[1][2][3][4][5][6] Although major significant breakthroughs in related technologies, researchers are still looking for materials that can meet commercialized applications. For ORR, as state-of-the-art catalysts, platinumbased catalysts have poor durability, expensive cost and high sensitivity to methanol crossover.…”

Mn3O4 nanoparticles encapsulated inside carbon nanospheres supported on a carbon plate (Mn3O4@CS/CP) were designed, their bifunctional electrocatalytic performance for both, the oxygen evolution reaction (OER) at the anode and the oxygen reduction reaction (ORR) at the cathode were studied in alkaline solution. The prepared Mn3O4@CS/CP catalyst exhibits excellent electrocatalytic performance towards ORR, with less negative onset potential and long durability. Combining the results of in‐situ Fourier transform infrared spectroscopy (FTIR) and density functional theory (DFT) calculations, it is revealed that Mn3O4 acts as active site for ORR to promote the transformation of OH* into OH−. In addition, Mn3O4@CS/CP possesses an excellent electrochemical OER performances with the lower overpotential along with prosper Tafel slope and robust durability. DFT calculations show the transformation from O* to OOH* is the rate determining step for OER, and Mn3O4@CS/CP shows the minimum barrier, indicating that graphene sheet on the outer of Mn3O4 improves the transformation from O* to OOH*. The oxygen electrode activity parameter (potential difference between OER at current density of 10 mA/cm2 and ORR at current density of −2 mA/cm2) on Mn3O4@CS/CP is 0.72 V, which is superior to those of most bifunctional electrocatalysts reported to date, predicting a promising application in metal‐air batteries and fuel cells.

“…The FCP electrode gave rise to large Tafel slope of 81 mV dec −1 , whereas the PMFCP electrode had a substantially lower Tafel slope of 44 mV dec −1 . It is well known that a smaller Tafel slope indicates a faster increase of the HER rate with the increase of potential . Hence, the PMFCP sample enables a faster HER process.…”

“…Furthermore, incorporating both metal and nonmetal elements was reported to further improve the electrocatalytic activity. Liu et al [30] developed a simultaneous sulfurization and phosphorization of NiÀ Fe PBA approach to obtain quaternary (NiFe) 3 nanosheets. Density functional theory (DFT) calculation demonstrated that the active sites for OER were the unsaturated Fe and Ni atoms located on the (010) plane of (NiFe) 3 .…”

Electrochemical water splitting (EWS) is a sustainable and promising technology for producing hydrogen as an ideal energy carrier to address environmental and energy issues. Developing highly‐efficient electrocatalysts for hydrogen and oxygen evolution reactions (HER and OER) is critical for increasing the efficiency of water electrolysis. Recently, nanomaterials derived from Prussian blue (PB) and its analogs (PBA) have received increasing attention in EWS applications owing to their unique composition and structure properties. In this Minireview, the latest progress of PB/PBA‐derived materials for EWS is presented. Firstly, the catalyst design principles and the advantages of preparing electrocatalysts with PB/PBA as precursors are briefly introduced. Then, strategies for enhancing the electrocatalytic performance (HER, OER or overall water splitting) were discussed in detail, and the recent development and applications of PB/PBA‐derived catalysts for EWS were summarized. Finally, major challenges and possible future trends related to PB/PBA‐derived functional materials are proposed.
