Query on electrochemistry: Vectorial charge transfer meaning

[MarcoUscanga01]

TL;DR Summary

When talking about electrochemistry what is the difference between saying "electron transfer" and "vectorial electron transfer". It seems to me that "vectorial electron transfer" is just another fancy way of saying "electron transfer" but I am not quite sure if there is a kind of special meaning to it.

Hello guys!

When talking about electrochemistry what is the difference between saying "electron transfer" and "vectorial electron transfer". It seems to me that "vectorial electron transfer" is just another fancy way of saying "electron transfer" but I am not quite sure if there is a kind of special meaning to it.

My doubt comes from this part of a scientific article:

In addition, the doping process coupled to a nanostructuredmaterial has improved the interest of this material in photo-electrocatalysis, due to improvement in the active surface area(reaction/interaction can be facilitated between the catalyst andthe interacting media) and excellent electric properties, once thecharges carriers transfer is mainly governed by the quantum con-finement phenomenon [20]. For this purpose TiO2nanotube arrays(TiO2NTs) have shown high structural organization and excellentelectron percolation based on vectorial charge transfer between interfaces

An answer from a non-expert like myself: Did you read or skim ref [20]? "quantum confinement phenomenon" seems like the operative phrase just from context. Could be channeling along crystal axis? Just a wild guess.

I'm not an expert here neither, but as far as I can see from various sources, it seems to mean charge transfer occurring through a certain interface (molecule-to-molecule, particle-to-particle, grain-to-grain, wall-to-wall, etc.).

I am a bit knowledgeable in charge transfers due to the nature of my research, but I have never heard of the term"vectorial charge transfer". The term "vectorial charge transfer" does seem like a legitimate term since quick google scholar search shows that the first usage was in 1979, and has been used for quite some time.
