“…Currently, Pt is considered as the most effective electrocatalyst for HER with nearly zero overpotential. [ 198,199 ] Unfortunately, its large‐scale application for electrocatalytic water splitting is suffered from the block of rare reserve and high cost. It is highly desired to develop earth‐abundant and cost‐effective catalyst with excellent activity as Pt substitute.…”

Hydrogen (H2) has been deemed as the most promising and valuable alternative to nonrenewable fossil fuels. Photocatalytic and electrocatalytic water splitting are considered to be the most efficient and environmentally friendly approaches for the sustainable H2 evolution reaction (HER). Graphene with a 3D framework has been utilized for the HER due to its unique structure and properties, including its hierarchical network, large specific surface area, diverse pore distribution, outstanding light absorption ability, and excellent electrical conductivity. The large specific surface area and hierarchically porous structure of 3D graphene can not only maximize the exposure of active sites but also promote electron transfer and gas product diffusion. In addition, the free‐standing 3D graphene monolith is easily recycled compared with powder phase support, which can prevent the loss of active catalysts. By making full use of the aforementioned merits, 3D graphene‐based composite materials show great promise as high‐performance catalysts toward photocatalytic and electrocatalytic HER. In this review, recent advances in fabricating 3D graphene‐based composite materials and their applications in both photocatalytic and electrocatalytic HER are summarized and discussed. Furthermore, the current challenges and future vision associated with the design, fabrication, and integration of 3D graphene‐based composite materials toward HER are put forward.

“…As of now the superlative materials which shows the highest activity are the noble metals like Pt, Ir, and Ru based materials but these lacks supremacy because of less abundance and more cost . Consequently, alternative catalysts which are effective in terms of cost and efficiency is required for both the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) . For more than decades, a range of transition metal based electrocatalysts have been synthesized which efficiently catalyze both HER and/or OER .…”

The development of noble metal free, robust catalyst is highly sought for commercialization of clean, renewable energy technology and to replace the fossil fuel‐based energy equipments. Herein, we report a highly efficient and stable ternary Nickel Iron oxide (NiFe2O4) electrocatalyst for bifunctional oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) in alkaline medium. The as‐synthesized NiFe2O4 has been confirmed by techniques like FESEM, HR‐TEM, powder X‐ray diffraction (XRD), and X‐ray photoelectron spectra analysis. NiFe2O4 demonstrate nanoparticle morphology with an average size of ∼10 nm. The synthesized NiFe2O4 electrocatalyst exhibit superior electrocatalytic efficiency for OER, and achieves a current density of 10 mA cm−2 at an overpotential of 290 mV, with smaller Tafel slope of 42 mV/dec. A stable performance of OER is obtained at 10 mA cm−2 for more than 8 h. The electrocatalytic activity of NiFe2O4 is comparable with benchmark electrocatalyst IrO2/C. Similarly, NiFe2O4 also shows superior HER activity in 1 M KOH. The enhanced bi‐functional activity of NiFe2O4 is thought to be the synergy between the multicomponent structure of NiFe2O4, high surface area, and stability leading to high electrical conductivity.

“…In recent years, there has been an ever-growing interest in the development of efficient, earth-abundant and inexpensive Pt-free electrocatalysts with long-term stability.O ft hese, molybdenum (Mo)-based compounds including Mo 2 C, [17][18][19] MoS 2 [20,21] and MoSe 2 [22,23] nanostructured materials have demonstrated remarkable HER performance [24,25] and have proven to be alternatives for Pt-based electrocatalysiso ft he HER. In particular, MoSe 2 represents ap romising non-noble-metalbased electrocatalyst and has one of the best-known HER performance in media.…”
