“…Synthesis of Yolk–Shell FeP@CNBs: Yolk–shell FeP@CNBs were synthesized in a two‐zone furnace. Typically, 1 g NaH 2 PO 2 was loaded into an alumina boat which was put at the center of the upstream zone, while another alumina boat containing 50 mg yolk–shell Fe 2 O 3 @C was put in the center of the downstream zone.…”

Maintaining structural stability and alleviating the intrinsic poor conductivity of conversion-type reaction anode materials are of great importance for practical application. Introducing void space and a highly conductive host to accommodate the volume changes and enhance the conductivity would be a smart design to achieve robust construction; effective electron and ion transportation, thus, lead to prolonged cycling life and excellent rate performance. Herein, uniform yolk-shell FeP@C nanoboxes (FeP@CNBs) with the inner FeP nanoparticles completely protected by a thin and self-supported carbon shell are synthesized through a phosphidation process with yolk-shell Fe 2 O 3 @CNBs as a precursor. The volumetric variation of the inner FeP nanoparticles during cycling is alleviated, and the FeP nanoparticles can expand without deforming the carbon shell, thanks to the internal void space of the unique yolk-shell structure, thus preserving the electrode microstructure. Furthermore, the presence of the highly conductive carbon shell enhances the conductivity of the whole electrode. Benefiting from the unique design of the yolk-shell structure, the FeP@CNBs manifests remarkable lithium/ potassium storage performance.

“…Furthermore, the authors also demonstrated the excellent HER activities of Ni 2 P@C‐NPs/GA in 0.5 m H 2 SO 4 and 1.0 m KOH, respectively. Similarly, Venugopal et al [ 238 ] incorporated FeP particles into a 3D porous graphene aerogel. Thanks to the high accessibility of the framework after FeP loading, the as‐synthesized FeP/GA also exhibited excellent HER activity and stability in both acidic and alkaline solutions.…”

Hydrogen (H2) has been deemed as the most promising and valuable alternative to nonrenewable fossil fuels. Photocatalytic and electrocatalytic water splitting are considered to be the most efficient and environmentally friendly approaches for the sustainable H2 evolution reaction (HER). Graphene with a 3D framework has been utilized for the HER due to its unique structure and properties, including its hierarchical network, large specific surface area, diverse pore distribution, outstanding light absorption ability, and excellent electrical conductivity. The large specific surface area and hierarchically porous structure of 3D graphene can not only maximize the exposure of active sites but also promote electron transfer and gas product diffusion. In addition, the free‐standing 3D graphene monolith is easily recycled compared with powder phase support, which can prevent the loss of active catalysts. By making full use of the aforementioned merits, 3D graphene‐based composite materials show great promise as high‐performance catalysts toward photocatalytic and electrocatalytic HER. In this review, recent advances in fabricating 3D graphene‐based composite materials and their applications in both photocatalytic and electrocatalytic HER are summarized and discussed. Furthermore, the current challenges and future vision associated with the design, fabrication, and integration of 3D graphene‐based composite materials toward HER are put forward.

“…Prussian blue analogues (PBAs), composed of metal ions and organic ligands, have been extensively applied as ideal templates for the conversion of diversified porous or hollow metal phosphides, metal sulfides, and other metal species materials. − Due to the controllable shape of PBA, the ordered pore sizes and the advantages of the synthesis method are simple. Even better, during phosphidation or sulfurization processes, the CN – of PBAs can easily generate nitrogen-doped carbon, in which it has been proven that the introduction of nitrogen atoms in carbon can promote the surface-dominated charge storage and improve electronic conductivity of electrodes. − Furthermore, the PBAs have two or more metal ions, which makes them an excellent precursor to synthesis of multimetallic phosphides via a simple one-step phosphating process .…”

Rational design, convenient fabrication, and application of double-shelled hollow architectures with well-defined morphology and multicompositions as electrodes for rechargeable batteries still remain great challenges. Herein, double-shelled Ni− Fe−P/N-doped carbon nanoboxes (defined as Ni−Fe−P/NC) were synthesized and then applied as electrode materials for potassiumion batteries (KIBs) and Li−S batteries, first. The unique architectures could not only alleviate volume changes and prevent aggregation of Ni−Fe−P/NC during cycling but could also provide efficient surface areas for infiltration of electrolyte. Additionally, nitrogen-doped carbon could improve the conductivity of the electrode. Hence, when these Ni−Fe−P/NC nanoboxes were applied as anode materials for KIBs, they delivered enhanced cycling stability (172.9 mA h g −1 after 1600 cycles at 500 mA g −1 and 115 mA h g −1 after 2600 cycles at 1000 mA g −1 ). Meanwhile, the Ni−Fe−P/NC could also be used as the sulfur host material for Li−S batteries; benefiting from its unique hollow structure, it can accommodate high sulfur loading and have strong chemical adsorption ability to polysulfides.
