Dependence of Photocatalytic Activity on the Morphology of Strontium Titanates

Strontium titanates were prepared with different morphologies by varying the ratio of solvents used during synthesis. The effects morphology and solvent (ethylene glycol to water) investigated both on structure photocatalytic activity samples. Structural properties determined X-ray diffraction, scanning electron microscopy, diffuse reflectance spectroscopy, nitrogen adsorption measurements. samples was evaluated oxidation phenol reduction carbon dioxide. notably influenced morphology, strontium carbonate content, primary crystallite size, specific surface area Samples at low ethylene water ratios spherical, while ones high could be characterized predominantly lamellar morphology. former found have highest efficiency for degradation, sample most well-defined proved best CO2 reduction.
