“…While the hysteresis loop suggests the presence of numerous mesopores, the significant N 2 absorption at P/P 0 > 0.95 is related to the macropores in the sample. 42,43 At P/P 0 < 0.1, the negligible N 2 absorption suggests a quite limited amount of micropores. According to the isotherm, the pore size distribution of the sample was calculated.…”

Iron oxide (Fe 2 O 3 ) is emerging as a potential anode alternative for lithium-ion batteries (LIBs) due to the merits of high specific capacity, environmental friendliness, and costeffectiveness. However, trapped by unsatisfactory cycling stability and rate capability, further modification is needed for Fe 2 O 3 to achieve practical requirements. In this study, a Fe 2 O 3 -based composite anode (namely Fe 2 O 3 @HA-Fe-BPDC) with interlocked structure was designed and synthesized for pursuing enhanced electrochemical properties. Benefiting from the porous structure, abundant active sites, and good tolerance to volume expansion, the as-prepared electrode exhibits significantly boosted rate capability, excellent specific capacity, and satisfactory reversibility. Typically, the Fe 2 O 3 @HA-Fe-BPDC anode provided an excellent specific capacity of 708 mAh g −1 at 0.1 A g −1 and remained at a high level of 332 mAh g −1 at 1 A g −1 , delivering significantly improved rate performance than Fe 2 O 3 . Additionally, outstanding capacity retention (95.4%) was achieved at 1 A g −1 after 600 charge/discharge cycles. The strategy based on the facile coprecipitation for fabricating Fe 2 O 3 and MOF composite electrodes provides a feasible technique to develop a high-performance anode for LIBs.

Optoelectronic biointerfaces have gained significant interest for wireless and electrical control of neurons. Three–dimentional (3D) pseudocapacitive nanomaterials with large surface areas and interconnected porous structures have great potential for optoelectronic biointerfaces that can fulfill the requirement of high electrode‐electrolyte capacitance to effectively transduce light into stimulating ionic currents. In this study, the integration of 3D manganese dioxide (MnO2) nanoflowers into flexible optoelectronic biointerfaces for safe and efficient photostimulation of neurons is demonstrated. MnO2 nanoflowers are grown via chemical bath deposition on the return electrode, which has a MnO2 seed layer deposited via cyclic voltammetry. They facilitate a high interfacial capacitance (larger than 10 mF cm−2) and photogenerated charge density (over 20 µC cm−2) under low light intensity (1 mW mm−2). MnO2 nanoflowers induce safe capacitive currents with reversible Faradaic reactions and do not cause any toxicity on hippocampal neurons in vitro, making them a promising material for biointerfacing with electrogenic cells. Patch‐clamp electrophysiology is recorded in the whole‐cell configuration of hippocampal neurons, and the optoelectronic biointerfaces trigger repetitive and rapid firing of action potentials in response to light pulse trains. This study points out the potential of electrochemically‐deposited 3D pseudocapacitive nanomaterials as a robust building block for optoelectronic control of neurons.

Hydrogen is the energy carrier with the highest energy density and is critical to the development of renewable energy. Efficient hydrogen storage is essential to realize the transition to renewable energy sources. Electrochemical hydrogen storage technology has a promising application due to its mild hydrogen storage conditions. However, research on the most efficient electrochemical hydrogen storage materials that satisfy the goals of the U.S. Department of Energy remain open questions. All of the above require strategies for designing new hydrogen storage materials. This review provides a brief overview of hydrogen preparation, hydrogen storage, and details the development of electrochemical hydrogen storage materials. We summarize the electrochemical hydrogen storage capabilities of alloys and metal compounds, carbonaceous materials, metal oxides, mixed metal oxides, metal−organic frameworks, MXenes, and polymer-based materials. It was observed that mixed metal oxides exhibit superior discharge capacity and cycling stability. The review indicates that it is vital to create novel materials with large surface area, active-conductive profiles, and low cost. We describe the challenges, gaps, and future perspectives of electrochemical hydrogen storage materials, and hope that the review could draw more attention to the development of electrochemical hydrogen storage materials with high hydrogen storage capacity, high safety, high cycle stability, and low cost and promoting their practical applications.
