“…Cobalt nanoparticles encapsulated in Co 0.15 @ARC foreshadowed more active defect sites and stronger electronic transfer. 64 The OER η 10 value of Co 0.15 @ARC was comparable to those of some previously reported biomass-derived electrocatalysts catalysts (Table S2), such as CoP-0.6 (250 mV), 65 Ni−CoSe 2 (325 mV), 66 CMO@ NC/450 (272 mV), 67 and Co/BCTs-5 (330 mV). 68 The impact of the Co-doping concentrations on OER performances was also studied.…”

Water splitting represents a promising method for hydrogen production. However, the development of bifunctional electrocatalysts that are capable of fostering the oxygen evolution reaction (OER) and the hydrogen evolution reaction (HER) efficiently remains a significant challenge. Herein, we report an efficient and stable catalyst (Co 0.15 @ARC) by encapsulating cobalt nanoparticles in the biomass-derived carbon. Electrodes fabricated from Co 0.15 @ARC exhibit both excellent OER and HER performances in 1 M KOH solution: 320 mV for OER and 172 mV for HER to reach the current density of 10 mA cm −2 . Moreover, when employed for electrochemical overall water splitting, a current density of 10 mA cm −2 is achieved at just 1.64 V, underscoring the significant potential of Co 0.15 @ARC for efficient overall water splitting applications. The inherited porous structures after carbonization, uniformly dispersed Co nanoparticles, and the excellent electrochemical active surface area of Co 0.15 @ARC collectively enhance reaction kinetics, enabling efficient performances in OER and HER. This work may provide a practical strategy for exploring efficient bifunctional electrocatalysts for overall water splitting.

“…The scan rate for the HER polarization curve was 5 mV s À1 , while for the OER and water splitting it was 1 mV s À1 , in order to minimize the background current and the influence of nickel oxidation peaks. Tafel slopes were calculated from the LSV curves, while the double-layer capacitance (C dl ) was obtained by CV at different scan rates (10,20,30,40, and 50 mV s À1 ) within the non-faradaic range (1.12-1.13 V). Electrochemical impedance spectroscopy (EIS) was conducted over a frequency range of 10 5 Hz to 10 À2 Hz.…”

Sustainable energy development can no longer be met by fossil fuels alone. Hence, electrochemical water splitting containing oxygen and hydrogen evolution reactions is appealing as a clean energy pathway. As respects the water splitting efficiency which is largely determined by the selectivity, durability, and intrinsic activity of the electrocatalysts, one of the most challenging questions when studying these materials is “which category of electrocatalysts will show the best performance in this issue?” The best electrocatalysts for water splitting still come from noble metals. Although these materials show particularly good efficiency, but due to the scarce resources their massive use is limited. Therefore, the noble metal‐free materials due to their stability, efficiency, abundance and variety of reaction sites were introduced as an interesting candidate for electrochemical water splitting reactions. In this review, based on the important above‐mentioned points, our attention was focused on key categories based on transition metals (TMs), metal organic framework derived (MOF‐derived), carbon‐based hybrids, graphitic carbon nitride (g‐C3N4) hybrids, and bio‐assisted electrocatalysts. These compounds have shown significant activity and stability for broad electrocatalysis applications in water splitting reactions and displaying remarkable potential to replace with noble metal‐based catalysts. This comprehensive review identifies rational strategies for designing and synthesizing high‐performance novel noble metal‐free electrocatalysts for water splitting.
