Unlocking the Potential of Moiré Superlattices in Electrocatalysis, Photocatalysis, and Piezo‐Photocatalysis

Moiré superlattices, a distinct class of 2D material structures, have showcased immense potential for catalytic applications in recent years. Their unique electronic structures and geometric configurations offer numerous active sites and optimized reaction pathways, thereby significantly enhancing catalytic performance. This review presents an overview of the latest progress in the application of moiré superlattice materials in electrocatalysis, photocatalysis, and piezo-photocatalysis. It is first introduced recent advances in the study of 2D materials with moiré superlattice structures in electrocatalysis, with a particular emphasis on the application of moiré metals in the hydrogen evolution reaction. Notably, recent breakthroughs demonstrate that moiré-patterned catalysts exhibit superior catalytic activity, surpassing commercial Pt/C catalysts in critical performance indicators. Subsequently, the distinct benefits of moiré superlattices in photocatalytic methane reforming are underscored. Moiré superlattice catalysts enable efficient methane conversion under significantly reduced energy consumption while maintaining a remarkable selectivity of up to 96%. Last but not least, this review highlights the exceptional performance of moiré superlattice structures in nitrate synthesis. The synergistic effects in this superlattice achieve an exceptional nitrate production rate of 15.44 mg g-1 h-1 under ultrasound and light irradiation. By exploring the catalytic mechanisms behind these avant-garde applications, this review aspires to deepen the understanding of moiré superlattices in catalytic science and technology, thereby facilitating further research and novel applications.
