“…In order to investigate the catalytic performance of the obtained Fe 3 O 4 -Ag nanocomposite, we selected 4-NP and 2-NA as model molecules to characterize the process. [36][37][38][39][40][41][42][43][44][45] In the catalytic experiments, fresh NaBH 4 (20 mL, 0.01 M) solution was added to 2-NA or 4-NP solution (2 mL, 5 mM) at room temperature. NaBH 4 was used as a reducing agent for this catalytic reduction reaction.…”

“…Szeto et al used TiO 2 as photocatalysts to study the effects of different lighting and atmosphere conditions on MO destruction [16]. However, the disadvantage of semiconductor photocatalysts is that their catalytic efficiency is low [17]. Therefore, it is urgent to design a kind of efficient, environmentally friendly, and economical multifunctional nanocomposites (NCs) for removing MO from wastewater.…”

“…Although it is difficult to degrade 4-NP due to the high stability and low solubility of 4-NP in water, many semiconductor nanomaterials (such as, ZnO [ 5 ], Cu 2 O [ 6 ] and TiO 2 [ 7 ]) and various methods (e.g., typical photocatalysis and chemical catalysis [ 8 ]) have been developed to solve the pollution problems of 4-NP. Generally, the catalytic conversion of 4-NP to 4-aminophenol (4-AP) is an imperative process, using excess sodium borohydride as the reducing agent, not only because 4-AP is less toxic than 4-NP, but also because 4-AP is in demand on the market in many industrial fields [ 9 ]. Unfortunately, the reduction process of 4-NP to 4-AP is very slow by NaBH 4 alone.…”
