Inspired by biocatalysts in nature, artificial catalyst systems with behavior similar to or exceeding the activity of biocatalysts have been widely studied for different healthcare and environmental applications. In this work, a hybrid organic-inorganic approach is used to combine conducting polymer with inorganic materials for biocatalysis. Three different MoS2 nanosheets (MSNSs) were synthesized based on different methodologies. Methodology 1: ammonium tetra thiomolybdate (NH4)2MoS4 and hydrazine hydrate (N2H4·4H2O) were sonicated and transferred to an autoclave for the hydrothermal process. Methodology 2: MoS2 nanosheets were synthesized through a hydrothermal method using sodium molybdate Na2-MoO4.2H2O and L-cysteine. Methodology 3: MoS2 nanosheets were prepared through exfoliating of bulk MoS2 in N, N-Dimethylformamide (DMF) by sonication process. The morphology, and structural information of MSNSs were analyzed by TEM, SEM, XRD and Raman spectroscopy. Initial results show excellent catalytic performance of the MSNs with different concentrations of hydrogen peroxide ranging from 1µM to 10M. The catalytic behavior of the MSNSs were then compared with the performance of hydrogen peroxidase within the same range of concentration values.
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.
