Abstract

Here, we successfully prepared STCu 0.08 -H nanofiber catalyst for photocatalytic reduction of CO 2 to methanol by electrospinning and hydrogen reduction. • STCu 0.08 -H nanofiber catalyst was successfully prepared by electrospinning combined with an in-situ dissolution strategy. • The doping of Cu 2+ regulated the energy band structure of perovskite and improved the light response-ability. • The exsolution of Cu + in the catalyst not only acted as the active center of the reaction but also promoted electron transfer. • The synergistic effect of Cu 2+ and Cu + promoted the photocatalytic reduction of CO 2 to methanol. Photocatalytic reduction of CO 2 to methanol over SrTiO 3 (ST) perovskite oxide is considered as a promising method to alleviate environment and energy problems at the same time. Meanwhile, the inducing of Cu plays an important role in photocatalytic activity and selectivity. Herein, a series of SrTi 1-x Cu x O 3 -H 2 (STCu x -H, x=0.04, 0.06, 0.08, and 0.1) nanofiber catalysts were prepared by electrospinning combined with in-situ dissolution strategy. Cu x O dissolved in situ on a one-dimensional nanofiber structure could realize more active sites exposed and convenient directional movement of electrons, simultaneously. The unique structure facilitates the enhancement of photocatalytic activity and the improvement of selectivity. The methanol yield of STCu 0.08 -H nanofiber catalyst upped to 5.38 ± 0.19 μmol·g -1 ·h -1 , which was twice that of ST. Moreover, the photocatalytic activity did not decrease significantly after four times of reuse. The characterization further demonstrated that STCu 0.08 -H had stronger light response ability and faster electron transfer ability than ST under the synergistic action of Cu 2+ and Cu + . STCu 0.08 -H had superior CO 2 adsorption, activation ability, and electronic reduction capability by DFT calculation. This study provided a new idea about the design of perovskite oxide nanofiber for photocatalytic CO 2 reduction.
