Characterization Mass Ratio of TiO2: Coconut Shell Using FTIR analysis as a Super capacitor

The aim of this research is to determine the characteristics of the mass ratio of TiO2 to activated coconut shell. This research was carried out using a chemical deposition method which utilized H2SO4 as the reagent. Next is the activation of carbon which will later be used as supercapacitor material. Based on the objectives and methods carried out, the results obtained were that the mass ratio was 1:1, visible in the spectrum at wavelengths of 940 cm-1, 1037 cm-1, 1623 cm-1, and 2958 cm-1. Based on the spectrum at conditions 940-1037 cm-1, there are indications of the formation of C-C groups, in this condition carbonization is formed. At a mass ratio of 1:3 there is a wave shift starting at 884 cm-1 and the largest shift at a wave number of 2950 cm-1. In this comparison, O-H groups or carboxylic acids were still found. At a mass ratio of 1:5 the wave number shift starts at 884 cm-1, 1135 cm-1, 1635 cm-1 and 2362 cm-1. Based on the wave number 884-1135 cm-1, the functional group formed is the C-C bond, apart from that, the wavelength area of 1635 cm-1 shows the presence of the C=C bond
