The phrase "gold electrodes" refers to electric conductors made of the metal gold. They are used to transfer and measure electricity in scientific experiments or devices. Full definition
The metal - molecule interfaces are indicated; the golden balls represent gold electrodes. (sciencedaily.com)
It contains layers of gold electrodes just a few hundred nanometres thick, sandwiched between layers of polyimide plastic to form a «nanomembrane». (newscientist.com)
We used a combination of bulk electrochemical measurements and scanning electrochemical cell microscopy with submicrometer resolution to show that grain - boundary surface terminations in gold electrodes are more active than grain surfaces for electrochemical carbon dioxide (CO2) reduction to carbon monoxide (CO) but not for the competing hydrogen (H2) evolution reaction.
