Understanding the properties and structure of reactant water molecules at the electrolyte solution/electrode interface is relevant to know the mechanisms of hydrogen evolution reaction (HER). However, this approach has rarely been implemented due to the elusive local microenvironment in the vicinity of the catalyst. Taking the NiÀ CeO 2 heterostructure immobilized onto carbon paper (NiÀ CeO 2 /CP) as a model, the dynamic behavior of adsorbed intermediates during the reaction was measured by in situ surface-enhanced infrared absorption spectroscopy with attenuated total reflection configuration (ATR-SEIRAS). Theoretical calculations are used in combination to comprehend the potential causes of increased HER activity. The results show that the OÀ H bond of adsorbed water at the electrolyte solution/electrode interface becomes longer for promoting the dissociation of water and accelerating the kinetically slow Volmer step. In addition, forming the NiÀ CeO 2 heterostructure interface optimizes the hydrogen adsorption Gibbs free energy, thus increasing HER activity. Therefore, the NiÀ CeO 2 /CP electrode exhibits remarkably low HER overpotentials of 37 and 119 mV at 10 and 100 mA cm À 2 , which are close to commercial Pt/C (16 and 102.6 mV, respectively).

“…An effective strategy for constructing nanostructure engineering is to design nanocrystals confined in the refined architecture, such as core–shell structure, hollow structure, and nanotubes. Such a nanostructure not only alleviates the volume expansion effect but also shortens ion transport channels. ,, For example, CoP nanoparticles anode which enwrapped in nanotubes for LIBs is reported by Liu et al Due to the confined structure, the carbon network shell not only improves the structure stability to alleviate the volume/pressure variation but also provides abundant ion transport channels to improve the ion transport efficiency. Then, average specific capacities of 1159 mA h g –1 at 0.2 A g –1 and 524 mA h g –1 at 2 A g –1 after 900 cycles can be obtained.…”

The large grain boundary resistance between different components of the anode electrode easily leads to the low ion transport efficiency and poor electrochemical performance of lithium-/sodium-ion batteries (LIBs/SIBs). To address the issue, a Janus heterointerface with a Mott−Schottky structure is proposed to optimize the interface atomic structure, weaken interatomic resistance, and improve ion transport kinetics. Herein, Janus Co/Co 2 P@carbon-nanotubes@core−shell (Janus Co/ Co 2 P@CNT-CS) refined urchin-like architecture derived from metal−organic frameworks is reported via a coating−phosphating process, where the Janus Co/Co 2 P heterointerface nanoparticles are confined in carbon nanotubes and a core−shell polyhedron. Such a Janus Co/Co 2 P heterointerface shows the strong built-in electric field, facilitating the controllable ion transport channels and the high ion transport efficiency. The Janus Co/Co 2 P@CNT-CS refined urchin-like architecture composed of a core−shell structure and the grafting carbon nanotubes enhances the structure stability and electronic conductivity. Benefiting from the spaced-confined Janus heterointerface engineering and synergistic effects between the core−shell structure and the grafting carbon nanotubes, the Janus Co/Co 2 P@CNT-CS refined urchin-like architecture demonstrates the fast ion transport rate and excellent pseudocapacitance performance for LIBs/SIBs. In this case, the Janus Co/ Co 2 P@CNT-CS refined urchin-like architecture shows high specific capacities of 709 mA h g −1 (200 cycles) and 203 mA h g −1 (300 cycles) at a current density of 500 mA g −1 for LIBs/SIBs, respectively.
