Characteristics of Activated Carbon from Melinjo Shells Composed of TiO2 Nanoparticles

Abstract

The synthesis of activated carbon derived from biomass melinjo shells has been carried out by compiling it with TiO2 nanoparticles. TiO2 nanoparticles are used to improve the performance of adsorbents as degradation compounds. The main objective of this study was to determine the effect of TiO2 nanoparticles on the activated carbon composite. Activated carbon is first made by carbonizing biomass at 400°C for 15 minutes, then chemically activated with 65% KOH and physical activation at 500°C. TiO2 nanoparticles were dissolved in demin water and TEOS produced a mixture of sol and then composite with activated carbon 10 g, 20 g, 30 g, and 40g. The characteristics test which analyzes includes iodine number, XRD, SEM-EDX, and BET tests. Analysis of the largest iodine and surface area (BET) tests is at AC40 each 467.387 mg/g and 273.664 m2/g. The XRD showed that the activated carbon was amorphous while the composite produced a crystalline structure.
