赤铁矿纳米材料的合成方法及应用

Synthesis and Application of Hematite Nanomaterials

赤铁矿因其热力学稳定、存在范围广、环境无害、催化特性突出而在各种氧化铁和(氧)氢氧化物中备受关注。赤铁矿纳米晶体在自然界中含量丰富,它们对元素和环境污染物的命运和转化的影响是深远的,在生物医学、太阳能电池、锂离子电池、环境修复等领域被广泛研究。因此,本文重点介绍了当前不同晶面和不同形态赤铁矿的合成方法与环境应用的最新进展。

Hematite has attracted much attention in various iron oxides and hydroxides because of its thermodynamic stability, wide range of existence, environmental protection, and outstanding catalytic properties. Hematite nanocrystals are abundant in nature, and their influence on the fate and trans- formation of elements and environmental pollutants is profound, and they have been widely studied in biomedicine, solar cells, lithium-ion batteries, environmental remediation, and other fields. In this paper, the synthesis methods and environmental applications of hematite with different crystal faces and morphologies are introduced.
