摘要

近年来,稀土金属铁氧体异质结因其优异的光催化性能和在水处理和能量转换方面的潜在应用而受到广泛关注。稀土金属铁氧体加入到异质结光催化体系中,提高了光吸收、电荷分离和光催化效率。本文综述了几种常见的稀土金属铁氧体LaFeO3、GdFeO3、SmFeO3、PrFeO3和CeFeO3及其光催化剂性能。详细讨论了光催化污染物去除和能量转换机理,并探讨了文献报道的基于稀土金属铁氧体的各种异质结及其合成路线。综述了近年来稀土铁氧体异质结在污染物去除和能量转换方面的主要研究成果和进展。尽管在提高光催化效率和稳定性方面取得了显著进展,但仍存在一些挑战。目前的研究重点是材料合成和性能的改进,但诸如高生产成本、可扩展合成和有限的长期稳定性等问题仍然存在。未来的方向应该集中在探索未知的应用,新的材料组合和加强这些异质结的实际实施,以充分发挥其在环境和能源技术中的潜力。

Recent advances in rare earth metal ferrites-based heterojunctions for photocatalytic water treatment, hydrogen production and CO2 conversion

Recent advances in rare earth metal ferrites-based heterojunctions for photocatalytic water treatment, hydrogen production and CO2 conversion
Rare earth metal ferrites-based heterojunctions have garnered significant attention in recent years due to their exceptional photocatalytic properties and potential applications in water treatment and energy conversion. The incorporation of rare earth metal ferrites into heterojunction photocatalytic systems enhances light absorption, charge separation and photocatalytic efficiency. This review comprehensively discusses some common types of rare earth metal ferrites such as LaFeO3, GdFeO3, SmFeO3, PrFeO3 and CeFeO3 and their properties as photocatalysts. The photocatalytic pollutants removal and energy conversion mechanisms are discussed in detail and various types of heterojunctions reported in literature based on rare earth metal ferrites and their synthetic routes are also explored. The recent key findings and advances in the heterojunctions based on these rare earth metal ferrites for the pollutants removal and energy conversion applications are summarized. Despite notable progress in enhancing photocatalytic efficiency and stability, several challenges remain. Current research highlights improvements in material synthesis and performance, but issues such as high production costs, scalable synthesis and limited long-term stability persist. Future directions should focus on exploring uncharted applications, novel material combinations and enhancing the practical implementation of these heterojunctions to fully exploit their potential in environmental and energy technologies.

期刊介绍: The Journal of Rare Earths reports studies on the 17 rare earth elements. It is a unique English-language learned journal that publishes works on various aspects of basic theory and applied science in the field of rare earths (RE). The journal accepts original high-quality original research papers and review articles with inventive content, and complete experimental data. It represents high academic standards and new progress in the RE field. Due to the advantage of abundant RE resources of China, the research on RE develops very actively, and papers on the latest progress in this field emerge every year. It is not only an important resource in which technicians publish and obtain their latest research results on RE, but also an important way of reflecting the updated progress in RE research field. The Journal of Rare Earths covers all research and application of RE rare earths including spectroscopy, luminescence and phosphors, rare earth catalysis, magnetism and magnetic materials, advanced rare earth materials, RE chemistry & hydrometallurgy, RE metallography & pyrometallurgy, RE new materials, RE solid state physics & solid state chemistry, rare earth applications, RE analysis & test, RE geology & ore dressing, etc.
