Abstract: A BiF 3 powder sample was prepared from the purchased Bi 2 O 3 powder via the precipitation route. The photocatalytic performance of the prepared BiF 3 powder was compared with the Bi 2 O 3 powder and recognized as superior. The prepared BiF 3 powder sample was added in a plaster of Paris (POP) matrix in the proportion of 0%, 1%, 5%, and 10% by wt% to form POP–BiF 3 (0%), POP–BiF 3 (1%), POP–BiF 3 (5%), and POP–BiF 3 (10%) composite pellets, respectively, and activated the photocatalytic property under the UV–light irradiation,in the POP. In this work, Resazurin (Rz) ink was utilized as an indicator to examine the photocatalytic activity and self-cleaning performance of POP–BiF 3 (0%), POP–BiF 3 (1%), POP–BiF 3 (5%), and POP–BiF 3 (10%) composite pellets. In addition to the digital photographic method, the UV–visible absorption technique was adopted to quantify the rate of the de-colorization of the Rz ink, which is a direct measure of comparative photocatalytic performance of samples.
