  Electrocatalysis V: electrocatalytic processes of chemical and electrical energy interconversion, AP.TEM

• Abstract

  The global objective of this proposal is the partial development of the several components of complete PEFCs, which in a subsequent stage should be integrated for the development of prototypes of operational plants. These objectives can be grouped in four main research lines: (1) Development, characterization and tests of catalysts for the reforming of alcohols and the purification of the…

• Abstract

  Electrochemical systems away from thermodynamic equilibrium have received great attention in the scientific community, mainly due to the ease with which instabilities emerge and also for simple manipulation of the control parameters. The study of electro-oxidation of small organic molecules is certainly one of the main issues in the research of electrocatalysis due to potential use in sys…

  Electro-oxidation of small organic molecules in alkaline medium: complex kinetics and electrocatalysis, BP.DR

• Abstract

  Nowadays, society is experiencing a number of environmental challenges such as pollution of the aquatic environment and atmosphere, compounded by the introduction of in natura wastewater and emission of gases from the burning of fossil fuels for power generation. Having been growing energy demand it is necessary to search alternative sources of energy, which can minimize the environmental…

• Abstract

  Anaerobic digestion has been considered as an attractive method to stabilize the organic matter from wastewater, since it recovers sustainable energy, such as H2 and other products of chemical interest. However, although the theoretical stoichiometric potential is 12 mol H2 mol-1, the energy recovery is low and the yield is thermodynamically limited to 4 mol H2 per mol of glucose. In this…

• Abstract

  Electrochemical studies in systems far from thermodynamic equilibrium have been highlighted in the scientific community, due mainly to the facility with which instabilities emerge and also for the simplicity in handling control parameters. The electro-oxidation study of small organic molecules is certainly a major issue in electrocatalysis research because of their potential us…

  Oscilatory kinetics and electrocatalysis during electro-oxidation of small organic molecules using single-crystal electrodes, BE.EP.DR

• Abstract

  The treatment of winery wastewater is one of the main environmental impacts in Spain and in Brazil because of the quantity and the qualitative aspects of the effluent: high biodegradable loads (up to 10 g L-1), low pH and recalcitrant pollutants. Several biological treatment technologies have been investigated for the winery wastewaters treatment; however microbial fuel cells (MFC) have …
