Materials and Methods. All reagents and solvents were purchased from commercial sources and were used without further purification. Fluorine-doped tin oxide (FTO, surface resistivity ~7 Ω/sq) coated glass plates, and copper(II) sulfate pentahydrate was purchased from Sigma-Aldrich. Ethylene diamine tetraacetic acid disodium salt dehydrate (≥ 99.0%) was purchased from Fluka Company. 1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane (>98.0%(GC)(T)) was purchased from TCI Company. SEM and EDX were carried out on Zeiss Supra 50 VP. High-resolution Vis spectra were recorded on a mini spectrophotometer (Pooyesh Tadbir Karaneh (Phystec)). Electrochemical experiments were performed using an EmStat 3+ potentiostat from PalmSens company (Netherlands).
CV studies were performed with a three-electrode setup, containing FTO, Ag/AgCl/KClsat, and a platinum foil used as working, reference, and counter electrodes, respectively. All potentials in this work were reported vs. Ag/AgCl/KClsat. The distance between two opposite sides of the FTO electrode was measured with a digital caliper MarCal 16ER model (Mahr, Germany). The temperature was measured with a Laserliner 082 (Germany).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
