The development of cheap and environmentally friendly fuels and chemicals whose production will be based on abundant and renewable resources appears as one of the main challenges in our society. Among different approaches, the direct use of sunlight for the valorisation of abundant resources, such as H2O, N2 or CO2, has been proposed as an appealing approach for the environmentally friendly and sustainable production of high added-value fuels and chemicals, such as H2, NH3, CH3OH or CH2CH2, among others, the so-called “solar fuels”. In this context, the photochemical solar fuels production is currently limited by the low light-to-chemical efficiency and the fact that in semiconductor-based photocatalysts light harvesting is usually restricted to the UV and visible blue light, and typically is affected by low charge separation efficiency and high recombination rates. In an alternative mechanism, photons from the visible and near infra-red (NIR) regions may interact with metal nanoparticles supported on thermally insulating materials by localized metal surface plasmon resonance (LSPR). In this pathway, much higher production rates and conversions have been reported since photon absorption promotes a localized heating in the active sites due to photon energy thermalization and generation of “hot carriers”, which influence the electronic structure of the species involved in the reaction.
In this presentation, it will be shown the design and fabrication of advanced multifunctional materials for the photothermal CO2 hydrogenation and NH3 production reactions in continuous flow. Moreover, mechanistic studies aimed to unravel which are the actual acfive sites and operational mode will be commented in detail. These research has the potential to advance the field and pave the way for the sustainalbe production of fuels and chemicals.
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.
