Clean water is a prerequisite for health living and smooth eco-fundamental networking. However, the dye industry which is contributing remarkably to the world economic growth is equally contributing to the drastic reduction in the availability of clean water and this has become a global challenge. Notably, conventional methods and materials have been used to remove dye pollutants, but they encountered criticism due to harmful chemical employment and the inability to completely mineralize stubborn dyes. Interestingly, the photocatalytic degradation method using cheap biopolymeric metallic nanoparticles (BMNPs) is a trendy cutting-edge practice and have demonstrated to be an eco-economical approach that can completely mineralize dye pollutants into non-toxic molecules. This paper is a review of original research work that photocatalytically used BMNPs for the remediation of dye pollutants. From the study, it was observed that the highest reported dye degradation efficiency was 100% and the shortest degradation time was < 1 min. Various BMNPs can be reused for up to 7 cycles with over 85% recovery of dye and over 75% efficiency was recorded for spent BMNPs after the nth cycle in most cases. It was also observed that chitosan is the most commonly employed biopolymer for BMNPs. In the end, this study provides innovative frontiers and future research hotspots that can spur the application of BMNPs to a new level in real-life scenarios for sustainable water security and effluent treatment schemes.
