Gas Sensors Fabricated using Carbon Powder Derived from Dried Banana Peels Waste to detect Methanol, Ethanol, Acetone Vapors and Carbon Dioxide GasBy R.M.A.U. Weerasooriya, P.G.D.C.K. Karunarathna, P. Samarasekara
Abstract: Low cost and environmentally friendly activated carbon powder was synthesized using waste banana peels. Phosphoric acid was utilized as activation agent. Doctor blade method was employed to fabricate films of activated carbon on conductive or nonconductive glass substrates. Films were subsequently annealed at 70 0C for 30 minutes in air. According to XRD patterns, single phase of activated carbon was crystallized in thin film form. Carbon prepared from banana peels …
