However, traditional intercalation routes including ion exchange still suffers from low interaction and slow charge transfer, etc. Herein, a pre-adsorption followed by in-situ structural transformation strategy is developed in the example of Ca<sup>2+<\/sup>-intercalated Bi<sub>2<\/sub>O<sub>2<\/sub>CO<sub>3<\/sub> from the precursor of Ca<sup>2+<\/sup>-adsorbed BiOCl. Meanwhile, the concept of \u201celectron-donation-ion-intercalation\u201d is proposed. The electron-donating ability of Ca species not only induces significant charge redistribution toward O atoms, increasing the electron density around oxygen sites and elevating the energy state of O 2p orbitals, thereby effectively narrowing the bandgap from 3.10 eV in pristine Bi<sub>2<\/sub>O<sub>2<\/sub>CO<sub>3<\/sub> to 2.25 eV, but also modifies the charge transfer pathway, enabling ultra-fast and efficient separation of photogenerated carriers. This also promotes the participation of charge carriers in surface reactions, rather than their localization within intrinsic defects. Consequently, the first-order kinetic constant for the degradation of RhB under visible light irradiation is enhanced by 17.33 times over optimized BiOC-Ca-3 compared to the pristine sample. This work offers an in-situ transformation approach for constructing ion-intercalated 2D materials and gives a novel insight into the enhanced photocatalytic activity of cation-intercalated catalysts.<\/p>\n","protected":false},"featured_media":5262,"template":"","meta":{"_acf_changed":false},"schedule":[],"speaker-category":[],"class_list":["post-5259","speaker","type-speaker","status-publish","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.6 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Fa-tang Li | Hebei University of Science and Technology | China<\/title>\n<meta name=\"description\" content=\"Fa-tang Li is a professor at College of Science, Hebei University of Science and Technology, China.
