- Abstract
The current study aims to identify the extent to which bimetallic nanoparticles (NPS) are considered highly effective in removing p-nitrophenol (PNP) and its derivatives from wastewater by using various bimetallic NPS. Many previous studies have been conducted to determine the conversion rate and reduction cycles of all types of bimetallic NPS. The findings indicated that PNP is removed by using bimetallic NPS to help reduce it into p-aminophenol (PAP). Besides, noble metals are considered the most effective metals that can be used in bimetallic NPS for their high conversion rate, ranging from 95 to 100%. However, it was concluded that bimetallic NPS of transition metals can serve as efficient catalysts that help to reduce PNP into PAP in the presence of sodium borohydride (NaBH4) as a reducing agent. In this review, we focused on the impact of PNP on health and the challenges of removing PNP and its derivatives from wastewater. In addition, a critical analysis of various types of bimetallic NPS has been reported. Further, we also recommended establishing empirical research-based studies using real-life practical experiments and using different reducing agents such as hydrazine and sodium citrate other than NaBH4.
