The need for finding new sources of renewable energy, clean and safe, puts the biomass as an energy source of great potential. Ethanol from lignocellulosic biomass, bagasse and straw, is a way to increase fuel production. Not only the question of availability of fossil fuels, but the environmental problems generated from their use as the greenhouse effect that contributes directly to global warming. The determination of carbohydrates in biomass has attracted great interest, since the accurate measurement of carbohydrate present in the samples is of utmost importance in assessing the efficiency and optimization of different processes of lignocellulosic ethanol production. Among the works developed in the analysis of carbohydrates by HPLC, using electrochemical detectors are distinguished by being sensitive, selective and present small limits of detection and a wide applicability. Given the great importance of the determination of carbohydrates in biomass together with the need to develop methods for fast, sensitive and selective determination, this project aims at the development of boron-doped diamond (BDD) and carbon nanotubos (CNT) chemically modified electrodes with metal nanoparticles (BDD/NP and CNT/NP) of NiO, CuO, FeOOH and AuO for use as electrochemical detectors in the determination of carbohydrates in lignocellulosic materials of sugar cane for HPLC with electrochemical detection (ED). The development of BDD/NP and CNT/NP will cover the construction, electrochemical, spectroscopic (XPS) and morphological (SEM-FEG) characterization, as well as the methodology for determining these compounds using the technique of HPLC-ED.
