I found a paper but seems like I lost my database and i could not find the literature.
It is about BDD electrodes being electrophobic/electrophilic when oxygen terminated which would then affect the heterogenous electron transfer of the BDD.
Hello Saiful,
By electrophilic or electrophobic, do you mean having faster or slower electron transfer kinetics? Based on what I have read, the kinetics are definitely affected by oxygen-termination.
In this review (http://pubs.rsc.org/en/content/articlelanding/2009/an/b910206j#!divAbstract), they mention that the oxygen-terminated version is hydrophilic while the as-made hydrogen-terminated BDD is hydrophobic, and that the electrochemistry is significantly affected by the surface termination. One of the references cited in this review might be able to answer your question. There are many other papers out there on the effect of surface termination on various electrochemical processes, such as:

http://jes.ecsdl.org/content/146/12/4551.abstract
http://www.sciencedirect.com/science/article/pii/S0013468606000314
Hopefully those answer your question. You could also check the references they cite or the references that cite these papers for more info.
Sincerely,
Kyle
I think the oxygen-terminated BDD are hydrophilic because hydrogen bonding with water molecules.
Hello Kyle, Juan,
I have read somewhere in the paper stated that the oxygen-terminated BDD would make it to become either electrophilic or electrophobic in which it would affect the heterogeneous electron transfer to be either faster of slower. One other paper used the terms nucleophilic and nulceophobic. But I can not find the articles in the database anymore and googling it does not help at all.
I will have a read at what you have sent me and see if there is something that I could get from the papers you have sent me. Thank you so much. But if you have encountered with more papers saying about these things. Please, I will be more than happy.
