Synthesis and characterization of srsno 3 using different synthesis methods

Research output: Contribution to journalArticle

Abstract

Perovskites are materials that have many potential applications, such as humidity sensors, transparent conductive oxides, photocatalysts and capacitors. Strontium stannate (SrSnO 3 ) is a perovskite semi-conductor material with a wide band gap. Several synthesis methods are commonly used to form SrSnO 3 , including solid-state reaction (SSR), sol-gel and hydrothermal. The SSR method requires high temperature calcination. On the other hand, sol-gel and hydrothermal methods merely need a lower calcination temperature to form perovskite materials. The sol-gel methods were done by adding a surfactant to Sr(NO 3 ) 2 and SnCl 2 solution in water before calcination. The autoclave approach was used in the hydrothermal method prior to calcination to form SrSnO 3 . The objective of this study was to determine the morphological and optical properties of SrSnO 3 synthesized by sol-gel, hydrothermal and SSR. The band gap was calculated via Kubelka-Munk relations and were found to be 4.05 eV (hydrothermal), 5.50 eV (sol-gel) and 3.95 eV (SSR). Sol-gel methods showed the widest band gap for SrSnO 3 . Optical results showed that there is a difference in terms of band gap for a perovskite synthesized by the different methods. Mass reduction analysis by TGA showed a sol-gel has mass loss of approximately 58% due to dehydration, which is more than for hydrothermally synthesized SrSnO 3 . This reduction is higher than for SrSnO 3 synthesized by hydrothermal method. It was observed that different synthesis methods impact the optical properties and morphology of SrSnO 3 powders.
