The invention discloses a bismuth oxychloride supported cuprous oxide photocatalyst as well as a preparation method and an application thereof. The method comprises the following steps: dropwise adding a metal chloride salt aqueous solution into a bismuth salt aqueous solution, stirring at room temperature, and carrying out hydrothermal reaction to obtain flaky bismuth oxychloride; adding flaky bismuth oxychloride into a copper salt aqueous solution, dropwise adding an alkali aqueous solution, stirring, dropwise adding an ascorbic acid aqueous solution, stirring, and collecting a precipitate, thereby obtaining the bismuth oxychloride loaded cuprous oxide photocatalyst. The preparation method disclosed by the invention is simple, and Cu2O/BiOCl with a relatively good crystal form can be obtained; and compared with a pure catalyst, the number of active sites of the constructed loaded catalyst is increased. 本发明公开了一种氯氧化铋负载氧化亚铜光催化剂及其制备方法与应用。将金属氯化盐水溶液滴入铋盐水溶液中，室温搅拌后水热反应，得到片状氯氧化铋；将片状氯氧化铋加入铜盐水溶液中，然后滴入碱的水溶液，搅拌后滴入抗坏血酸水溶
