Preparation of titanium nitride/oxynitride nanotube array via ammonia-free PECVD method for enhancing supercapacitor performance

Phase Engineering of Titanium Oxynitride System and Its Solar Light-Driven Photocatalytic Dye Degradation, H2 Generation, and N2 Fixation Properties

“…Notably, the oxynitride phase of many conventional oxide systems is not known and less explored, which is often due to the lacking of (i) identifying and developing suitable precursors and (ii) insights into their phase formation mechanism . Synthesis of conventional oxynitrides requires nitriding of oxide in the presence of a suitable nitrogen-rich compounds . Whereas, in some cases, an oxide-based phase itself should be engineered or formulated as a precursor in such a way that it could be easily converted to an oxynitride system by nitriding it in an ammonia gas environment, which often leads to the formation of a system known as “atypical” oxynitrides. , For instance, it is largely reported that there is no unique crystal structure for titanium oxynitride, and it is always a mixture of TiO 2 and TiN, even if it is grown intrinsically .…”

Engineering functionalization and properties of graphene quantum dots (GQDs) with controllable synthesis for energy and display applications

“…In a recent study by Mouchani et al GQDs were electrophoretically deposited onto titanium nitride nanotube arrays (TiN) to synthesize a TiN/GQD heterostructure, which was then incorporated as an electrode in supercapacitors. 270 The paper reveals that, as shown in Fig. 10a, the addition of oxygen-functionalized GQDs resulted in the formation of C-O-Ti bonds, enhancing the conductivity of TiN and increasing the electrode surface area.…”

Depth profiling analysis of the nitriding layer formed by gas nitriding of Ti13Nb13Zr alloy

“…Thus, the peaks at the binding energies of 456.50 and 462.05 eV were believed to come from the Ti-N-O bond in the TiN x O y compounds. Notably, some reports considered that the characteristic binding energies range of the TiN x O y compounds might overlap that of the TiN satellite, and the peaks of the TiN x O y compounds and satellite were sometimes fitted into a single peak [13][14][15]. In N 1 s core-level spectrum (figure 3(c)), the peaks at the binding energies of 397.18 and 394.60 eV corresponded to the N-Ti bond in the TiN and the N-O bond in the TiN x O y , respectively, while the peak at 399.73 eV could be interpreted as the satellite feature of the TiN.…”
