Performance of metal-free carbonaceous catalysts in the removal of paracetamol by catalytic wet peroxide oxidation
(Corresponding) Santos Silva A., Henrique A., Steldinger H., Diaz de Tuesta J., Gläsel J., Correia Silva J., Etzold B., Gomes H.
Topic:
Advanced oxidation processes
The performance of metal-free carbonaceous catalysts was evaluated in the removal of paracetamol, chosen as model pharmaceutical micropollutant, by catalytic wet peroxide oxidation (CWPO). The carbon materials were prepared from pentaerythritol tetraacrylate and divinylbenzene copolymer with bis(2-...Read more
Valorisation of polyolefins into magnetic carbon nanotubes: application as catalysts in wet peroxide oxidation of paracetamol
Sanches L., (Corresponding) dos Santos Silva A., Fontana Roman F., Diaz de Tuesta Triviño J., Alves da Silva F., Gomes H.
Topic:
Advanced oxidation processes
This work deals with the application of magnetic carbon nanotubes (MCNTs) in the catalytic wet peroxide oxidation (CWPO) of paracetamol (PCM), a pharmaceutical compound selected as model contaminant of emerging concern (CEC). MCNTs were synthetized by catalytic chemical vapor deposition (CCVD) at...Read more
Carbon nanotubes synthesized from LDPE for application in wet peroxide oxidation of paracetamol
(Corresponding) Roman F., Marim Lopes J., Diaz de Tuesta J., Lenzi G., Tavares da Silva A., Faria J., Gomes H.
Topic:
Advanced oxidation processes
Carbon nanotubes (CNTs) were produced by chemical vapor deposition (CVD) considering low-density polyethylene (LDPE) as a carbon source and as an alternative to upcycle plastic solid waste. The CNTs were synthesized over bimetallic catalysts (Ni and Fe) supported on Al2O3 and purified with H2SO4 to...Read more
Selective denitrification of lipophilic pollutants from oily wastewater by peroxidation using Janus-structured amphiphilic carbon nanotubes as catalysts
Sanches F., Roman F., Silva A., Diaz de Tuesta J., Marin P., Machado B., Serp P., Silva A., (Corresponding) Gomes H.
Topic:
Advanced oxidation processes
Carbon nanotubes (CNTs) were tested as catalysts in the selective denitrification of 4-nitrophenol (4-NP) from oily wastewater by catalytic wet peroxide oxidation (CWPO). The CNTs were prepared by chemical vapor deposition, feeding sequentially ethylene (E) and/or acetonitrile (A) during different...Read more
Magnetic CoFe2O4@carbon yolk-shell nanoparticles as catalysts for the catalytic wet peroxide of paracetamol
Silva A., Costa Guari N., Diaz de Tuesta J., Eno Pottker W., Yassue Cordeiro P., (Corresponding) Gomes H.
Topic:
Advanced oxidation processes
This work focuses the use of carbon-coated magnetic cobalt ferrite nanoparticles as catalysts for catalytic wet peroxide oxidation (CWPO) of the emerging pollutant paracetamol. A magnetic core composed of CoFe2O4 is developed by a sol-gel method. The core is subsequently coated with a formaldehyde-...Read more
Degradation of textile dyes in water by gas-liquid NSP-DBD plasma
MEROPOULIS S., (Corresponding) AGGELOPOULOS C.
Topic:
Advanced oxidation processes
Textile dyes represent some of the most complicated environmental pollutants due to their variety and complex structure. Cold atmospheric plasma (CAP) is regarded as a highly competitive advanced oxidation process towards the removal of organic pollutants from wastewater. In this study, a gas-...Read more
TiO2/Fe2O3 based Composites for Solar-driven Photocatalytic Degradation of Amoxicillin
(Corresponding) dela Rosa F., Papac J., Kovačić M., (Corresponding) Kušić H., Božic A.
Topic:
Advanced oxidation processes
The occurrence of trace amounts of antibiotics in various bodies of water was directly linked to the development of antibiotic resistant pathogens. Recently, Amoxicillin (AMX) was added on the second EU “watch list” based on the proposed European Decision 2018/840/EU. Its presence in drinking water...Read more

Application of carbon-based catalysts derived from compost on catalytic wet peroxide oxidation of leachate waters from mechanical and biological treatment plant units for municipal solid waste
Batista G., (Corresponding) Roman F., Diaz de Tuesta J., Mambrini R., Gomes H.
Topic:
Advanced oxidation processes
This work aims at the valorization of compost from mechanical and biological treatment (MBT) units of municipal solid waste by their transformation into carbon-based catalysts for further application in the treatment of MBT leachate waters (chemical oxygen demand (COD) = 60.0 g L-1, total organic...Read more
Ultrasound-assisted Fenton-like degradation of methylene blue using electrospun nanofibrous membranes
Pervez M., Stylios G., Buonerba A., Hasan S., Cai Y., Zhao Y., Talukder M., Song H., Zarra T., (Corresponding) Naddeo V.
Topic:
Advanced oxidation processes
New materials supported by Green Chemistry have been receiving widespread attention because they are fulfilling the sustainable development goals (SDGs) agenda, for which clean water development is a top priority. Recently, electrospun nanofibers membranes are being frequently used to decontaminate...Read more
