Sintesis Material Fotokatalis Strontium titanat (SrTiO3) dengan Metode Hidrotermal pada Variasi Suhu

Mohamad Thoif, Anton Prasetyo, Nur Aini

Abstract

SrTiO₃ disintesis dengan menggunakan metode hidrotermal dengan variasi 150, 175, 200, dan 225 ^oC selama 24 jam. Dari data XRD diperoleh hasil bahwa senyawa SrTiO3 berhasil disintesis pada suhu sintesis 150, 175 dan 200 ^oC akan tetapi masih ditemukan fasa pengotor berupa TiO₂. Morfologi partikel senyawa produk yang disintesis pada suhu 200 ^oC berbentuk kubus dan mempunyai ukuran yang paling besar dibandingkan sampel produk lainnya. Dari spectra DRS dapat diketahui bahwa nilai band gap senyawa SrTiO yang diperoleh pada rentang 3,14-3,20 eV.

Keywords

Strontium titanat; metode hidrotermal; morfologi partikel; energi celah
