Fe‐Doped Ni3C Nanodots in N‐Doped Carbon Nanosheets for Efficient Hydrogen‐Evolution and Oxygen‐Evolution Electrocatalysis

“…When doped with Fe,t he Ni 3 Cb ased nanosheets exhibited outstanding electrocatalytic properties for both the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). Tremendous research efforts have been devoted to exploring inexpensive,e fficient, and durable non-precious electrocatalysts,i ncluding metals, [4] alloys, [5] metal oxides, [6] metal nitrides, [7] metal sulfides, [8] metal selenides, [9] metal carbides, [10] and metal hydroxides. An outstanding OER catalytic property is also achieved with alow overpotential of 275 mV and asmall Tafel slope of 62 mV dec À1 in KOHs olution.…”

“…[1] Theoxygen evolution reaction (OER) and hydrogen evolution reaction (HER) are two important half reactions involved in electrochemical water splitting. Tremendous research efforts have been devoted to exploring inexpensive,e fficient, and durable non-precious electrocatalysts,i ncluding metals, [4] alloys, [5] metal oxides, [6] metal nitrides, [7] metal sulfides, [8] metal selenides, [9] metal carbides, [10] and metal hydroxides. [3] Therefore,t he development of alternative non-noble metal catalysts with low-cost and earth abundance has become ag reat challenge for the HER or OER.…”

“…[2] Unfortunately,both OER and HER are kinetically sluggish, which require highly active electrocatalysts to expedite the process.N oble-metal-based catalysts,i ncluding Pt, RuO 2 ,and IrO 2 ,can efficiently reduce the energy barrier and thus increase the OER or HER efficiency,w hile their large-scale applications are still hindered by their high cost and earth scarcity. Tremendous research efforts have been devoted to exploring inexpensive,e fficient, and durable non-precious electrocatalysts,i ncluding metals, [4] alloys, [5] metal oxides, [6] metal nitrides, [7] metal sulfides, [8] metal selenides, [9] metal carbides, [10] and metal hydroxides.

[11] However, development of bifunctional electrocatalysts with effective both HER and OER properties is still abig challenge.Since the innovative report of tungsten carbide used as effective catalyst, transition-metal carbides (TMCs) have recently received great research interest owing to their many outstanding properties,i ncluding high electrical and thermal conductivities,h igh melting point, excellent mechanical strength and hardness,a nd also their chemical stabilities along with the resistance against corrosion.…”

Recent Progresses in Electrocatalysts for Water Electrolysis

“…Yin et al [250] also reported that the composition and morphology of alloy catalysts for HER are tuneable by using the galvanostatic method and is highly dependent on applied currents. In their obtained SEM images, as shown in Fig.…”
