The bismuth-containing composite comprises bismuth oxide and a dopant element, which is one or more of titanium, nickel, copper, iron, cobalt, carbon, and nitrogen. As a dechlorination agent, this bismuth-containing composite, by selecting a semiconductor element as the dopant, can reduce the stability of the Bi-O covalent bonds in the sample, making them more susceptible to breakage under hydrogen ion attack, leading to structural collapse and the release of more bismuth ions, thus promoting the dechlorination reaction. Furthermore, after the bismuth-containing composite participates in the dechlorination reaction, the dechlorination product easily forms a heterojunction under light excitation during elution, allowing electrons to transfer to the introduced semiconductor, forming electron-hole pairs. The remaining holes on the bismuth oxychloride undergo photocorrosion, promoting the conversion of bismuth oxychloride to bismuth oxide, facilitating recycling, and improving subsequent dechlorination efficiency.
