the large SSA BET of the exposed {001} faces and the relatively high area of the
exposed {101} appear crucial in determining the remarkable activity of R and RE
nanocrystals. Conversely, the low SSA BET of exposed {001} faces and the high of
{101} faces agree with the worst activity of NBs. SP nanoparticles have intermediate behavior.

(SP); e and f nanobars (NB); g and h rhombic elongated (RE); B HRTEM images of the same
