Transition metal nitrides and oxynitrides were tested as electrochemical nitrogen reduction reaction (eNRR) catalysts for ammonia synthesis under ambient conditions. There have been several promising experiments on thin film electrodes in μ-reactor (Antec Scientific) (e.g.[1]). We have synthesized these catalysts as nanoparticles and incorporated to gas diffusion electrodes (GDE) to optimize the catalytic environment. One of the optimization steps needed is to understand the effect of pressure on the system. Gas pressure has been demonstrated to significantly affect the triple phase boundary and catalytic activity in CO2 reduction and is therefore anticipated also to have an effect in NRR [2], [3], [4], [5]. To increase the pressure in the flow cell and study the effect of the gas pressure on eNRR we have constructed a system for adjustable backpressure. To this end, a pressure-relief valve is used at the gas outlet of the flowcell. We will present studies focusing on the effect of the pressure increase on the catalytic behavior in a flow electrocell with gas diffusion electrodes for eNRR.

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.
