Pectins as Emulsifying Agent on the Preparation, Characterization, and Photocatalysis of Nano-LaCrO₃

Abstract

The use of environmentally friendly chemicals as the emulsifying agent in the preparation of the advanced materials is a focus and is very interesting to do. Although the focus is important, the advanced material that is made remains a top priority regarding characterization and its activity. One of the chemicals for making advanced and environmentally friendly materials such as LaCrO 3 perovskite is pectin functioning as the emulsifying agent. In general, perovskite compounds are materials with very wide applications such as fuel cells, electronic equipment, sensors, magnetic materials, photoluminescent materials, thermic catalysts, and photocatalysts. Furthermore, the use of various solvents to produce perovskite compounds with the aim of getting good applications has been done a lot such as water, alcohols, or other organic solvents, respectively, in mixing precursors directly, precipitation and coprecipitation, microwave, auto-combustion, sol-gel, and hydrothermal methods. In this chapter, preparation of LaCrO 3 using pectin as an emulsifying agent will be discussed in advance together with characterization and application of LaCrO 3 in the photocatalytic reaction of dyes and cellulose conversion.

Modified Sn-doped LaCrO3 nanostructures: focus on their characterization and applications as ethanol sensor at a lower temperature

“…On a basic level, FTIR examination in the material field is utilized to evaluate the useful functional groups that are the starching frequency of functional groups present in the synthesized material in relation to the documented compound [11]. The FTIR for undoped LaCrO 3 nanostructure shows strong absorption bands at 594.08 cm −1 for La-O stretch and 420.48 cm −1 for Cr-O stretch [20].…”

“…Perovskite structural material (ABO 3 ) can be prepared by mixing the lanthanide oxide and the oxides of the transition element. In the perovskite structure, the cations can fit into both the A and B sites [11]. These perovskites were blended using various methods such as hydrothermal [12][13][14], co-precipitation [15][16][17], sol-gel [18,19].…”
