“…In a work with FeN x sites supported on graphite, a negative correlation between the number of graphitic layers and fuel cell performance was observed, implying that FeN x sites within the graphitic plane also highly contributes to the catalytic activity . Similar to the configurations at the edges, Pt atoms anchored on highly curved supports exhibited excellent HER activity . The high curvature of the support could lead to the accumulation of electrons around the Pt regions, which induces a local electric field for proton (H + ) enrichment, thus accelerating the catalytic kinetics (Figure b).…”

“…Engineering the local atomic environment of single Pt atoms for the HER has been reported by several works, strategies include tuning the coordination atoms and changing the location of Pt atoms . The graphdiyne supported Pt atoms with four external Cl ligands (Pt‐GDY1) were synthesized by impregnating the as‐prepared graphdiyne in K 2 PtCl 4 aqueous solution at 0 °C for 8 h .…”

“…Although Pt‐GDY1 has a more negative Δ G H* than commercial Pt/C, it still exhibited a higher mass activity due to its superior Pt utilization. Liu et al reported the synthesis of Pt SACs on highly curved carbon nanospheres (Pt 1 /OLC) . The surface‐oxidized detonation nanodiamonds were first treated by thermal annealing at 1500 °C to to form onion‐like carbon (OLC) nanospheres with a suitable type and distribution density of oxygen species for anchoring Pt atoms.…”

Carbon‐based heteroatom‐coordinated single‐atom catalysts (SACs) are promising candidates for energy‐related electrocatalysts because of their low‐cost, tunable catalytic activity/selectivity, and relatively homogeneous morphologies. Unique interactions between single metal sites and their surrounding coordination environments play a significant role in modulating the electronic structure of the metal centers, leading to unusual scaling relationships, new reaction mechanisms, and improved catalytic performance. This review summarizes recent advancements in engineering of the local coordination environment of SACs for improved electrocatalytic performance for several crucial energy‐convention electrochemical reactions: oxygen reduction reaction, hydrogen evolution reaction, oxygen evolution reaction, CO2 reduction reaction, and nitrogen reduction reaction. Various engineering strategies including heteroatom‐doping, changing the location of SACs on their support, introducing external ligands, and constructing dual metal sites are comprehensively discussed. The controllable synthetic methods and the activity enhancement mechanism of state‐of‐the‐art SACs are also highlighted. Recent achievements in the electronic modification of SACs will provide an understanding of the structure–activity relationship for the rational design of advanced electrocatalysts.

“…HER is the counter reaction of OER in water electrolysis. Even though HER requires relatively low overpotential to obtain a decent current density compared to OER, it however requires precious metal‐based catalysts such as Pt . For Earth‐abundant materials, the overpotential of HER is usually significantly higher.…”

Global‐scale application of water splitting technology for hydrogen fuel production and storage of intermittent renewable energy sources such as solar and wind has called for the development of oxygen evolution catalysts and hydrogen evolution catalysts that are inexpensive, efficient, robust, and can withstand frequent power interruptions and shutdowns. Current water electrolyzers must operate with a protective current in stand‐by/idle modes to avoid a substantial catalyst degradation. Here, we show a hierarchically structured porous ternary composite catalyst of nickel, cobalt and iron (NiCoFe) hydroxides prepared via electrodeposition on three‐dimensional (3D) nickel foam (NF) substrates as reversible bifunctional electrodes for both oxygen evolution reaction (OER) and hydrogen evolution reaction (HER). The NiCoFe/NF electrode exhibits exceptionally high catalytic activity, requiring overpotentials as low as 220 and 50 mV, respectively, for OER and HER to occur. In a water electrolysis cell comprising of two NiCoFe/NF electrodes, an overall cell overpotential of merely 300 mV is required to deliver a stabilized current density of 3 mA cm−2. The ternary electrocatalyst also exhibits prolonged stability under both continuous and intermittent electrolysis and can be used for oxygen evolution and hydrogen evolution reversibly without degradation.
