HOPG (ZYA quality, GRAS/1.0 × 7.0 × 7.0) was purchased from ScanSens. Silicon nitride TEM supports (50 nm silicon nitride film on a 200 μm silicon frame with nine viewing windows, each 0.1 × 0.1 mm²) were purchased from Ted Pella. Sapphire (Al₂O₃) wafer (Z cut, 10 cm × 0.5 mm) was purchased from MTI. A TEM grid with 100-nm-thick c-out-of-plane-oriented gold film was purchased from Electron Microscopy Sciences. Single-crystal quartz (SiO₂) wafer (Z cut, 10.0 mm × 10.0 mm × 0.5 mm) was bought from MSE Supplies.

All reagents used in the experiments were of analytical grade and used without any further purification. Zinc nitrate hexahydrate (Zn(NO₃)₂ 6H₂O, Sigma-Aldrich, Steinheim, Germany) and sodium hydroxide (NaOH, Merck, Darmstadt, Germany) were used for the ZnO nanorods synthesis. Meanwhile, activated carbon (CAS 7440-44-0, M_w~12.01, Sigma-Aldrich Co., Burlington, MA, USA), polyvinyl alcohol (CAS 9002-89-5 Mowiol, 10–98/M_w~61,000, Sigma-Aldrich Co., Burlington, MA, USA), and glutaric acid (CAS 110-94-1, M_w~132.11, Merck, Burlington, MA, USA) were used to prepare the active material.
Commercial graphite sheets were used as substrate for the electrodes. The electrochemistry and desalination tests were conducted using sodium chloride 0.2 M (NaCl anhydrous, ≥99% purity, M_w~58.44.11, Sigma-Aldrich, Burlington, MA, USA).

With no further purification, analytical grade Zinc nitrate hexahydrate Zn(NO₃)₂·6H₂O (Sigma-Aldrich, MO, USA) is used. Cow dung is collected and dried under sunlight for 15 days is used as fuel. Discarded cooking oil is collected from several residences and pretreated before being used for transesterification.

Poly(vinyl pyrrolidone) (PVP, Mw = 1,300,000.00 g mol⁻¹), zinc nitrate hexahydrate (Zn(NO₃)₂·6H₂O), dimethylformamide (DMF) and poly(styrene sulfonate) (PSS, Mw= 200,000 g·mol⁻¹) solution 30 wt % in H₂O were all purchased from Sigma-Aldrich (St. Louis, MO, USA). The gas sensing experiments were performed using synthetic dry air, ammonia gas mixture (NH₃, 200 ppm in air), nitrogen dioxide (NO₂, 1000 ppm in N₂) and carbon monoxide (CO, 5% in Argon) obtained from Airgas (Radnor, PA, USA).

All chemicals utilized in this study were commercially purchased from suppliers and employed without further purification. 2-Methylimidazole (2-MIM, 99%), zinc nitrate hexahydrate (Zn(NO₃)₂·6H₂O, 99%), and methanol (MeOH, 99.99%) were purchased from Sigma Aldrich, South Korea. Prior to employing it as the current collector substrate, nickel foam (NF, 1.6 mm thickness) obtained from ALANTUM, South Korea, was carefully cleaned with HCl, ethanol, acetone, and deionized (DI) water.
