| description | Abstract The crystallization of oxide coating layer on base metal electrode (BME) has facing challenges for a long time. In this paper, a sol‐gel method was used to coat nickel (Ni) nanoparticles with polycrystalline BaTiO3 (BT). By adjusting the reaction condition, continuous and homogeneous BT coating layer was obtained based on the transmission electron microscopy (TEM) observation. Powder X‐ray diffraction (XRD) of the coated sample indicated that deionized water content, which can change the pH value of the reaction solvent, is the key factor to influence the crystallization of the BT layer. With the increase of the deionized water, the crystallinity of the BT layer increased, which greatly enhanced the anti‐oxidation properties of the Ni nanoparticles. When the amount of deionized water increased to 20 wt%, Ni3C impurity appeared and the properties of the Ni nanoparticles deteriorated. As a result, an optimized deionized water content of 16 wt% is adopted for the best performance of the BT coated Ni (Ni@BT) nanoparticles. |
