Electrochemistry of monolayer protected nanoclusters

In this review, we evaluate the present state in the field of monolayer protected metal nanoclusters with regard to their synthesis, their optical and electrochemical properties and applications. Their quantum capacitance charging phenomenon and electroactive monolayer protected nanoclusters were especially stressed. Finally, we canvass some of the important remaining research opportunities in this field and present a brief outlook. We believe that progresses in this field would greatly promote the development of chemistry, bio-chemistry and material chemistry.
