Greenhouse gas Carbon dioxide (CO₂) emission has attracted world‐wide attention and urgent actions are needed to reduce the impact of CO₂ on the climate change challenge. Photocatalytic CO₂ reduction reaction (CO₂RR) is regarded as a promising way for utilizing CO₂ as a feedstock to produce value‐added chemicals driven by sustainable solar energy. Efficient photocatalysts are crucially important for achieving high performance CO₂RR. Taking the advantages of hollow structure in light harvesting, large surface area and ability to enrich the local CO₂ concentration, the hollow photocatalysts have demonstrated their great potential for photocatalytic CO₂RR. Herein, we provide a concise overview on the mechanism, state‐of‐the‐art advances and future perspective in hollow structured photocatalysts for photocatalytic CO₂RR.
