Abstract Solar energy can be utilized in photocatalysis technology to realize light‐driven hydrogen peroxide (H 2 O 2 ) production, a green chemical synthesis route. Designing high‐performance photocatalysts is critical to achieving practical solar H 2 O 2 production. During the past decade, significant research progress is made in photocatalytic materials for H 2 O 2 production. Particularly 2D materials‐based photocatalysts stand out due to their unique physical and chemical properties. This review highlights the intricate relationship between 2D material innovation and photochemical H 2 O 2 production. It starts with the fundamental principles of photochemical H 2 O 2 generation, focusing on crucial steps such as photon absorption, carrier dynamics, surface reactions, and the challenges that 2D materials can solve at each step. Then, various 2D materials‐based photocatalysts for solar H 2 O 2 production are introduced in detail. Engineering strategies to optimize the photocatalytic performance are discussed afterward. Finally, the challenges and future opportunities for designing 2D materials‐based photocatalysts for solar H 2 O 2 production are outlined. This review is expected to inspire the engineering of 2D materials‐based photocatalysts for the green synthesis of H 2 O 2 and the conversion of solar energy to other chemicals.
