Tin sulphide (SnS 2 ) shows great potential in photo‐/electrochemical applications including hydrogen evolution due to its unique layered structure, intrinsic semiconducting nature and high optical absorption capacity. Hollow structured SnS 2 was synthesized by Xuexia He, Peng Hu and co‐workers (article no. 1900185 ) on FTO glass by template‐free solvothermal routine. The studies of morphology evolution and phase changing indicate that SnS 2 experienced the steps of tilted sheets aggregation, extensional growth with cross‐linking, formation of sphere wall starters, and then hollow structure completion. Specific surface energies difference between SnS 2 material and FTO substrate is believed to be the origin to trigger the conformation of the special hollow structure. – The cover article belongs to the Focus Section “TMD Synthesis”, a compilation of 7 articles in this issue, guest‐edited by Zheng Liu (cf. Preface, article no. 1900634 ).
