The low utilization and stability of noble-metal catalysts is always a big barrier to commercialize proton exchange membrane (PEM) fuel cells. Here we report a positive progress on stabilizing the catalyst by modulating 2D graphene as an advanced support of Pt nanoparticles, where the interlayer of graphene is near perfectly intercalated by nano-B4C ceramics. The strong restriction effect of nano-ceramics...
Multi-walled carbon nanotube (MWNT) composites were fabricated using the screw extrusion and injection technique. The polymer-wrapped MWNTs were dispersed in fumed silicon dioxide with the help of ultrasonic stirring, and then further dispersed in a high density polyethylene (HDPE) matrix by a twin-screw extruder. It was found that there was a critical MWNT concentration around 1.0 wt% where a fine...
