CFCI Succeeds at Preparing Freestanding Mesoporous Metal!
 |
The preparation of this freestanding mesoporous metal was acheived via structure directing methodology under development in the Wiesner labs at CFCI (among other labs). Applying self-assembly of copolymer systems, CFCI researchers have successfully developed a route for and demonstrated synthesis of a freestanding mesoporous metal. The original article in Science was also reported by the Cornell Chronicle, C&E News, and by the National Science Foundation. The image at left shows models conveying the procedure. The diblock copolymer self-assembes with incorporated platinum nanoparticles (top). After pyrolysis under inert atmosphere, the mesoporous hexagonal morpholgy of the Pt-C composite is acheived (middle). Finally, etching the carbon leaves the hexagonally ordered, mesoporous platinum metal (bottom). |
