Thermo-stimulated evolution of crystalline structure and dopant distribution in Cu-doped Y-stabilized ZrO2nanopowders

Abstract: Nowadays, one of the renewable energy technologies is the development of fuel cells, metal-air batteries and water splitting devices [1-4]. However, most of the materials used for these purposes have low catalytic activity, high cost and low durability. For instance, platinum based catalysts, being the most used for oxygen reduction [4], suffer from high cost and scarcity. However, it was demonstrated that platinum-ruthenium nanoparticles can be uniformly distributed in nitrogen-doped graphene aerogel [1]. The… Show more

“…[12] However, for the samples of R-set, its signature is more pronounced (Figure 2, curves 5, 5', 6, 6'). This finding agrees with XRD results showed appearance of monoclinic phase with contribution being less than 3% even at T C ¼ 800 C. [15] Obviously, such amount of monoclinic phase is insufficient for its detection by ATR technique. With increasing T C up to 1000 C, the contribution of monoclinic phase in XRD patterns rose up to %70% [15] and its presence is unambiguously detected by ATR spectra.…”

With increasing T C up to 1000 C, the contribution of monoclinic phase in XRD patterns rose up to %70% [15] and its presence is unambiguously detected by ATR spectra. However, for T C ¼ 1100 C, the monoclinic phase content does not change practically, while the contribution of cubic phase increases slightly ( Figure 2).…”

“…Therefore, to discriminate unambiguously these phases, the peaks in the range of 2q=73-75° are usually used [31][32][33] because cubic ZrO2 phase shows in this range only a single peak (at 2q~74.33°), while the tetragonal phase demonstrates two peaks (at 2q~73.05° and 74.58°). Since XRD peak positions depend on the doping [31,34], further analysis of XRD patterns will be performed for this specific range taken into account the number of XRD peaks only.…”
