Abstract Succeeding graphene a series of two‐dimensional materials (2D M) have been developed and applied in various fields. As an analog of silicene, 2D germanium (2D Ge) has garnered vast attention owing to its novel structures and prolific properties, demonstrating substantial promise in semiconductor, catalysis, devices, and other burgeoning fields. Specifically, 2D Ge is advantageous in providing a massive specific surface area, preferable transport properties, a tunable band gap structure, and confinement effects. Endowed with unique features, functionalized 2D Ge has become a competitive candidate for photocatalysis. In this review, we catalog various synthetic methods of 2D Ge, discuss its fundamental properties, and summarize recent applications. We also present a few perspectives to provide fresh insights into designing and exploring 2D germanium in future photocatalysis.
