Synthesis of Iron Oxide Nanoparticles (Fe3O4) 

Thank you all for reaching 1000 subscribers. You love and support to my channel "World of Nanotechnology" has been overwhelming. Your comments have helped me in improving the contents of this channel. More videos coming soon.

Thank you 😊

Thank you:)

Hello sir, will I be able to use the NP for pollutant application? Is that good enough for effective reaction ?

@ Akshay Jangam if you want to use ethylene glycol as the solvent. Just prepare the Fe2+ and F3+ solutions in 50% water and 50% ethylene glycol. After mixing the precursor solutions, heat the reaction mixture in a sealed autoclave at 180 C for 12 hours. You will get iron oxide nanoparticles.

Thanks sir

THANK YOU VERY MUCH SIR

Please subscribe, like and share my videos

Can we use it as catalyst in heterocyclic compound ? If yes, then on which compound ?

sir, thank you for the video i need your helps, i have 2 questions for you 1. how many degrees Celsius do u strir it? 2. do you store it in a nitrogen atmospheres? because Fe3O4 particles are easily oxidized in air condition. I hope your respone, many thanks, sir

Thank sir

Hello, sir I'm from Bangladesh. Currently I'm working on synthesis process with SnS2. Raw material are stannic chloride ,TAA,HCl,DI water. All these materials was stirred 1hour, no precipitate form . Then I cont. for autoclave process . Isn't there any chance to create nanoparticles? Should I do this after precipitate form?

can you please tell me about synthesis of iron oxide and cobalt oxide nano composites

Hello sir. I want to use ctab surfactant in the synthesis process. How many grams of surfactant should I use per specific mole of ferric ion????? please please answer, I should do it tomorrow!! verrry thanks sir

sir that fluid itself, does it have magnetic force, does it respond to iron objects other than magnets

What is the initial step to identify iron oxide nanoparticles

Sir how to make/ buy nanofluids for experiment on internal combustion engine For our research paper work.

Thank you all for 10000 views

Fe2O3 , you can made it by high current electrolysis of Iron in water also it's a N type semiconductor but its very hard to make ; )

Sir, thank you for this video. We are synthesizing MNPs by using ferrous and ferric salts. We are not sure about the rpm value that we should use with the magnetic stirrer. Does it have a crucial effect on nanoparticle sizes?

Hello, when i stop adding ammonia i mean that precipitation ended is it ph or what .so that yield be reporducible each time . 2nd question is : what the particle size of this prepared iron oxide nanoparticles And how to measure it . Thank you in advance sir

Hello! I am currently synthesizing MNPs in a similar way. I am having trouble getting my NPs hydrodynamic size down to 50 nm. I have a few questions: 1) what is the time span that I should add the base? I did 10 and 20 minutes time intervals and notices a 100 nm decrease in size but it's still at 300 nm 2) Do you dry your particles? If so, why? I have noticed this in many literatures and I have also noticed that after a long period in water, the particles seem to degregate. 3) do you use an acid to dissolve the dried particles? Or just water? Sorry for the ton of questions but with all the papers I have read, I can't get the specifics that I need to get quality NPs.

In magnetite fe3O4, the fe3+ concentration must be twice of fe2+ which you didn't do that. 2Fe3+ + Fe2+ + 8OH- - - - > Fe3O4 + 4 H2O

Sir what is the volume of the solution used?

please make video on preparation mnf2 &cnts

Thank sir but uv visible depend upon turbid and transparent solution and iron oxide is insoluble in water and I read somewhere that use methanol so can we use methanol or it intrupted and change wavelength

Is youre Fe2O3 have brown colore?i saw it in black colore

Sir can u share the research article of this experiment

Thank sir but in summer season lab temperature is about 45- 47c and is iron nanoparticle is light sensitive? So can I kept in refrigerator Temperature ( 4c)?

how to ta make calculation...

I wanted to know if you can help me by telling me the materials/chemicals required to form nano-tungsten oxide dihydride using simple anodizing process.

Please tell me hat sovent you used for Feso4 and Fecl3 solution?

Sir how did you perform filtration? And also can you give some ideas about the characterisation of the above NP produced.

Sir what is the role of teflon sealed autoclave and in the place of teflon sealed autoclave what equipment use.

Hello. Could you pls tell me the volume of the chemicals used in the video(different from the one in the description box) as I’m using the 1M and 2M ones. Thank you. P.S. if you could pls reply ASAP I would really appreciate it. Thank you!

Sir upload the video for preparation of ferric pyrophosphate nanoparticles as soon as possible.

can you explain for sol gel method using ferric nitrate and ethylene glycol for preparing iron oxide magnetic nanoparticles sir

What is the condition and temperature of storing iron nanoparticles in glass vial

Sir what is difference between synthesis of iron oxide nanoparticles and chemical method for synthesis of iron oxide nanoparticles is the property are different because green synthesis iron oxide to use for water cleaning ,dye removal not use for medical purposes. can you pls provide me link regarding this problem or some research paper

thank you but i need the reference please

Hello sir , I will use zetasizer to measure particle size how I deal with the dried nanoparticles in whati should dissolve? Can I use citric acid to reduce particle size iam using nanoparticles in drug delivery

What amounts should i use when using ferric chloride hexahydrate and ferrous sulphate heptahydrate Thank you so much

Sir for how long he have to dry the iron oxide ppt ?? And what should be the temperature?

Sir what is the procedure of characterisation of iron oxide nanoparticles by uv visible spectroscopy that how to make solution for uv visible spectroscopy

Good afternoon sir Your video very useful our research work, sir can you please attach the paper of this experiment. And sir please help, how to synthesised FeNPs using plant extract

I think , these asprepared particles will not be nano in size because for nano size you need the lowest concentration and a caping or stablizing agent .

sir please provide the reasearch paper of this experiment.

Hi sir iron needile repel function chemicals name

hello sir most articles magnetite should e synthesized under a nitrogen atmosphere to protect it from oxidation to maghematite?but In your labratory you did not work at nitrogen atmosphere why is so ???
