Facile fabrication of faceted copper nanocrystals with high catalytic activity for p-nitrophenol reduction

Catalytic Reduction of p-Nitrophenol Using Chitosan Stabilized Copper Nanoparticles

“…Copper is a good replacement in terms of cost and material abundancy. In fact, naked and stabilized-Cu nanoparticles have been employed in the catalytic reduction of p-NP recently [9][10][11][12][14][15][16][17][18][19]. Our group has also successfully demonstrated the viability of the Cu deposited porous silicon particles towards catalyzing the reduction of p-NP in the presence of potassium borohydride [20].…”

“…Exposure to p-NP brought about risks to the environment that can eventually harm human life [1]. As such, several water treatment techniques have been employed to address the p-NP in polluted water including membrane filtration [2], photodegradation [3], adsorption [4] and chemical reduction [5][6][7][8][9][10][11][12]. Among these techniques, chemical reduction of p-NP to 4-aminophenol is favorable due to its great commercial benefits.…”

Basic concepts and recent advances in nitrophenol reduction by gold- and other transition metal nanoparticles

“…Compared with the expensive noble metal NPs, Cu is a cheap alternative with a broad potential application in nanoscience. Especially, with the help of various supports, it is considered as an effective catalyst due to its reusability and stability [136][137][138][139][140][141][142]. In addition, for 4-NP reduction the CuNPs show a better catalytic activity than other metal NPs such as Ag, Au, Pt and Pd [141,and see Ref.…”

Facile synthesis of MCM-41/nano zero-valent iron composite for catalytic reduction of p-nitrophenol

“…It can be observed that the intensity of absorption peak at 400 nm is successively decreased, while a new absorption peak at 300 nm corresponding to p-AP is appeared. Additionally, the UV-vis spectrum shows an isosbestic point between the two absorption bands, indicating that the p-NP can be directly converted to p-AP without by-product [23][24][25]. As a control experiment, the catalytic activity of BNZVI was also investigated.…”
