Two-dimensional (2D) black phosphorus (BP) has drawn tremendous attention in solar-light-driven catalytic processes for its intriguing chemical and physical properties. Benefiting from the highly anisotropic electronic structure induced by its puckered crystal geometry, 2D BP tends to have greater confinement with respect to traditional inorganic nanomaterials, thereby leading to robust many-body effects. Such Coulomb-interaction-mediated effects dominate the electronic and optical properties of 2D BP-based nanosystems, where exotic correlations between photoinduced species give rise to unique photoexcitation processes that are closely associated with the involved photocatalytic behavior. In this Perspective, we highlight the critical role of many-body effects in 2D BP-based photocatalysis and exemplify the relationships between the correlated photoinduced species-dominated photoexcitation processes and photocatalytic behavior involved therein. The relevant challenges and opportunities in pursuing efficient 2D BP-based solar energy utilization are also discussed.

二维黑磷中的光催化:多体效应的作用

二维(2D)黑磷(BP)由于其有趣的化学和物理特性而在太阳光驱动的催化过程中引起了极大的关注。得益于其起皱的晶体几何结构所诱导的高度各向异性的电子结构,相对于传统的无机纳米材料,2D BP往往具有更大的局限性,从而导致强大的多体效应。这种库仑相互作用介导的效应支配了基于2D BP的纳米系统的电子和光学特性,其中光诱导物种之间的奇异关联导致了独特的光激发过程,该过程与所涉及的光催化行为密切相关。从这个角度来看,我们强调了多体效应在基于2D BP的光催化中的关键作用,并举例说明了相关的光诱导物种主导的光激发过程与其中涉及的光催化行为之间的关系。还讨论了追求高效的基于2D BP的太阳能利用的相关挑战和机遇。
