The synthesis of nanostructures are very various, and the most of scientists always
fabricate them by the coprecipitation method at pH = 10.5-11. If we prepare these nanocatalysts for
partial oxidation of methane (POM), processes to transforme methane gas into hydrogen or
synthesis gas (H2 + CO) for obtaining exact green fuel H2 gas at different pH, what will be
occurring?, and what is the influence of pH on nanoemulsion, nanofluids, nanostructures, and
finally the application in syngas process? In this study we prepared many different nanoparticles
containing AlCeO2, SiO2, SiAl2O3, SiMgO, SiO2Al-MCM-41 nano mixed oxides sized (1-2 nm) at
various pH (7, 8, 9, 11) by new coprecipitation and combine with nanofluids method using different
direct agent surfactant, stabilizer, binder, alcohol solvent, dispersant and variable chemical pH
controllers. The prepared nanostructures were characterized by common techniques such as SEM,
TEM, XRD, Raman, FTIR, BET and TPR analysis at various pH. Also many marvellous and new
mixture of nanotubes-nanoclay and nanotubes-nanocomposites with high methane conversion were fabricated by CuOx and NiOx sputtering test followed coprecipitation
method at pH 9, for POM reactions used in petrochemical industry for the first time.
