CuFe2O4 magnetic nanoparticles: A simple and efficient catalyst for the reduction of nitrophenol

Catalytic Activity of BiVO4-graphene Nanocomposites for the Reduction of Nitrophenols and the Photocatalytic Degradation of Organic Dyes

“…In addition, the peak at 291 nm was blue-shifted and the peak at 251 nm eventually disappeared. 39 Figure 3(c) shows the catalytic reduction of 2-nitrophenol. As can be seen in Figure 3(c), 2-nitrophenolate ions show a peak at 415 nm in the presence of NaBH 4 .…”

“…With the addition of the catalyst, the yel- low color of the aqueous solution started fading, the peak at 415 nm started decreasing, and the peak at 282 nm was redshifted. 39 The concentration of NaBH 4 was controlled and regarded to be constant during the course of the reaction. The kinetics of nitrophenol-reduction can be considered a pseudo-firstorder reaction.…”

Catalytic Activity for Reduction of 4-Nitrophenol with [C₆₀]Fullerene Nanowhisker-Silver Nanoparticle Composites

“…In previous research, the Langmuir-Hinshelwood model has been applied to the investigation of the kinetics of 4-nitrophenol reduction. [26][27][28][29] The kinetic equation can be written as ln(C/C 0 ) = −κt, where C 0 is the initial concentration, C is the concentration at time t, and κ is the rate constant. The reduction of 4-nitrophenol followed a pseudo-rst-order rate law.…”
