Ammonia–borane (AB) is an excellent material for chemical storage of hydrogen. However, the practical utilization of AB for production of hydrogen is hindered by the need of expensive noble metal‐based catalysts. Here, we report CuxCo1−xO nanoparticles (NPs) facilely deposited on graphene oxide (GO) as a low‐cost and high‐performance catalyst for the hydrolysis of AB. This hybrid catalyst exhibits...
Graphenoxidfilme wurden als kostengünstige und flexible Nanogeneratoren hergestellt, die akustische Energie mit einem Wirkungsgrad von 12.1 % in Elektrizität umwandeln (siehe Bild). Der erzeugte Strom hing stark vom pH‐Wert der Suspensionen ab, die zur Herstellung der Graphenoxidfilme verwendet wurden.
