Properties
-Created in small enough chunks
turns red, yellow, blue and other colors
-Becomes an excellent catalyst at 3-5 nm
-At nano scale is no longer a metal,
becomes a semiconductor
-1-D nanowires, 2-D nanofilms and 3-D supercrystals
Applications
A potential application is to aid firefighters,
who now wear protective masks containing
copper-manganese-oxide. That material's
effectiveness at getting rid of CO, however,
lasts only 15 minutes, while nanogold
protects for several hours. One such reaction is the conversion of carbon-monoxide (CO)
to carbon-dioxide (CO2). Nanogold catalyzes this at room
temperature and with 100-percent efficiency.
