Platinum nanoparticles "burrow" into a zeolite support and form new pores
01-Mar-2004 -
Catalytic converters in cars consist of tiny platinum particles that have been
deposited onto a porous ceramic support. At high temperatures, these particles
can sinter, meaning that they fuse together with the support material and
undergo chemical reactions. What is going on at the nanoscopic ...
