Ribeiro\, Associate Laboratory LSRE-LCM |December 17\, 2 020 – 14H30 | Online.\n\nStudent Seminar in Chemical Engineering (DEQ-FE UP)\n\nCarbon materials possess useful properties for several applications \, such as: (i) stability in acidic/basic media\; (ii) possibility to cont rol\, to some extent\, the porosity and the surface chemistry\; (iii) stru ctural stability at high temperatures\; and (iv) easy recovery of expensiv e metals (by burning away the support). Due to the high specific surface a rea\, activated carbons have been traditionally used as adsorbents or as s upports for metal catalysts\; whereas graphitic materials having high cond uctivity can be used as catalysts by themselves. Materials with very diffe rent properties can be found between amorphous activated carbons and graph itic materials.\n\nCarbon materials are commonly obtained by pyrolysis/the rmal annealing of a carbon source. However\, other synthesis techniques al low for a more accurate control of the properties of the resulting materia ls. These include sol-gel processes\, hydrothermal/solvothermal and self-a ssembly methodologies\, and chemical vapour deposition. Some of these tech niques also allow synthesizing hybrid magnetic carbon nanocomposites. Two general classes of these type of hybrid materials are usually considered: (i) carbon nanostructures decorated with magnetic nanoparticles\, in which the magnetic material is embedded or linked to the carbon structure\, wit hout being protected against the environment by a carbonaceous shell\; and (ii) carbon encapsulated magnetic nanoparticles\, which are core-shell st ructures with a carbonaceous shell and a core made of magnetic materials.\ n\nTextural\, morphological\, and surface chemistry properties can be char acterized by different techniques\, such as N2 physisorption\, microscopy\ , and temperature programmed desorption coupled to a mass spectrometry det ector (TPD-MS).\n\nCarbon-based materials are a subject of intense researc h\, with strong relevance in electronic\, electromagnetic\, electrochemica l\, environmental and biomedical applications.\n\n\n\nDr Rui S. Ribeiro is currently a Researcher at Associate Laboratory LSRE-LCM\, within the fram ework of project InSpeCt. He has been acquiring scientific expertise in th e preparation\, modification and characterization of nano- and macro-struc tured carbon-based materials for environmental applications.\nDr Ribeiro c ompleted the Integrated Master in Biological Engineering in 2009\, at Univ ersity of Minho. In 2011\, he joined LSRE-LCM as Research Fellow\; and in 2014\, he was awarded an Individual PhD Studentship by FCT – Fundação para a Ciência e a Tecnologia. Dr Ribeiro completed his PhD studies in th e field of Chemical and Biological Engineering in July 2018\, at FEUP.\n\n \n\n \;\n\n[Host: Joaquim Faria\, Associate Laboratory\, LSRE-LCM]\nIm age credits: Rui S.
