Using spray pyrolysis, can I sonocate TiO2 anatase nanopowder in ethanol, mix with a deionised water dispersion of rGO and spray directly to glass?

I have a spray pyrolysis machine capable of a substrate temperature of up to 500deg C. My theory is that I should be able to sonocate TiO2 nanopowder (already in Anatase crystal form) into...

How to make a conjugated TiO2 anatase / PVA structured hydrogel with PEG as a crosslinking agent?

I've made thin films of TiO2 / PVA conjugated structures by making a Titanium Butoxide / TFA xerogel, dissolving this in dH2O, then separately dissolving PVA in dH2O, then adding the TiO2 solution...
