As a group of attractive photoelectromagnetic and catalytic functional materials, metal oxychlorides have been attracting attention for electrochemical energy storage in rechargeable chloride ion battery (CIB) systems recently. Their application, however, is limited by the complicated synthesis and/or poor cycling stability. Herein, a facile strategy using vacuum impregnation and subsequent thermal decomposition at mild conditions has been developed to synthesize the FeOCl/CMK-3 nanocomposite material. Benefiting from the nanoconfined structure, a high-performance FeOCl/CMK-3 cathode, which has a high discharge capacity of 202 mAh g–1, superior cycling stability, and significantly improved charge transfer and chloride ion diffusion, is achieved. The electrolyte component is found to show a high affinity with the chlorine layer in the FeOCl phase, inducing evident expansion of the FeOCl layers along the b-axis direction and thus boosting a new potential liquid exfoliation approach for preparing 2D FeOCl material. Importantly, reversible electrochemical reactions of the FeOCl cathode material based on the redox reactions of iron species and chloride ion transfer are revealed.

In this paper, the electrochemical behavior of ethyl ferulate was investigated by cyclic voltammetry on glassy carbon electrode, and a sensitive electroanalytical method was proposed for its determination. It was shown that, in acetate buffer, the electrochemical behavior of ethyl ferulate has a good reversibility, and the currents of cathodic and anodic peaks had linear relativity with the square root of the potential scan rate, showing that ethyl ferulate presents diffusibility. The electron transfer number n and the diffusion coefficient Do were calculated to be 2 and 1.79 × 10-6 cm2 s-1, respectively. Both the cathodic and anodic peak potentials of ethyl ferulate were linearly correlative with pH value of acetate buffer, indicating that proton was involved in the electrochemical process of ethyl ferulate and the numbers of electron transfer and proton were equal. Also, it was observed that both the cathode and anode peak currents are well rectilinear to the concentration of ethyl ferulate in the range of 2.0 ×10-7 to 4.8 × 10-6 mol L-1 (r = 0.9994 and 0.9991, respectively, to the cathode and anode currents, n=8), and the detection limit is 1.0 × 10-7 mol L-1.
Two new compounds with bifunctional electrocatalytic activities have been obtained, which shows that the charge of the Keggin anions is a key factor to control the dimension of the hybrid compounds.
