Depleting reserves of fossil fuels and growing concerns with atmospheric CO2 levels necessitate the development of non-petroleum derived, renewable fuels and carbon-based building blocks for chemical industries. Solar and Biomass refineries have been proposed as potential replacements for the current petroleum paradigm, and one possible way to convert wate biomass to added value chemicals while also reducing water or CO2 to fuels is a direct photoelectrochemical approach. Identifying semiconductor material and co-catalyst combinations that can selectively drive key photo-oxidation reactions at high photocurrent densities remains a challenge in the field. In this presentation progress in developing semiconductors as photoanodes is discussed. Results with oxides like WO3, BiVO4, and SrTiO3 will be presented as well as with using 2D-TMD materials (MoS2) and organic semiconductor bulk heterojunctions. The oxidation activity toward key model reactions of the oxidation of biomass-derived 2,5-hydroxylmethylfurfural (HMF) into 2,5-Furandicarboxaldehyde (DFF) and 2,5-furandicarboxylicacid (FDCA), and the oxidation of glycerol will be examined and factors that determine selectivity will be presented. Aspects of solar light harvesting, material nanostructure, electrocatalysis kinetics, and charge-carrier separation/transport are discussed.
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.
