We want to use glycerine for the synthesis of nanoparticles instead of ethylene glycol..can we use that
Ethylene glycol , HO-CH2CH2-OH, is a difunctional compound so if it is reacted with, e.g. terephthalic acid (also difunctional compound having 2 carboxylic acid groups), then a polyester with linear structure is produced. If glycerin , which is a trifunctional compound that has the systematic name of 1,2,3-propane triol, is reacted with terephthalic acid, then a polyester with 3-dimensional network structure is obtained. As far as I know, nanoparticles are structure-dependent.
If you are a beginner in research, then I may suggest that you try a diol such as 1,4-butanediol HO-CH2CH2CH2CH2-OH which has an element of symmetry in its molecules similar to those of ethylene glycol molecules.
Dear Amir Ullah, you want to use it as a reactant or as a solvent ? Which type of nanoparticles you are dealing with ? Organic or inorganic ? In case it is a reactant, a 3D network is the result. On the other side, if it is only the synthesis medium, I don't see any harm in that. My Regards
Air I need answer of this question please air help...
Q: Which one is better for photocatalytic activity C3N4 or C4N4 and why?
C3N4 and C4N4 both are carbon nitride but it may have different property. so I want to know C4N4 photocatalytic activity. please help
Dear Amir Ullah, the best photocatalytic carbon based systems are those metal doped ones. Please check the following free access document. My Regards

The following document is another interesting one.

Hi;
The choice of a photocatalyst depends on its stability and especially on its absorption spectral range, i.e. the one corresponding to the photons available for photoexcitation and thus potentially for the photocatalytic process. The choice of the photocatalyst thus results from the wavelength range able to initiate this process. The two proposed nitrides have limitations when not corrected to make the material even more suitable for photocatalytic applications. They present a high recombination rate of the carriers generated by photodissociation, a low electrical conductivity and a limited specific surface. It is however possible to overcome these limitations for example by doping the materials with carbon nanotubes or with other semiconductors.
With my best regards
Yes yes dear....
Only cooling Agents role they play....
Or as a surfactants
