Abstract

Elektroda Lapis Tipis yang telah berhasil disintesis pada penelitian ini melalui elektrodeposisi menghasilkan  ZnO terdoping Sn pada kaca FTO yang diharapkan dapat berfungsi sebagai fotokatalis. Prekursor yang digunakan merupakan larutan elektrolit yang dapat menghasilkan ZnO sebagai semikondutor dan Sn sebagai doping logam yang dapat menurunkan band gap ZnO. Elektroda hasil sintesis dikarakterisasi menggunakan Difraksi Sinar-X (XRD) untuk mengetahui struktur dan ukuran kristal serta keberadaan senyawa secara kualitatif yang dibandingkan dengan literatur. Pada Aplikasi, •OH yang dihasilkan pada permukaan elektroda setelah penyinaran foton dapat mendegradasi zat warna RBB yang terdapat pada limbah tekstil secara fotokatalisis maupun fotoelekroktalisis. Penurunan konsentrasi serta absorbansi RBB dianalisis menggunakan spektrofotometer UV-Vis.
