Upon the basis of our investigation, we attributed the better catalytic activity to abundant available surface active sites and synergistic effect, as well as the brushy hairs on the surface of PtAg NCs.
This high apparent activity can be attributed to the high intrinsic activity originated from the adjacent surface active sites of Mo2C and Mo2N as well as the large ECSA of PVA-Mo2C/Mo2N nanospheres with surface roughness.
With an increase in particle size of activated carbon adsorbent, the percentage removal of the fluoride ion has been decreased due to insufficient number of surface active sites that are available on activated carbon adsorbent to adsorb fluoride ions.
It has been commonly recognized that the surface active sites play a key role in the photocatalytic activity of semiconductor.
Due to the increased number of surface active sites available for degradation reactions, the octahedral Cu2O microcrystals presented higher photoelectrocatalytic activity compared to other shapes.
Previous studies also show that a larger surface area provides more surface active sites for the adsorption of the dye molecules resulting in efficient photocatalytic activity [28, 29, 30].
A higher H2O content lowered rate due to competition with carvone for surface active sites.
The oxidation of CNad− releases surface active sites for further glycine oxidation.
It shows a unique open structure allowing the full utilization of Au surface active sites.
This was explained through a competitive adsorption of HCN and COS reactants upon catalyst surface active sites.
For obtaining the advantages of high surface active sites, the electrocatalysts should combine both the morphological and component advantages.
