WITHDRAWN: Synthesizing and Characterizing the Hybrid Pigment Fe 0.7 Cr1.3 O3 With High NIR Reflectance for Sustainable Energy Saving Applications

Abstract

Today, a growing number of the world population face a rise in the cost of living, especially an increase in energy costs. That is why Energy-saving has become a vital issue. In this regard, one of the remarkable ways to reduce energy consumption is using cool pigments; therefore, many kinds of research have been done to improve pigments' infrared reflection capability. In this paper, the role of particle morphology was investigated to boost the infrared reflection property of iron-chromium-based pigments. For this purpose, a series of inorganic pigments based on the Fe0.7Cr1.3O3 formula was prepared via a hydrothermal method. The particles' morphology was altered by using surfactants to improve the pigments' reflecting properties. The IR reflectance results proved that the flaky particles exhibit an enhanced IR reflection, which is significantly higher than in the spherical one. Furthermore, the results have revealed that silica coating leads to a meaningful improvement in the IR reflection property. It was found that the maximum near-infrared solar reflectance of the sample with 2.63% succinic acid surfactant and silica coating was 52.23% compared to that of Fe0.7Cr1.3O3, which was 25.36%.
