I want to make a nano composite of Ni and SnO2 with different compositions. Which method should i chose for its synthesis and how can i do it???
It can be prepared by several methods.
Hydrothermal approach in basic environment (pH around 12) using Ni(NO3)2 and any Sn salt as precursor in DI water.
Ex situ synthesis. Ni nanoparticles can be slowly dispersed in a evenly dispersed solution of SnO2. This method has however chances of arial oxidation of Ni to NiO and is time consuming. Going by chemical method is thus the best.
Hope this helps!
you can try mechanical mixing of Ni and SnO2 using ball mill after that slurry can be made by addition of relevant solvent
As it is a metallic material you can try Electro Chemical Method. For this you need to choose proper cathode and anode, concentration of electrolyte solution, its pH, Applied Voltage and Current.
One can deposit or synthesis nano-composite of Ni and SnO2 by thermal evaporator by using powder of both Ni and Sn in oxygen environment, however, the composite of Ni and Sn will affect on the material properties. Moreover, the working gas pressure may also play a vital role on material properties.
You can also synthesize nanocomposite by Pulsed laser ablation in liquid methodology. At first prepare Ni and SnO2 nanoparticles individually and then mixed equal quantity of both the colloidal nanoparticles and laser irradiate for 30 to 40 min for the synthesis of nanocomposite
SnO2/Ni nanocomposite as long-life, high-rate anode for lithium ion battery
SnO2 can be spatially confined in the original site by the surrounding Ni nanoparticles
or you can find some information from following references:

Dear Dr. Hussein:
The Pechini’s method can be used to synthesized polycation as Zn7Sb2O12 or Bi3Zn2Sb3O14 and solid solution as Ni doped SnO2. There are several variants for this method but there is an optimal relation between citric acid and ethylene glycol and number of cation to be quelated. All possibilities are correlated with original Patent:
Pechini MP. Method of preparing lead and alkaline earth titanates and niobates and coating method using the same to form a capacitor. US 3330697. 1967.
The sine qua non condition of use of Pechini’s Method is that precursor salt be soluble in water and/or ethylene glycol. Such condition imposes some limitations but nothing serious. Furthermore, salts of distinct nature can be solubilized to attain further composition of oxide. Common salts belong to the nitrate and carbonate groups.
In specific, if SnO2 is the choice, a precursor salt soluble in water/ethylene glycol is necessary. See, SnO2 is a type of Top-100 commodity meaning that any product discovered and fabricated gives further increasing in the international-price of SnO2.
Unfortunately, tin salts type nitrate and carbonate are not feasible. But tin citrate can be synthesized in a lab, with simple apparatus. The technique is based on classical Patent:
Besso MM. Tin salts of citric acid and method of preparation. US Patent. 3.213.120. 1965.
From this, chemical synthesis can be carried out via Pechini's Method or Modified Polyol Method or another

In this paper i prepared Co-SnO2, similarly i am able to synthesis Ni-Sno2 also. replace cobalt by nickel precursor.
