Photocatalytic biomass valorization has proven to be a valuable approach for sustainably constructing value-added products from waste materials. The present study aimed to know about Bismuth ferrite (BiFeO3) nanoparticles combined into carboxymethyl cellulose (CMC) obtained from oil palm empty fruit bunch waste (OCMC) and used as a catalyst composite for the degradation of anionic dyes, specifically on methyl orange (MO) and congo red (CR). The parameter that affects the formation of OCMC, such as the degree of substitution (DS), depends upon the alkalization reaction time and NaOH concentrations. The highest DS was obtained at 1.562 and found at 60% NaOH with 9 h of alkalization, very close to that of the commercial CMC (CCMC) DS value. X-ray diffraction (XRD) analysis revealed that OCMC as a semi-crystalline phase and the tensile strength of OCMC film increased significantly from 0.11 MPa to 3.54 MPa as compared to CCMC. The comparative study on photocatalytic degradation of MO and CR using OCMC and CCMC reinforced with 0.8% BiFeO3 showed a minor difference in removal percentage. The efficiency removal for CCMC/BFO towards CR and MO was enhanced to 95.49% and 92.93% after a 3-h treatment, and a similar result was obtained in the case of OCMC/BiFeO3 at 92.50% for CR and 89.56% for MO, respectively. Nevertheless, it is interesting that OCMC film exhibits remarkable stability with an improvement in terms of tensile strength and stays more intact than that of CCMC.
