The article "Rare earth element-modified MOF materials: synthesis and photocatalytic applications in environmental remediation" by Shu-Kun Le et al. reviews the synthesis and applications of rare earth element-modified metal-organic framework (MOF) materials in environmental remediation. The authors highlight the significant role of rare earth elements (REEs) in enhancing the photocatalytic activity of MOFs by broadening the absorption spectrum and trapping photoexcited carriers, thereby inhibiting electron-hole pair recombination. The review covers the synthesis methods, including the influence of chemical compounds, dimensions, and morphologies on photocatalytic performance. It also discusses the applications of REE-modified MOFs in removing antibiotics, reducing CO2, and producing hydrogen. The paper concludes by addressing the latest advancements, current challenges, and future prospects of these materials in environmental remediation and energy integration.The article "Rare earth element-modified MOF materials: synthesis and photocatalytic applications in environmental remediation" by Shu-Kun Le et al. reviews the synthesis and applications of rare earth element-modified metal-organic framework (MOF) materials in environmental remediation.
