“…Gd 3+ has also been doped into semiconducting nanomaterials, such as TiO 2 and CdSe, to enhance the photocatalytic capacity. − Gd(OH) 3 nanorods can support Pd nanoparticles for hydrogenation or serve as main catalysts for Cr(VI) photoreduction in water. , When Gd 3+ or Gd 2 O 3 are doped into ZSM-5 zeolite catalysts, the coking effect, which blocks active sites and deactivates the catalysts, is effectively suppressed, making the composite catalysts coke-compatible and having a long service life. − Gd 2 O 3 and Gd(OH) 3 nanorods exhibit peroxidaselike enzyme activity .

Impurity doping is a promising method to impart new properties to various materials. Due to their unique optical, magnetic, and electrical properties, rare-earth ions have been extensively explored as active dopants in inorganic crystal lattices since the 18th century. Rare-earth doping can alter the crystallographic phase, morphology, and size, leading to tunable optical responses of doped nanomaterials. Moreover, rare-earth doping can control the ultimate electronic and catalytic performance of doped nanomaterials in a tunable and scalable manner, enabling significant improvements in energy harvesting and conversion. A better understanding of the critical role of rare-earth doping is a prerequisite for the development of an extensive repertoire of functional nanomaterials for practical applications. In this review, we highlight recent advances in rare-earth doping in inorganic nanomaterials and the associated applications in many fields. This review covers the key criteria for rare-earth doping, including basic electronic structures, lattice environments, and doping strategies, as well as fundamental design principles that enhance the electrical, optical, catalytic, and magnetic properties of the material. We also discuss future research directions and challenges in controlling rare-earth doping for new applications.

“…Rare earth element oxide ceramics, particularly pyrochlores, have been investigated for a wide range of applications in thermal barrier coatings, [1][2][3][4][5][6][7] catalytic activity, [7][8][9][10][11] solid oxide fuel cells, [12][13][14][15] and most extensively as host matrices for actinides in nuclear waste. [16][17][18][19] The pyrochlore family boasts a high number of compositions that have been successfully synthesized and studied for chemical durability, waste loading, radiation tolerance, and other related properties.…”
