Experimental and Theoretical Estimations of Atrazine’s Adsorption in Mangosteen-Peel-Derived Nanoporous Carbons (2024)
Matos, Juan; Amézquita-Marroquín, Claudia P.; Lozano, Johan D.; Zapata-Rivera, Jhon; Giraldo, Liliana; Poon, Po S.; Moreno-Piraján, Juan C. (Multidisciplinary Digital Publishing Institute (MDPI), 2023)Nanoporous carbons were prepared via chemical and physical activation from mangosteen-peel-derived chars. The removal of atrazine was studied due to the bifunctionality of the N groups. Pseudo-first-order, pseudo-second-order, ... -

Nanostructured KxNa1-xNbO3 hollow spheres as potential materials for the photocatalytic treatment of polluted water (2021)
Praxedes, Fabiano R.; Lima Nobre, Marcos Augusto; Poon, Po S.; Matos, Juan; Lanfredi, Silvania (Elsevier B.V., 2021-12-05)Potassium-sodium niobate-based hollows spheres were studied in the photocatalytic degradation of Basic Blue 41 dye in aqueous phase under UV irradiation. KxNa1-xNbO3 materials were prepared at 700 °C by the spray pyrolysis ... -

Photocatalytic performance of carbon-containing cumo-based catalysts under sunlight illumination (2022)
Muñoz-Flores, Paula; Poon, Po S.; Sepúlveda, Catherine Mauricio A.; Ania, Conchi; Matos, Juan (MDPI, 2022-01)Carbon-doped nanostructured CuMo-based photocatalysts were prepared by solvother-mal synthesis. Two thermal treatments—oxidative and inert atmosphere—were used for the synthesis of the catalysts, and the influence of ... -

The Cramer’s rule for the parametrization of phenol and its hydroxylated byproducts: UV spectroscopy vs. high performance liquid chromatography (2020)
Murillo-Acevedo, Yesid S.; Giraldo, Liliana S.; Poon, Po S.; Matos, Juan; Moreno-Piraján, Juan Carlos (Springer Science and Business Media Deutschland GmbH, 2020-10-02)A linear algebra theorem like Cramer’s rule was used for the analysis of a system of equations obtained from UV spectroscopy, and results were compared against those obtained from HPLC analysis. This parametrization allowed ... -

Upgrading of pine tannin biochars as electrochemical capacitor electrodes (2021)
Pérez-Rodríguez, S.; Pinto, Oscar; Izquierdo, Maria Teresa; Segura, Cristina; Poon, Po S.; Celzard, Alain; Matos, Juan; Fierro, Vanessa (Academic Press Inc., 2021-11)Biochar derived from the pyrolysis of pine tannin is a green and available by-product of oil manufacturing that presents interesting features after having been activated by KOH at 650 °C. Different weight ratios of KOH to ...
