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

Plastic to microplastic in the United Arab Emirates – plastic bottle caps in a hot, arid environment

Selem B., Alkarbi A., Alhosani A., Ahmad F., Elemam M., Iftikhar S., Mourad A., (Corresponding) Thiemann T.
Topic: 
Soil and groundwater contamination and remediation
The degradation of plastic bottle tops as a common contributor to plastic waste in the environment was assessed under the hot, arid conditions of the hinterland of the United Arab Emirates. 500 bottles tops were collected from 5 different locations in the Al Ain area and their surface oxidation...Read more
