Electrocatalytic water splitting

Electrochemistry experiment observed at nanoscale to show splitting of water's hydrogen and oxygen atoms. Transformations or transmutations?

It is a well-known school experiment: When a voltage is applied between two electrodes inserted in water, molecular hydrogen and oxygen are produced.

We were able to show that during water splitting at nanometer rough spots i.e. a reactive centers, two different gold oxides are formed, which could represent important intermediates in the separation of the oxygen atom from the hydrogen atoms

Is this applicable to sea water with gold in it, or rivers with gold or other water features with other electrochemical catalysts in them?

a new method with which the initial steps electrocatalytic water splitting on a gold surface could be studied for the first time with a spatial resolution of less than 10 nm under operating conditions.

"We were able to show experimentally that surfaces with protrusions in the nanometer range split water in a more energy efficient way than flat surfaces" says Katrin Domke.

Or those burnt mounds built across streams?

If you have flows of energy, electrical potential differences between opposite banks or shoresshores? Telluric currents, electromagnetic plasma discharge events etc.

Or the atmospheric dusty plasmas? Deluge of chemical elements?

Is this standard atom model transformation or variation of low energy non nuclear transmutation of elements or atomic compounds?
