The development of non-noble electrocatalysts for low temperature fuel cells is essential for a broader use of hydrogen technologies. In this study, nitrogen doped carbon nanofibers are obtained without post-treatments; the effect of the carbonization temperature on the physicochemical properties of the carbon nanofibers was studied by X-Ray diffraction, Raman spectroscopy, Nitrogen adsorption and...
Both chlorophyll and the heme group of hemoglobin possess a central tetrapyrrolic structure formed by four pyrroles bonded to methine groups. It is important to stress that natural and synthetic tetrapyrroles involve interesting properties; and sometimes, in order to deploy them, it is convenient to trap these macrocycles within pore networks. Due to their nature, these molecules cannot be inserted...
