleation, growth, and collapse of cavitation bubbles in the liquid medium, leading to the sonoluminescence and hotspot [32,33]. The synergistic effect between hotspot with extremely high temperature and sonoluminescence with a wide wavelength and sonocatalyst can produce electrons and holes in sonocatalyst, which ultimately resulted in the formation of reactive oxygen radicals [34].…”

Fe3O4@MIL-100(Fe) modified ZnS nanoparticles with enhanced sonocatalytic degradation of tetracycline antibiotic in water

“…It has shown excellent services in the sono/photocatalytic degradation of pollutants from water [16] . Mandal et al studied the sonocatalytic degradation of RhB using spherical ZnS as a semiconductor, and the measured degradation efficiency was 64% [17] . However, after forming a heterojunction with g-C 3 N 4 , the degradation efficiency improved by up to 92%, attributed to the improved charge separation.…”

Enhancement of graphitic carbon nitride (g‐C3N4) assisted photodegradation of Rhodamine B under visible light

“…[7][8][9] To date, various physical, biological, and chemical methods such as coagulation, reverse osmosis, flocculation, ultrafiltration, membrane separation, ozonation, ion exchange, advanced oxidation process, photophenton, and photocatalytic adsorption have been used to eliminate the colored pollutants. [10][11][12] The dye removal using biological methods is difficult and requires controlled conditions for, a long time due to their recalcitrant, complex structure, and the formation of strong intermediates. The dyes hinder the penetration and passing of sunlight through or into the water, therefore it damages and disturbs the development of living creatures and organisms, and also restricts the photosynthetic activity in water bodies.…”
