“…In the hunt for carbon-free energy, water electrolysis to produce hydrogen, which accounts for 4 % of global hydrogen production as opposed to more than 90 % driven by thermal energy, is a promising application of electrical energy. Electrochemical water splitting through reactions involving hydrogen evolution reaction (HER), [10][11][12][13][14][15][16][17] oxygen evolution reaction (OER), [18][19][20][21][22] and oxygen reduction reaction (ORR) [21,[23][24][25][26][27] using suitable catalysts which accelerate the hydrogen and oxygen evolution reactions. As an ideal catalyst for HER in-water splitting, platinum, and other noble metals are conventionally used.…”

A viable alternative to non‐renewable hydrocarbon fuels is hydrogen gas, created using a safe, environmentally friendly process like water splitting. An important role in water‐splitting applications is played by the development of two‐dimensional (2D) layered transition metal chalcogenides (TMDCs), transition metal carbides (MXenes), graphene‐derived 2D layered nanomaterials, phosphorene, and hexagonal boron nitride. Advanced synthesis methods and characterization instruments enabled an effective application for improved electrocatalytic water splitting and sustainable hydrogen production. Enhancing active sites, modifying the phase and electronic structure, adding conductive elements like transition metals, forming heterostructures, altering the defect state, etc., can improve the catalytic activity of 2D stacked hybrid monolayer nanomaterials. The majority of global research and development is focused on finding safer substitutes for petrochemical fuels, and this review summarizes recent advancements in the field of 2D monolayer nanomaterials in water splitting for industrial‐scale green hydrogen production and fuel cell applications.
