Earlier studies have shown that the hybrid structures offer enhanced catalytic activity with more active sites [13].
In general, larger surface area often possesses a higher photocatalytic activity because of the more active sites on the surface.
Such structure with higher stacking number and shorter slab length is favorable for exposing more active sites, leading to higher catalytic activity.
This superiority of ZnO photocatalytic activity is because it has more active sites, higher reaction rates, and is more effective in generating hydrogen peroxide[18].
Secondly, the highly disordered structure resulted in more active sites, which were determinant to the electrocatalytic activity for OER.
High surface area obviously exhibits better catalytic activity, because a large specific surface area provides more active sites for adsorbing the reactants.
Thirdly, a highly disordered structure implied the presence of more active sites, which were key to the improvement in OER activity.
The promotion effect of cobalt on activity of the molybdenum catalyst was attributed to the formation of more active sites.
and formed more active sites on the catalyst surface.
Accordingly, the obtained material had more active sites for electrocatalysis.
Two of the more active sites I found were Avego and Zimride.
