“…Compared with NiO and (Ni (OH) 2 , the prepared NiÀ P showed better OER activity (Figure 3e) attributed to the structural and component virtues and the generated active oxidized nickel species during the electrochemical process. Pei et al [26] reported facile fluorination of FeÀ Co PBA approach to preparing nanocubic FeÀ Co fluoride (FeÀ CoÀ F) which exhibited excellent OER activity due to the porous cubic morphology, the coexistence of metal-F and metal-O bonds. Ni and Fe based selenides were synthesized in our group with NiÀ Fe PBA as precursors, which exhibited higher electronic conductivity and better OER activity in comparison to the oxides counterparts.…”

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.

In recent years, research efforts have been focused on the design and fabrication of highly efficient catalysts for liquid fuel cells, because the use of these cells is an important approach for alleviating environmental pollution and energy crises. However, the limitations of the catalytic performance of industrial Pt/C have strongly hindered the development of these fuel cells. The catalyst morphology has a strong impact on its performance; nanostructured catalysts are preferred as they offer large specific surface area and more exposed active centers. In view of this, many catalysts with unique structures have been synthesized in recent years, all of which show excellent catalytic performance characteristics. Despite these achievements, few efforts have been made to survey this field comprehensively. Herein, the recent advances in catalysts for liquid fuel cells are summarized, with a focus on noble metal catalysts with unique morphologies such as nanowires, nanosheets, and assembly structures. Their formation mechanisms are discussed critically. The relationship between the unique morphologies and excellent performance of these catalysts is also explored. This work may provide guidelines for the further development of liquid fuel cells.

Layered double hydroxides (LDHs) are very promising but still far from satisfactory for catalyzing the electrochemical oxygen evolution reaction (OER) in water electrolysis. Herein, it was found that the catalytic performance of iron–nickel LDHs for OER can be largely boosted by a facile and controllable fluoridation approach at low temperatures. Temperature dependence of the crystal structure and surface chemical state was observed for the simple fluoridation of the iron–nickel LDH. However, no significant surface roughness and electrochemical active surface area increases were found, which was probably owing to the structure change from nanosheets to nanorods. Significant improvements in the performance, including the catalytic activity, stability, efficiency, and kinetics, were found compared with the pristine iron–nickel LDH. Specifically, iron–nickel fluoride obtained at 250 °C afforded the lowest overpotential of 225 mV (no iR correction) to drive 10 mA cm−2 loaded on an inert glassy carbon electrode with a small Tafel slope of 79 mV dec−1, outperforming the noble‐metal IrO2 catalyst and most of the similar Fe–Ni based catalysts. The performance improvement could be mainly attributed to the phase‐structure transfer from metal−O bonding in the FeNi‐LDHs to metal−F bonding after fluoridation, which means it is easier to form the real active sites of Fe‐doped high‐valence Ni‐(oxy)hydroxide over the iron–nickel fluoride surface.
