I want to reduce graphene oxide by NaBH4. First 0.1 g GO prepared by the Hummer’s method dispersed in 50 ml DI water+ 100 ml ethylene glycol. After 30 min sonication, pH adjusted above 11 and then 5 ml one Molar NaBH4 solution added to the mixture and solution heated to 80 c and sonicated for 4 hours, but GO did not reduce. Can anyone help me why has not reduction happened?
Dear Reaz, this method was successful. pls following this procedure....
Reduced graphene oxide directly obtained from exfoliated graphite by hammers method.1.take graphene oxide in DD water 2.then dissolve NaBH4 in DD water. separately. and add to graphene oxide dropwise .3. stirre the whole solution and heat at 80 C for 1 hr .temperature maintance is impordant. 4.graphene can be obtained from mixture by centrifuge first and then wash with DD water several time.NaBH4 is good reducing agent than hydrazine.

Mr kumar, whats the role of centrifugation in this pro. is this about impurities or about ph, or filtering problem?...
You can use hydrazine hydrate to reduce graphene oxide.
