Zn(OTf)2 (98%) and EtOH (99.9%, water content 40 ppm) were purchased from Sigma-Aldrich. Anhydrous MeOH (99.9%, water content 78 ppm) was purchased from Alfa Aesar. Zn foils with different thickness (10 μm [99.9%] and 100 μm [99.994%]) were purchased from Alfa Aesar. All the electrolyte solutions were formulated by dissolving Zn salts into solvents according to different concentrations in an Ar-filled glovebox. The cathode electrode material PANI was synthesized according to previous reports (37 ). Next, the PANI powders, Timical Super C45 (MTI) and PTFE (Sigma-Aldrich) ,were dispersed in anhydrous 2-propanol (99.5%; Sigma-Aldrich) with a mass ratio of 7:2:1. The slurry was then coated and calendared on a Ti mesh current collector and dried at room temperature overnight to remove 2-propanol. The loading of the PANI was ∼7 mg cm−2.
Anhydrous 2 propanol
Manufactured by Merck Group
Sourced in United States, United Kingdom
Anhydrous 2-propanol is a laboratory chemical that is used as a solvent and reagent in various scientific and industrial applications. It is a colorless, flammable liquid with a characteristic odor. The anhydrous form of 2-propanol, also known as isopropyl alcohol, contains no water and is commonly used in applications where water-free solvents are required.

The SAS was prepared from aluminum tri-sec butoxide (97 %; Sigma-Aldrich, USA), acetylacetone (99 %; Sigma-Aldrich), anhydrous 2-propanol (99.5 %; Sigma-Aldrich), methyltrimethoxysilane (95 %; Sigma-Aldrich), and 3-glycidylpropyltrimethoxysilane (GPTMS, 97 %; Sigma-Aldrich). First 20 g aluminum tri-sec butoxide, 5.4 g acetylacetone, and 5.4 g anhydrous 2-propanol were mixed and oil-bathed to form sol A. Then 30 g methyltrimethoxysilane, 17.3 g GPTMS, and 34 g anhydrous 2-propanol were mixed and oil-bathed to form sol B. Subsequently 21 g sol A was added to sol B, after which 37 g filtered water was added to form the SAS. The composite was refluxed at 80 °C for 12 h and then aged at room temperature for >24 h.

All the solutions were prepared with ultrapure water (AnalaR NORMAPUR ISO 3696 Grade 3, VWR Chemicals, Leicestershire, UK). The alcohols used were: HPLC-grade methanol with a purity of ≥99%, HPLC absolute ethanol without additive A15 o1 with a purity of ≥99.8%, 1-propanol anhydrous with a purity of ≥99.7%, 2-propanol anhydrous with a purity of ≥99.5% and 1-hexanol anhydrous with a purity of ≥99% (all from Sigma-Aldrich, Dorset, UK). The potassium chloride, disodium phosphate and PBS used all had a purity of ≥99% (all from Sigma-Aldrich, Dorset, UK). In a typical experiment, a liquid droplet (∼200 µL) of solution was deposited on a freshly cleaved HOPG or MoS 2 substrate (both from SPI supplies, West Chester, PA, USA) mounted on a stainless-steel disk. In all cases the substrates were baked at >120 °C for 20 minutes to remove any contaminants 61 before immediately depositing the droplet. The GrO was synthesised from graphite powder using a modified Hummers method, 62 presented in detail elsewhere. 63 To settle the flakes on the HOPG surface a droplet of 1 g L -1 GrO was de-
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.
