Is there any paper witch describe the reduction of 4-Nitrophenol without using any reducer agent/ in situ reduction using a nanocatalyst?
Mr. Hicham,
You can try this:
Central European Journal of Chemistry December 2008, Volume 6, Issue 4, pp 592–599.
A reduction reaction without a reducing agent does not exist. You might be the first who discover it. I would recommend you to remove your post
Bojidarka B. Ivanova How the paper you advised relates to the question
Hicham Abou Oualid You recommended this paper. How did it help you?
I recommended just his reply not his paper.
Thank you professor for your remarks.
why should I remove this post? it is a big challenge for me. I will try it when I will have acces to laboratory. For the moment, I cann't
IUPAC definition
reduction. The complete transfer of one or more electrons to a molecular entity (also called 'electronation'), and, more generally, the reverse of the processes described under oxidation (2) and (3)."
Reduction of nitrophenol requires a source of electrons (reducing agent). A catalyst makes a reaction faster. Your question, as it's formulated, shows your knowledge of basics of chemistry. Therefore , it would be better to remove your question to avoid negative comments.
I think if you remove the words "without using any reducing agent" your question could make more sense. If you did this might be what you are looking for: Article Kinetic Analysis of the Catalytic Reduction of 4 Nitrophenol...
Yurii V Geletii Thank you for your explanation. Let me ask again, I think my question is not clear. I have just started to use some reducer agent like NaBH4 and Hydrazine. I know we can not reduce 4-Nitrophenol to amino phenol without using a reducer agent (this is what you explain above). I used catalyst in this reaction. my question is: if we can have a new material which can act as a reducer and a catalyst (active surface for adsorption and diffusion and charge transfer) I am a beginner in this reaction, so this is my question. Thank you again for your comments.
The statement " material which can act as a reducer and a catalyst " is not consistent with a definition of the term "catalyst." A catalyst is a third reactant. A reducer and and oxidizer do not react directly in a catalytic reaction. If they react directly, this is not a catalytic reaction.
Yuri, Since we are being a little picky I figured I'd point out that many catalysts actually do temporarily "react" with one or more of the reactants to create an intermediate that will then react with the other reactant(s) and return the catalyst to its original state. If the catalyst is consumed it is not really a catalyst but it usually must temporarily react/interact in some way with one or more reactants in order to create a reaction pathway that increases the reaction rate
Yes, Rick, I agree. Your comments is consistent with my: " A catalyst is a third reactant."
Hello Abou Oualid Hicham,
PdNPs within macroporous structure catalyses the reduction of 4-nitrophenol by NaBH4 very efficiently, without poisoning of the catalyst for more than 10-15 cycles. For more details please see the paper: Article 3D-macroporous chitosan-based scaffolds with in situ formed ...
all articles confirmed that the reduction reaction is not possible without the addition of catalysts.
Razieh Mirsafaei What the reduction reaction and what articles? Spontaneous (without any catalyst) redox processes are very common. Your answer is very confusing.
