Clean and sustainable hydrogen generation renders a magnificent prospect to fulfill the humans' dream of rebuilding energy supplying systems that work eternally and run without pollution. Water electrolysis driven by a renewable resource of energy, such as wind and solar, is a promising pathway to achieve this goal, which requires highly active and cost‐effective electrode materials to be developed. In this comprehensive review, we introduce the utilization of hierarchical nanostructures in electrocatalytic and photoelectrochemical applications. The unique emphasis is given on the synthetic strategies of attaining these hierarchical structures as well as to demonstrate their corresponding mechanisms for performance improvement. Rather than simply discussing all the methods that can be used in nanofabrication, we focus on extracting the rules for structural design based on highly accessible and reliable methods. Examples are given to illustrate the versatility of these methods in the synthesis and manipulation of hierarchical nanostructures, which are concentrated on nonprecious transition metals or their alloys/compounds. Through this study, we aim to establish valuable guidelines and provide further insights for researchers to facilitate their design of more efficient water splitting systems in the future.

“…The solvothermal method is by far the most reported. It involves heating of reactants in a particular solvent in a high-pressure system such as an autoclave [20][21][22][23]. Bin Li et al [25] reported the synthesis of NiSe 2 and NiTe nanorods via the solvothermal route at 180 1C for 15 h in ethylenediamine, whilst Han et al [24] reported the synthesis of various stoichiometries of nickel selenide under assorted conditions.…”

“…Nanomaterials such as Co 0.85 S, Ni 0.85 S (Liu et al, 2007), α-MnO 2 (Zhang and Mu, 2007) and NiO (Bai et al, 2007) with sea urchinlike shapes have been synthesized via chemical reduction process. As reported by Sekerka and co-authors, the solidification rate plays an important role in the morphology of the resulting particles and rapid solidification leads to the formation of dendrites with sharp tips Sekerka, 1963, 1964;Wang and Sekerka, 1996).…”

Metallic nickel particles with sea urchin-like shape have been prepared by rapidly chemical reduction of aqueous nickel sulfate solution with hydrazine. The phase structure and morphology of the particles have been investigated in view of the reduction temperature as well as the addition of sodium carbonate and surfactants. BET specific surface area measurement showed that the particles obtained at 89 • C had the roughest surfaces. The probable formation mechanism of the sea urchin-like particles was also discussed.
