Hydrogen generated electrochemically by a water electrolysis cell in an ion exchange membrane configuration is regarded as a clean energy technology. However, the large fraction for the total electrical energy that is used for the anodic oxygen evolution reaction (OER) to produce low-price oxygen hinders the industrial-scale production of hydrogen. Electrocatalytic glycerol oxidation (GEOR) is a promising alternative to simultaneously produce value-added products and hydrogen. Platinum is currently one of the most active catalysts for GEOR due to its ability to break the C-H bond, but its performance suffers from various oxidation intermediates (CO-containing species) forming during GEOR and strongly adsorbing on Pt active sites. Pt-based bimetallic catalysts, therefore, have been increasingly studied to improve CO tolerance. In this work, Pt and Pt-Cu catalysts were proposed and synthesised by one-step potentiostatic electrodeposition onto a carbon fibre cloth (CFC) used as a gas diffusion layer for integrating in a membrane electrode assembly electrolysis cell. The surface morphology and composition of both depositions on carbon fibre were observed by scanning electron microscopy and energy dispersive spectroscopy. The electrocatalytic performance of both materials towards GEOR in 1 M NaOH was evaluated by cyclic voltammetry (with and without added glycerol) and chronoamperometry. It was observed that the electrocatalytic activity of the Pt-Cu/CFC at a content of ca. 37.5 wt% Pt was superior to that of Pt/CFC in terms of lower GEOR onset potential, higher mass activities and current density. The Pt-Cu/CFC also exhibited less CO(ads) poisoning than the Pt/CFC during long-term electrolysis. This improvement could be attributed to the presence of Cu atoms increasing the formation of oxygenated species which facilitate the oxidation of adsorbed intermediates on the Pt active sites.
nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
