25 mM SnCl2·2H2O , 150 mM nitric acid balanced by redistilled water. Oxygen is blown into the mixed solutions at a bath temperature of 85 °C for 1 h to oxidize the stannous ions into the stannic ions. then electrochemical deposition must be done in this temperature. -0.6V for 10 min. in this method SnOH is possible to attach.

20 mM tin chloride, 0.1 M sodium nitrate

and 75 mM nitric acid in pure

water. SnO2 was deposited in the templates using a fixed

potential of −0.4 V (versus Ag/AgCl) with varying deposition

times.

Can you give me more specific details what do you especially want to know?

according to these materials Graphene oxide can be reduced in 6mM KOH by using Cyclic Voltammetry
