Efficient 4-nitrophenol reduction by a novel rare-earth-doped NaLa(MoO4)2:Sm3+/AgBr composite

Abstract

The escalation of industrial operations has resulted in a surge of 4-nitrophenol (4-NP) emissions, which is not only a significant environmental concern but also a persistent risk to public health. Addressing this issue urgently calls for the development of robust methods to eliminate such pollutants and lessen their detrimental effects on our surroundings. In our research, we have introduced an innovative approach that leverages the incorporation of rare earth elements and silver bromide into fluorescent materials, aiming to degrade 4-NP. Through a straightforward, two-step synthesis process, we have crafted a NaLa(MoO₄)₂:Sm³⁺/AgBr composite that serves a dual purpose. This novel material has demonstrated its prowess by converting 4-NP into the 4-aminophenol (4-AP) in just a span of 5 min. By offering a efficient solution, our research paves the way for the development of recyclable fluorescent materials as catalysts for environmental remediation, potentially transforming the landscape of water pollution treatment.
