Synthesis and biological characterization of zirconium oxynitride thin film growth by radio-frequency sputtering

Zr-O-N coatings for decorative purposes: Study of the system stability by exploration of the deposition parameter space

“…Therefore, this can be interpreted as the result of growth and distortion of the c-Zr 2 ON 2 peaks observed in group 2, or the appearance of a new phase (e.g. Zr 3 N 4 or m-ZrO 2 ) [3,5,6,8,9,14,16,[18][19][20][21][22][23][24][25][26][27][28][29][31][32][33][34][35][36][37][38][39][40][41][43][44][45][46]51,57,58].…”

“…In that regard, zirconium oxynitride coatings have been drawing attention over the past years, due to the combination of a wide palette of attainable colors [12][13][14], good biocompatibility [15], mechanical properties [16] and corrosion resistance [17,18]. The majority of Zr-O-N films in literature have been deposited by reactive magnetron sputtering operated with different sources (DC, RF or pulsed-DC) [3][4][5][6]8,9,13,14,, and their properties have been typically tuned via the modification of reactive atmosphere [3][4][5][6]8,9,13,14,[19][20][21][22][23][24][25][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42]. As a result, the reported chemical composition of the Zr-O-N films is surprisingly limited, located in a region of the Zr-O-N ternary diagr...…”

Bending the ORR Scaling Relations on Zirconium Oxynitride for Enhanced Oxygen Electrocatalysis

“…Bulk optimisation of the representative structure of Zr 2 ON 2 gives us a cubic lattice crystal structure with lattice constant of 1.01 nm which agrees very well with the experimental value of 1.0135 nm [26] . In our study we are exploring ORR on the (111) surface of Zr 2 ON 2 slab [29–31] . It has a hexagonal lattice structure with lattice parameter a=1.42 nm and a total vacuum of 1.6 nm (with 0.8 nm on both side of the slab).…”

“…[26] In our study we are exploring ORR on the (111) surface of Zr 2 ON 2 slab. [29][30][31] It has a hexagonal lattice structure with lattice parameter a = 1.42 nm and a total vacuum of 1.6 nm (with 0.8 nm on both side of the slab). Water, being one of the products of the ORR, is expected to be present in the fuel cell, hence we investigate the possibility of water molecule(s) interacting with and dissociating on the catalyst surface.…”
