Developing high-performance nonprecious electrocatalysts for oxygen evolution reaction (OER) is of great importance, but it remains a challenge. In this paper, we synthesize a porous monolithic catalytic electrode, which is transition metal nitride, Ni3FeN, constructed on a 3D network-like support of the strutted graphene foam (Ni3FeN/SG). The obtained Ni3FeN/SG electrode shows the excellent catalytic activity and the durability for OER in alkaline solution, owing to iron incorporation, high electrical conductivity and 3D network-like structure of strutted graphene. It requires small overpotential (226 mV) to actuate 10 mA cm−2, superior to most recently developed catalysts and commercial RuO2. The fabrication strategy provides a substantial way to expand 3D porous monolithic electrodes for various electrocatalytic applications.

Water Dispersibility

We present an efficient process for producing water dispersible graphene sheets from unassembled graphene–polyaniline nanohybrids. The result of atomic force microscopy reveals that over 80% of thus-prepared graphitic sheets are single layers with typical thickness of approximately 0.8 nm. The proportion of modifying molecules in the product is found to be as low as 3.0 wt.%, as determined by elemental analysis. Along with its fascinating water dispersibility and remarkably high electrical conductivity, such material is anticipated to be very promising for use in graphene-based nanoelectronics and high-performance composites.

Long Lifetime

Electrical contacts are usually plated in order to prevent corrosion. Platings of detachable electrical contacts experience wear because of the motion between contacts. Once the protecting platings have been worn out, electrical contacts will fail rapidly due to corrosion or fretting corrosion. Therefore the wear resistance of the platings is a very important parameter for the long lifetime of electrical contacts. Many measures which improve the wear resistance can diminish the conductivity of the platings. Due to the fact that platings of electrical contacts must have both a high wear resistance and a high electrical conductivity, the manufacturing of high performance platings of electrical contacts poses a great challenge. Our study shows firstly the correlation between the wear resistance of platings and lifetime of electrical contacts and then the measures, which improve the wear resistance without impairing the electrical performance of the contacts.
