Kausar Rajar

yes you can keep them oven at moderate temperature

Muhammad Amjad

Any microwave oven like Mars 6 may also be used for heating the nanosuspension for its microwave based heat treatment and then normalizing to ambeient temperature within ovan.

Mostafa Y Nassar

I think a microwave oven will be a good choice as mentioned by Dr. Muhammad Amjad.

Thank you for your answers.

It is unclear to me whether to use catalyst support (silica or alumina) for Au-Ag nanosuspension. Can you suggest any method to deposit this nanosuspension on support.

I was thinking to anneal use Au-Ag nanosuspension without any support but some literatures suggest that these particles may agglomerate under heating at 500 degree C.

Please provide your suggestions regarding the incorporation of supports for synthesized Au-Ag nanosuspension.

I am currently interested to study the surface segregation of Ag in AuAg nanoparticle(NP) using techniques such as XPs. Will support affect the surface segregation?
