Platinum atoms at corners, edges, kink sites or dislocations are not more active than atoms on the crystallite faces for this reaction.
From the thermodynamic point of view, the atoms become more active and the motion of the atoms is more intensive, which means greater amplitude in its equilibrium position.
The CJ-Pd/Au catalyst showed a very high catalytic activity for glucose oxidation, and the top Au atoms decorating the Pd NCs were 20 30 times more active than the Au atoms of Au NCs with a size of 1.4-nm diameter.
The relatively higher positive charge on these H atoms marks more active bonds compared to the rest of the molecule.
Combining with the structure analysis and electrochemical measurement results, we concluded that the incorporation of 1T metal phase into its 2H matrix could increase the electro conductivity of the catalysts and yield more active sites due to the atom-rearrangement in the phase transformation progress.
Upon the activation of C H on (311), the stronger binding of ethylene on more active, under-coordinated surface lattice oxygen atoms of (311) forms a robust "deprotonated ethylene glycol -like intermediate on (311) with a rate-limitinglycol -like barrintermediateonmation of ethylene.
The nanoparticle, even though it is larger in size, appears to be more active compared to the smaller fluid atoms when placed in a temperature gradient.
Selective deposition of the noble metals at the less expensive Co nanoparticle (NP) surface by GR greatly enhanced the utilization efficiency of the more active Pt or Pt and Ir atoms for the selective catalysis to the ring-opening reaction of MCP, as justified by comparison with catalysts from conventional impregnation preparation.
When niobium was added to Zr Co Al metallic glasses, spatial structure of the atoms within short-range was changed, Fermi level is higher, atoms especially Zr d are more active, which makes it easier for the passivation film to produce and changes the structure of protective surface layers; thus, the corrosion resistance ability was better.
This is a clear indication that the nanoparticle is dramatically more active compared to the baseline fluid atom, which goes against the classical theories for the associated mean squared displacement of large particles compared to small micron-sized particles [39].
The electrons in outer atoms of Ag12Cu cluster have a more active characteristic than that of Ag13 cluster [50].
