Synthesis of copper (I, II) oxides/hydrochar nanocomposites for the efficient sonocatalytic degradation of organic contaminants

Highly Porous Thin-Layer g-C3N4 Nanosheets with Enhanced Adsorption Capacity

“…1 There are various methods for removing organic pollutants from wastewater mainly based on oxidation and adsorption processes. 2,3 Oxidation processes, such as photocatalysis, microwave catalysis, Fenton, photo-Fenton, ultrasonication, and ozonation, transform organic and hazardous pollutants into harmless products. 3−5 However, most of these processes have disadvantages, such as byproduct formation and high operating costs.…”

“…In particular, water pollution with organic dyes from textile wastewaters is a serious environmental problem for the aquatic environment and human health . There are various methods for removing organic pollutants from wastewater mainly based on oxidation and adsorption processes. , Oxidation processes, such as photocatalysis, microwave catalysis, Fenton, photo-Fenton, ultrasonication, and ozonation, transform organic and hazardous pollutants into harmless products. − However, most of these processes have disadvantages, such as byproduct formation and high operating costs. , On the other hand, adsorption is recognized as a simple, efficient, and economically viable process without byproduct formation. − Many adsorbents such as activated carbon are fabricated to adsorb and separate dyes. − Commercially activated carbons is well-known as an ideal sorbent for the removal of colorful dyes. , However, the use of activation agents and the complex and time-consuming nature of activation processes limit their widespread application. , …”

Preparation of Ag3PO4/CoWO4 S-scheme heterojunction and study on sonocatalytic degradation of tetracycline

“…The collapse of transient bubble leads to the appearance of sonoluminescence (SL) and “hot spots”, which can generate high temperature and high pressure, exceeding 5000 K and 1000 atm, respectively [21] , [22] . Under such extreme conditions, water thermally decomposes to form free radicals, such as •OH, •H, •O 2 – , which are highly reactive and non-selective, attack organic molecules to produce CO 2 , H 2 O, and inorganic ions, or less toxic intermediates [23] , [24] . Since ultrasonic degradation combines sonic decomposition and photocatalysis, it is easier to increase the degradation of organic matter than AOPs alone [25] , and has the advantages of strong penetrating ability, simple operation, and no secondary pollution [26] , [27] .…”
