BiOBr is used as a promising material in various photoelectrocatalytic reactions, but its application in hydrogen evolution reaction (HER) is not commonly reported, because the instability under photoelectrochemical environment has become a drawback for BiOBr as a photoelectrocatalyst for reduction reactions.1 To solve this problem, MoS2 is induced to form a van der Waals heterojunction to stabilize the crystal structure of BiOBr in HER.2 By DFT calculation, we state that the active sites in the heterojunction are on sulfur centers, which also combines BiOBr by van der Waals force. Moreover, different MoS2/BiOBr ratios can result in different structure tolerance of BiOBr: heterojunction with 1% MoS2 can increase the stability of BiOBr while 50% MoS2 even accelerate the reduction of BiOBr. By performing the in situ wide-angle X-ray diffraction (WAXD) on MoS2/BiOBr with 1% and 50% of MoS2, respectively, we monitored the phase transfer speed of BiOBr during the HER. Interestingly, when UV light is induced, there is less amount of BiOBr reduced under negative potential due by the photogenerated holes that could react with extra electrons from negative bias or photo energy and prevent BiOBr to be further reduced.3
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.
