摘要

在大气CO

浓度升高引发气候问题以及“双碳”目标推进的背景下，钙钛矿型PbTiO

虽具有光催化应用潜力，但纯相PbTiO

因带隙较宽、光生电子-空穴分离效率低而催化性能受限，稀土离子掺杂被视为提升其光催化性能的有效方法。采用水热法制备了纯相PbTiO

以及La、Sm、Pr、Dy和Tm离子掺杂的PbTiO

，通过XRD、SEM和UV-Vis DRS等方法表征了催化剂的物相、形貌及光电性能等，并评价了催化剂光催化CO

还原性能。结果表明，Pr

掺杂浓度为1%（物质的量分数）的PbTiO

呈尺寸为500~1100 nm的多边形块状，在CO

下300 W氙灯照射2 h后，该催化剂的CO、CH

产率分别达1.70 μmol/(g·h)、0.55 μmol/(g·h)，且呈现良好的稳定性。在60%N

/40%CO

混合气体下（其他条件不变），该催化剂的CO产量升至2.82 μmol/g，这是因为Pr

掺杂为PbTiO

提供了4f轨道，减小了带隙宽度，促进了光生电子-空穴对分离，显著提升了催化剂光催化CO

还原性能。

Abstract

Under the background of climate issues caused by the increase in CO

concentration in the atmosphere and the promotion of “dual carbon” goal

although perovskite-type PbTiO

has the potential for photocatalytic applications

its catalytic performa

nce is limited due to the wide band gap and low photogenerated electron-hole separation efficiency in pure-phase PbTiO

. Rare earth ions doping is regarded as an effective method to enhance its photocatalytic performance. Pure-phase PbTiO

and PbTiO

with La

Dy and Tm rare earth ions doping were prepared by the hydrothermal method. The phases

morphologies and photoelectric properties of catalysts were characterized by XRD

SEM and UV-Vis DRS

and the photocatalytic CO

reduction performances were evaluated. The results show that PbTiO

with 1% (mole fraction) Pr

doping presents a polygonal block shape with the size range of 500 nm to 1000 nm. After 2 hours of irradiation with a 300 W xenon lamp under CO

the CO and CH

yields of the catalyst reach 1.70 μmol/(g·h) and 0.55 μmol/(g·h)

respectively. Moreover

it exhibits good stability. Under 60%N

/40%CO

mixed gas (other conditions remaining unchanged)

the CO production of the catalyst increases to 2.82 μmol/g

because Pr

doping provides 4f orbitals for PbTiO

narrows the band gap

promotes photogenerated electron-hole separation

and significantly enhances the photocatalytic CO

reduction performance.
