• nanoparticles follows the approach by S. Sun et al. [84] by the reduction of platinum diacetylacetonate, Pt(acac)2 and thermal decomposition of iron pentacarbonyl, Fe(CO)5, in hexadecane-1,2-diol at about 300 °C. The chemical reactions were initiated in the presence of the surfactants oleic acid and oleyl amine

• example, defects are often preferred adsorption sites and hence are particularly chemically active. Electrically charged defects may enable electron transfer processes, which play an important role in chemical reactions in general and in heterogeneous catalysis in particular. A sketch of a binary oxide

From calculations it has been proposed that color centers are directly involved in chemical reactions [23][24], e.g., as adsorption sites due to more attractive defect-adsorbate interactions compared with the pristine
