Single-atom catalysts (SACs) are highly attractive for catalytic water splitting due to their ability to maximize the utilization efficiency of metal atoms. In this work, copper single atoms (CuSACs) were heterogeneously anchored onto the MWCNT/FeMOF (CuSACs@MC/FM) catalyst surface through atomic-level dispersion of Cu, effectively tuning the heterogeneity of the catalyst. The existence of CuSACs enhances the number of accessible active sites, enabling efficient hydrogen and oxygen evolution reaction (HER and OER) activity in alkaline media. The CuSACs@MC/FM hybrid catalysts exhibit low overpotentials, small Tafel slope value and excellent durability of up to 100 h for both OER and HER. Furthermore, we assembled a bifunctional CuSACs@MC/FM hybrid catalyst for overall water splitting and achieved a low cell voltage of 1.54 V at 10 mA/cm2 with excellent long-term stability. Additionally, CuSACs@MC/FM delivered a high mass activity of 70 A/g and ~84 % selectivity for H2O2 in the ORR. X-ray absorption spectroscopy revealed a dominant Cu–N coordination peak at ~1.4 Å, confirming the presence of atomically dispersed Cu–N sites that serve as the active centers and enhance the heterogeneous catalytic activity. This work demonstrates that interfacial site tuning and atomic-level modulation can significantly improve catalyst durability and efficiency, establishing CuSACs@MC/FM as a highly effective electrocatalyst to produce both H2 and H2O2.

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.
