The effect of Sr doping on the electronic structure and electromagnetic properties of LaCo_0.9Fe_0.1O₃ perovskites

Abstract

In this work, an electronic structure study of the La1-xSrxCo0.9Fe0.1O3 (LSCFO) perovskites is performed. The LSCFO perovskites were fabricated via a simple sol-gel method by modulating molar ratio of La3+/Sr2+....

Fe-Doped Metal Complex (LaCo0.9Fe0.1O3) and g-C3N4 Formed a Nanoheterojunction for the Photocatalytic Decomposition of Water

“…To cope with the disadvantages of the high cost and scarcity of noble metal catalysts, the development of low-cost and efficient transition-metal oxide catalysts (such as perovskite materials) has become a research hotspot. Perovskite generally refers to oxides having the chemical formula ABO 3 , which holds tremendous potential for applications such as sensors, magnetic reluctance devices, and catalysis. − At the same time, it is easy to form abundant oxygen vacancies, which is one of the most common defects in the list of semiconductor materials, especially in metal oxide semiconductors, and has an important effect on the performance of the list of semiconductor materials . For example, LaCoO 3 perovskite has attracted wide attention due to its excellent properties and its invention applications including photocatalytic water splitting hydrogen production catalysts, sensors, electromagnetic wave absorption, solid oxide fuel cells, and so forth. − However, its wide band gap, small specific surface area, and fast electron–hole complexation are unfavorable for hydrogen precipitation reactions.…”
