example 1
[0037] Weigh 2 parts of Cu(CH3 COO) 2 , 4 parts of disodium ethylenediaminetetraacetic acid (EDTA), 1 part of KSCN, where Cu(CH 3 COO) 2 / EDTA=0.5, Cu(CH 3 COO) 2 / KCN=2.0: Dissolve the three substances weighed in 1000 parts of deionized aqueous solution, and then adjust the pH value to 2.1; the prepared solution is ready for use after 4 hours of static complexation and homogenization. Before deposition, ethanol, 0.1M NaOH and deionized water were used to 2 o 3 -SnO 2 Conductive glass (ITO) is cleaned and dried for use. A platinum sheet was used as an auxiliary electrode, a saturated Ag / AgCl electrode was used as a reference electrode, the temperature of the solution was lowered to 15°C, and the CuSCN film was obtained by depositing at -0.6V (relative to the saturated Ag / AgCl electrode) for 5 minutes. The deposited CuSCN film was rinsed with deionized water, dried at 90°C in vacuum and then tested. It was found that the electrodeposited CuSCN film had a thickness of ab...

[0039] Weigh 25 parts of CuSO 4 ·5H 2 O, 11 parts of oxalic acid, 1.6 parts of NaSCN, where CuSO 4 ·5H 2 O / .oxalic acid=2.3, CuSO 4 ·5H 2 O / NaSCN=15.5: Dissolve the weighed three substances in 1000 parts of deionized aqueous solution respectively, and adjust the pH value to 3; the prepared solution is ready for use after 24 hours of static complexation and homogenization. Before deposition, ethanol, 0.1M NaOH and deionized water were used to 2 o 3 -SnO 2 Conductive glass (ITO) is cleaned and dried for use. A platinum sheet was used as an auxiliary electrode, a saturated Ag / AgCl electrode was used as a reference electrode, the temperature of the solution was controlled at 35°C, and a CuSCN film was deposited at -0.6V (relative to the saturated Ag / AgCl electrode) for 10 minutes. The deposited CuSCN film was rinsed with deionized water, dried at 90°C in vacuum and then tested. It was found that the electrodeposited CuSCN film had a thickness of about 2 μm, a crystal grai...

[0041] Weigh 12.5 parts of CuSO respectively 4 ·5H 2 O, 10.5 parts of citric acid, 2.4 parts of KSCN, wherein CuSO 4 ·5H 2 O / oxalic acid = 1.2, CuSO 4 ·5H 2 O / KSCN=5.2: Dissolve the weighed three substances in 1000 parts of deionized aqueous solution respectively, and adjust the pH value to 4.6: The prepared solution is ready for use after 24 hours of static complexation and homogenization. Before deposition, ethanol, 0.1M NaOH and deionized water were used to 2 o 3 -SnO 2 Conductive glass (ITO) is cleaned and dried for use. A platinum sheet was used as an auxiliary electrode, a saturated Ag / AgCl electrode was used as a reference electrode, the temperature of the solution was controlled at 25°C, and a CuSCN film was deposited at -0.5V (relative to the saturated Ag / AgCl electrode) for 10 minutes. The deposited CuSCN film was rinsed with deionized water, dried at 90°C in vacuum and then tested. It is found that the electrodeposited CuSCN film has a thickness of about 1 ...
