Herein, a novel 3D petal‐like SnS₂ hierarchical structure is successfully prepared by a simple hydrothermal method. The as‐prepared samples are characterized by X‐ray diffraction and scanning electron microscopy. UV–vis spectra exhibit an absorption edge of ≈635 nm. Photoelectrochemical measurements demonstrate that the photocurrent density can be effectively increased from 0.04 to 1.10 μA cm⁻² with applied bias potential range from 0.1 to 1.0 V. Additionally, there is no significant decay of photocurrent density after 60 cycles. Its remarkable performance and excellent stability in photocatalytic hydrogen evolution can be attributed to the huge specific surface area, unique hierarchical structure of petals, and high charge separation efficiency. Based on these results, a conclusion can be drawn that the novel 3D petal‐like SnS₂ hierarchical structure will have a good development prospect in the future.
