Photocatalysis is a highly efficient method for the conversion of solar energy and has shown great promise in mitigating the growing energy crisis and environmental pollution. However, achieving the desired solar energy conversion efficiency, which is directly limited by complex photoelectronic processes in the generation, transport, dissociation and recombination of charge carriers, is still a great challenge. These behaviors of charge carriers are considered to be dominated by electric effects. In this review, recent advances in the utilization of electric effects (e.g., piezoelectric effect, magnetoresistance effect, and excitonic effect) of charge carriers are discussed in relation to applications in photocatalytic processes. The mechanism of exciton dissociation in photocatalytic processes, the role of a built-in piezoelectric field, and negative magnetoresistance in promoting photoinduced charge transfer and separation are emphasized. This review provides insights into the potential challenges associated with leveraging the electric effects of carriers to reinforce photocatalysis.

电效应增强光催化的载流子行为


光催化是一种高效的太阳能转换方法，在缓解日益严重的能源危机和环境污染方面显示出巨大的前景。然而，实现所需的太阳能转换效率仍然是一个巨大的挑战，这直接受到电荷载流子的产生、传输、解离和复合等复杂光电过程的限制。载流子的这些行为被认为是由电效应主导的。在这篇综述中，讨论了载流子电效应（例如压电效应、磁阻效应和激子效应）在光催化过程中的应用的最新进展。强调了光催化过程中激子解离的机制、内置压电场的作用以及负磁阻在促进光致电荷转移和分离中的作用。这篇综述深入探讨了利用载流子的电效应来增强光催化作用的潜在挑战。
