Hi Anju, the short answer is "no". Consider the purpose of the reference electrode. What is required is that any change in the potential applied to the cell should only be expressed across the solution-working electrode interface. This requires the potential across the reference electrode-solution interface to be fixed, typically by exploiting the Nernst equation and solubility equilibria for e.g. calomel or silver chloride. More specifically, electrodeposition is a bit of a black art. Getting the desired form of the electrodeposit requires all kinds of decisions about the experimental conditions. If you are intending to use constant current deposition, then a reference electrode may still be necessary to be confident that the desired working electrode reaction is still dominating. The form of deposit is strongly affected by current density and pulsed deposition is often used to control the number of nucleation sites. Different conditions are then required to get the desired growth.

Generally standard hydrogen electrode and calomile (Hg2Cl2) are mainly used as reference electrodes because they don't affected by medium during reaction but if you mean as axillary electrodes you can use however platinum is recommended instead of gold.
Hi Anju,
Only the gold plate cannot be used as a reference electrode. A slightly soluble gold salt is required by analogy with silver chloride or calomel electrodes. In addition, you need to know for sure that this galvanic half-element has a stable potential, and I have not met such information.
