Die elektrochemische Umwandlung von Nitrat in Ammoniak ist ein wichtiger und nachhaltiger Ansatz zur Wiederherstellung des weltweit gestörten Stickstoffkreislaufs. rationale Entwicklung Katalysatoren für die Nitratreduktionsreaktion (NO3RR) auf der Grundlage eines detaillierten Verständnisses Reaktionsmechanismus großer Bedeutung. Wir berichten über einen Cu2O+Co3O4-Tandemkatalysator, NH3-Produ...

As phenol represents as the most typical persistent organic pollutants in wastewater, SO4•−-involved chemical oxidation techniques using monopersulfate (MPS) have been regarded a promising method to eliminate phenol. Since Co3O4 is benchmark heterogeneous catalyst for activating MPS, it highly critical investigate shape-varied catalysts with well-defined crystal planes MPS degrade Thus, aim of ...

Bifunctional electrocatalysts with both accelerated oxygen reduction reaction (ORR) and evolution (OER) enable high-power density electricity storage decentralized extraction of pure from air for usage in health care. Herein, a hydrothermal synthesis employing the anionic surfactant sodium dodecyl sulfate as structure-directing agent is developed to fabricate family crystalline mesoporous metal...

Porous Co3O4 nanonetworks (NNWs), converted from precursor CoOOH nanosheets, have been synthesized via a controllable chemical reaction route followed by calcination at 400 °C in air. The morphologies and microstructures of the precursor nanosheets and the final products were characterized by high-resolution transmission electron microscopy and X-ray diffraction, respectively. The growth mechan...

In this work, ZIF-8-derived Co3O4@ZnO microspheres were prepared by a liquid-phase concentration-controlled nucleation strategy. The results of the material characterization showed that obtained, and surface structure could be controlled with concentration ligand. Compared pure Co3O4 microspheres, operating temperature optimized increased 90 °C after gas-sensing test. response to 50 ppm acetone...

Thanks to their high energy density, light weight and long cycle life, rechargeable lithium ion batteries (LIBs) have become one of the dominant power sources for portable electronic devices. With the growing need for higher capacity and safety, numerous efforts have been made to develop alternative high-performance electrode materials for next-generation LIBs. As an example, the anode electrod...
