Semiconductor facet junctions for photocatalytic CO₂ reduction

Abstract Photocatalytic carbon dioxide (CO 2 ) conversion has been recognized as one of the promising strategies for unraveling current environmental and energy problems attributed to the growing fossil fuel consumption of the human society because it can directly harness incident sunlight energy for converting waste CO 2 into valuable compounds. Increasing attention has been provoked to the semiconductor facet junction photocatalysts due to their unique feature in enhancing the photogenerated electron–hole pair utilization toward improving the photocatalytic CO 2 conversion performance. In the past decade, significant breakthroughs in the semiconductor facet junction photocatalysts for photocatalytic CO 2 conversion. In this review, we give a brief introduction on the development and the idea of the semiconductor facet junction photocatalysts. Then, the unique advantages of the semiconductor facet junction photocatalysts for photocatalytic CO 2 conversion are summarized. Subsequently, the recent development of semiconductor facet junction photocatalysts in photocatalytic CO 2 conversion is overviewed. We end this review by presenting the perspectives and challenges in this field for its future advancement toward practical applications. This review is expected to push forward the development of not only photocatalytic CO 2 conversion but also other energy and environmental photocatalytic applications.
