“…According to the relevant literature reports, we know that when certain lanthanide ions are doped in the catalysts, they can realize the up-conversion from visible to ultraviolet light of the substances [28], the extension of the response region [29], as well as the improvement of the separation efficiency of the photogenerated electron-hole pairs [30,31], which can improve the catalytic activity of the catalysts. Inspired by ultra-thin nanomaterials [32,33] and the MOFs of bimetallic porphyrins [34], we attempted to incorporate two lanthanide elements into porphyrin nanosheets to investigate their effects on photocatalytic performance.…”

The efficient synthesis of nanosheets containing two metal ions is currently a formidable challenge. Here, we attempted to dope lanthanide-based bimetals into porphyrin-based metal-organic skeleton materials (MOFs) by microwave-assisted heating. The results of the EDX, ICP, and XPS tests show that we have successfully synthesized porphyrin-based lanthanide bimetallic nanosheets (Tb-Eu-TCPP) using a household microwave oven. In addition, it is tested and experimentally evident that these nanosheets have a thinner thickness, a larger BET surface area, and higher photogenerated carrier separation efficiency than bulk porphyrin-based bimetallic materials, thus exhibiting enhanced photocatalytic activity and n-type semiconductor properties. Furthermore, the prepared Tb-Eu-TCPP nanomaterials are more efficient in generating single-linear state oxygen under visible light irradiation compared to pristine monometallic nanosheets due to the generation of bimetallic nodes. The significant increase in catalytic activity is attributed to the improved separation and transfer efficiency of photogenerated carriers. This study not only deepens our understanding of lanthanide bimetallic nanosheet materials but also introduces an innovative approach to improve the photocatalytic performance of MOFs.
