摘要: Abstract Glassy carbon (GC) substrates were treated by the oxygen plasma over several periods of time. Scanning electron microscopy (SEM), transmission (TEM) and atomic force (AFM) study showed dramatic influence on morphology glassy carbon. The treatment leads to formation nanostructured surface, which consists well separated rod-like nanostructures oriented perpendicularly substrate surface. surface roughness was found increase with increasing By using magnetron co-sputtering platinum cerium oxide we can prepare layers continuously doped Pt atoms during growth. This technique combines etching growth deposit. high area catalyst makes this method promising for production thin film catalysts.
