Rare-earth-containing perovskite nanomaterials: design, synthesis, properties and applications

“…Besides the electrocatalysis, the perovskite-type materials are also promising photocatalysts for water splitting. To promote the performance of the photocatalysts for HER, many strategies have been developed, such as interface engineering, [256][257][258] energy-band engineering, 254,259,260 and crystal structure modulation. 31,110,255 Similar to the electrocatalysts, surface structure and property of the perovskite materials are extremely important for photocatalysts.…”

Hyper oxygen incorporation in CeF3: a new intermediate-band photocatalyst for antibiotic degradation under visible/NIR light

“…18,19 All the time, the research of rare earth photocatalysts focus on CeO 2 and rare earth-based perovskites, some in connection with CeF 3 . [20][21][22] CeF 3 -based composite photocatalysts could convert visible light into ultraviolet light by efficient upconversion emissions of CeF 3 , enhancing the photocatalytic activity under visible light. 23,24 It has been hardly regarded as a feasible photocatalyst by itself and rarely used in NIR light photocatalysis due to its wide bandgap.…”

KTaO3 Wafers Doped with Sr or La Cations for Modeling Water-Splitting Photocatalysts: 3D Atom Imaging around Doping Cations

“…TaO 6 octahedra occupy the unit-cell corners. Doping KTaO 3 particles with Sr, La, , Hf, Zr, Ti, Si, Ga, In, Zn, Er, and Nb cations is known to increase the reaction yield in photocatalytic water splitting. Single-crystal wafers of this compound have been applied for the electrochemical , and photoelectrochemical oxidation of water.…”
