“…Theoretical calculations demonstrated the ability of nitrogen species to adsorb at the surface of noble metals as well as transition metals, [25] indicating that zirconium is more likely to bind nitrogen atoms than hydrogen atoms; thus, Zr is expected to boost the selectivity of NRR and thereby raising the Faradaic efficiency [26,27] . ZrO 2 is a stable compound, and its central element zirconium possesses a vacant orbital that is apt to receive lone pair electrons of N 2 molecule σ orbital, beneficial to weaken the N≡N bond [28,29] …”

“…[26,27] ZrO 2 is a stable compound, and its central element zirconium possesses a vacant orbital that is apt to receive lone pair electrons of N 2 molecule σ orbital, beneficial to weaken the N�N bond. [28,29] Considering the low-down solubility of nitrogen in the commonly used 0.1 M Na 2 SO 4 , metal-organic frameworks (MOFs) with massive surface area and ordered multi-space three-dimensional structure can primely adsorb and store nitrogen by regulating the electronic structure of transition metals in their lattice. [30][31][32] This simple by high temperature pyrolysis preparation of metal organic crystal materials, on the one hand, has the high electrical conductivity, enhance the internal mass transfer and charge transfer catalyst.…”

Electrochemical synthesis of ammonia via nitrogen reduction reaction is a rational route to save energy and relieve pollution compared to the traditional Haber-Bosch process. In this report, ZrO 2 nanosphere derived from thermolysis of Zr-based biphenyl-4,4'-dicarboxylic acid MOFs (ZrO 2 /C) as a non-noble metal catalyst with large specific surface area and porous structure is proposed to fix nitrogen to ammonia at ambient conditions. Such catalyst achieves Faradaic efficiency of 11.86 % and a NH 3 yield rate of 10.72 μg h À 1 mg À 1 cat. at À 0.6 V vs. the reversible hydrogen electrode in 0.1 M Na 2 SO 4 . First-principles calculations confirm the alternating reaction at the catalyst surface.

“…In particular, vanadium in the pentavalent state (V 2 O 5 ) is yellow due to the charge transfer transition from O 2p (II) to V 3d (V) . V-ZrO 2 is a well-known inorganic yellow pigment prepared by various conventional and non-conventional methods, evidencing the incorporation of V into ZrO 2 that induces the yellow hue in the resultant pigment material . Gopal et al reported the abnormal perception in the optical property of V 5+ -substituted BPO 4 .…”

Luminescent yttrium phosphate is engineered into an environmentally benign near infrared (NIR) reflective yellow pigment by the substitution of bismuth and vanadium metals in the host lattice. A series of YP (1−x) V x O 4 (x = 0, 0.05, 0.1, 0.15, 0.2, and 0.4), Y (1−y) Bi y PO 4 (y = 0.1 and 0.3), and Y (1−y) Bi y P (1−x) V x O 4 (x = y = 0.2, 0.4, and 0.6) were prepared by the precipitation method. Secondary phase was noticed at x = 0.2 and y = 0.2 while substituting vanadium and bismuth, respectively, due to high ionic radii of the dopant ions. Co substitution of vanadium and bismuth in the YPO 4 lattice enhanced both NIR reflectance and yellow color of all the fabricated materials. XPS spectra proved the presence of trivalent bismuth and pentavalent vanadium in Y 0.4 Bi 0.6 P 0.4 V 0.6 O 4 . Due to the substitution effect, a more defined morphology was noticed, which enhanced the scattering co-efficient of the fabricated materials; hence, the NIR reflectance of the materials was increased from 68% (YPO 4 ) to 83% (Y 0.4 Bi 0.6 P 0.4 V 0.6 O 4 ). Chemical and thermal stability test of Y 0.4 Bi 0.6 P 0.4 V 0.6 O 4 confirmed the color and strength of the designed pigment. With good yellow hue (b* = +56.06), high NIR solar reflectance (R* = 83%), and good stability, Y 0.4 Bi 0.6 P 0.4 V 0.6 O 4 can act as an environmentally benign cool yellow pigment.

“…The ceramic pigment is a kind of decorative material used for the painting of ceramic products [3,4]. It can be divided into tin-based [5], zirconium-based [6], spineltype [7], rutile-type [8], corundum-type [9] and encapsulated ceramic pigments [10]. It can also be divided into high-temperature and low-temperature pigments.…”

Novel yellow to blackish green Ni-doped aluminium titanate (Al2TiO5) ceramic pigments were synthesized by solid-state reaction method at 1400 ?C. Effects of nickel doping content on phase composition, microstructure, optical properties and stability were studied. The results show that the higher content of Al2TiO5 phase and the reduction of the lattice distortion of aluminium titanate could be attributed to the entry of nickel ions into aluminium titanate lattice resulting in the formation of solid solution. Ni-doped aluminium titanate ceramic pigments show exceptional glaze colouring and are expected to be promising high-temperature pigments.
