Abstract
Pencemaran air akibat limbah industri tekstil yang mengandung pewarna AZO (gugus -N=N-) saat ini semakin meningkat dan membahayakan karena bersifat mutagenik dan karsinogenik. Salah satu cara untuk remediasi limbah pewarna AZO adalah dengan metode fotokatalisis. Material fotokatalis yang banyak digunakan ialah TiO2. Namun, rekombinasi yang terlalu besar perlu direduksi salah satunya dengan cara menambah alotrof karbon. Pada penelitian ini digunakan alotrof karbon (oksida grafena/Graphene oxide (GO), Multi-Walled Carbon Nanotubes (MWCNTs), dan fullerene C60) untuk meningkatkan performansi fotokatalis TiO2 dalam mendegradasi methyl orange sebagai representasi pewarna AZO. Komposit TiO2/alotrof karbon dipreparasi dengan metode hidrotermal pada temperatur 120°C selama 3 jam dengan variasi fraksi massa TiO2/alotrof karbon sebesar 0,99%, 2,91%, 4,76%, dan 9,09%. Struktur kristal, karakteristik permukaan, gugus fungsi ikatan, dan struktur pita energi dianalisis untuk mengetahui bagaimana kaitan dan kemampuan material dalam mendegradasi polutan organik. Aktivitas degradasi fotokatalisis TiO2/alotrof karbon dilakukan di reaktor tipe batch skala laboratorium dengan iradiasi UV-Vis selama 2 jam. Komposisi fotokatalis TiO2/alotrof karbon terbaik dalam mendegradasi methyl orange ialah ialah TiO2/MWCNTs 0.99%% sebesar 97%, TiO2/GO 9,09% sebesar 92%, dan TiO2/C60 0.99%.

Water pollution due to textile industry waste containing AZO dye (-N=N-) is currently increasing and can be dangerous because it is mutagenic and carcinogenic. One way to remediate AZO dye waste is by photocatalysis method. The photocatalyst material that is widely used is TiO2. However, higher recombination in TiO2 needs to be minimized, one of which is by adding carbon allotropes. In this study, allotropes of carbon including graphene oxide (GO), Multi-Walled Carbon Nanotubes (MWCNTs), and fullerenes C60 were used to improve the performance of TiO2 photocatalyst in degrading methyl orange as a representation of AZO dye. TiO2/carbon allotrope composites were prepared by hydrothermal method at 120°C for 3 hours with mass fraction variations of TiO2/carbon allotrophs of 0.99%, 2.91%, 4.76%, and 9.09%. Crystal structure, surface characteristics, functional groups, and energy band gap structures were analyzed to determine how the relationship and the ability of the material to degrade organic pollutants. The photocatalytic degradation activity of TiO2/carbon allotropes was carried out in a laboratory-scale batch reactor with UV-Vis irradiation for 2 hours. The best compositions of TiO2/carbon allotroph photocatalyst for degrading methyl orange were TiO2/MWCNTs 0.99% with 97%, TiO2/GO 9.09% with 92%, and TiO2/C60 0.99% with 78%.
