“…On the other hand, tin (Sn) and sulfur (S) are earth‐abundant and their combination produces layered tin sulfide materials with outstanding electrical and optical properties 20 . Despite the availability of various sulfide polymorphisms, SnS 2 and SnS have been extensively researched in various fields including energy storage and conversion devices due to their nontoxicity, low cost, and impressive durability in acidic and alkaline environments., 9,2122‐24 However, due to their complicated phase‐controlled synthesis, they have rarely been reported in OER and UOR.…”

Summary In this work, SnS/SnS2 heterostructured film on a nickel foam (NF) through solution process was grown and employed directly as cathode and anode to the urea oxidation reaction (UOR). The as‐fabricated SnS/SnS2 film achieves high efficiency toward UOR with a lower potential of 1.38 V vs RHE to deliver 50 mA cm−2, which is approximately 200 mV less than the potential demanded for the oxygen evolution reaction (OER). More importantly, the electrolyzer consisting of two identical electrodes with the SnS/SnS2/NF ǁ SnS/SnS2/NF vs RHE assembly oxidizes urea at a lower potential of 1.36, 1.38, and 1.39 V vs RHE to deliver a current density of 10, 50, and 100 mAcm−2, respectively. The superior UOR performance of the SnS/SnS2‐based electrode is attributed to the combined merits of the SnS and SnS2 phases in the heterostructure, enhancing the catalytic active sites and providing the easy charge transport between the electrode and electrolyte.

Water splitting (or, water electrolysis) is considered as a promising approach to produce green hydrogen and relieve the ever‐increasing energy consumption as well as the accompanied environmental impact. Development of high‐efficiency, low‐cost practical water‐splitting systems demands elegant design and fabrication of catalyst‐loaded electrodes with both high activity and long‐life time. To this end, dimensional engineering strategies, which effectively tune the microstructure and activity of electrodes as well as the electrochemical kinetics, play an important role and have been extensively reported over the past years. Here, a type of most investigated electrode configurations is reviewed, combining particulate catalysts with 3D porous substrates (aerogels, metal foams, hydrogels, etc.), which offer special advantages in the field of water splitting. It is analyzed the design principles, structural and interfacial characteristics, and performance of particle‐3D substrate electrode systems including overpotential, cycle life, and the underlying mechanism toward improved catalytic properties. In particular, it is also categorized the catalysts as different dimensional particles, and show the importance of building hybrid composite electrodes by dimensional control and engineering. Finally, present challenges and possible research directions toward low‐cost high‐efficiency water splitting and hydrogen production is discussed.
