摘要
The global environmental and energy challenges necessitate the development of multifunctional materials that can address both pollutant removal and solar fuel production. In this groundbreaking study, we introduce the utilization of the Mo 2 AlB 2 MAB phase as a co‐catalyst in the SrTiO 3 /Mo 2 AlB 2 nanocomposite, marking the first instance of its application in photocatalytic approaches to combat environmental and energy crises. A nanocomposite of SrTiO 3 /Mo 2 AlB 2 was prepared by ultrasound‐assisted self‐assembly of SrTiO 3 nanocubes with crystal‐layered Mo 2 AlB 2 . The optimized catalyst denoted as STO@5‐MAB, was subjected to comprehensive characterization to evaluate its physiochemical properties. Remarkably, the STO@5‐MAB composite demonstrated exceptional performance in both photocatalytic carbendazim (CBZ) degradation, achieving an impressive degradation of 87.5% and CO 2 reduction to ethanol with a rate of 9.96 mmol g ‐1 h ‐1 under visible light illumination. This outstanding performance can be attributed to the composite’s 1) hydrophobicity 2) enhanced light absorption, and 3) the formation of a Schottky junction at the interface, facilitating efficient charge separation. In conclusion, the SrTiO 3 /Mo 2 AlB 2 nanocomposite demonstrates immense potential in addressing pressing environmental and energy challenges through photocatalytic carbendazim degradation and CO 2 reduction to ethanol. This study underscores the pivotal role of Mo 2 AlB 2 in developing efficient photocatalysts for environmental and energy applications. This article is protected by copyright. All rights reserved.
