Light regulated ion transport across membranes is central to nature. Based on this, artificial nanofluidics with light driven ion transport behaviors has been developed for both fundamental study and practical applications. Here, we focus on recent progress in photothermal controlled ion transport systems and review the corresponding construction strategies in diverse photothermal nanofluidics with various dimensions and structures. We systematically emphasize the three underlying working principles including temperature gradient, water evaporation induced ion transport blockage, and evaporation gradient. On the basis of these fundamental research, photothermal regulated ion transport has been mainly introduced into ionic devices, desalination, and energy conversion. Furthermore, we provide some perspectives for the current challenges and future developments of this promising research field. We believe that this review could encourage further understanding and open the minds to develop new advances in this fertile research field.

跨膜的光调节离子传输是自然界的核心。在此基础上，已经开发了具有光驱动离子传输行为的人工纳米流体，用于基础研究和实际应用。在这里，我们重点介绍了光热控制离子传输系统的最新进展，并回顾了具有不同尺寸和结构的各种光热纳米流体的相应构建策略。我们系统地强调了三个基本工作原理，包括温度梯度、水蒸发引起的离子传输阻塞和蒸发梯度。在这些基础研究的基础上，光热调节离子传输主要被引入到离子器件、海水淡化和能量转换中。此外，我们为这个有前途的研究领域的当前挑战和未来发展提供了一些观点。我们相信，这篇综述可以鼓励进一步的理解，并开阔思路，在这个丰富的研究领域取得新的进展。
