“…35 The reaction of molybdenum (Mo) powder with the hydrogen peroxide (H 2 O 2 ) generates a variety of species attached to 1 to 6 peroxide groups. 36 38 The chemistry of the HMTA with the peroxomolybdic acid solution generates the nuclei and forms the lattice of molybdenum trioxide (MoO 3 ) in the hexagonal phase. The interaction of NH 4 + and OH − ions (hydrolysed product of HMTA) with the peroxomolybdic species can be expressed according to the following reaction (1):…”

Formation of hexagonal-molybdenum trioxide (h-MoO₃) nanostructures and their pseudocapacitive behavior

The crystallographic structure and morphology of redox active transition metal oxides have a pronounced effect on their electrochemical properties. In this work, h-MoO3 nanostructures with three distinct morphologies, i.e., pyramidal nanorod, prismatic nanorod and hexagonal nanoplate, were synthesized by a facile solvothermal method. The morphologies of h-MoO3 nanostructures were tailored by a controlled amount of hexamethylenetetramine. An enhanced specific capacitance about 230 F g(-1) at an applied current density of 0.25 A g(-1) was achieved in h-MoO3 pyramidal nanorods. Electrochemical studies confirmed that the h-MoO3 pyramidal nanorods exhibit superior charge-storage ability. This improved performance can be ascribed to the coexistence of its well exposed crystallographic planes with abundant active sites, i.e., hexagonal window (HW), trigonal cavity (TC) and four-coordinated square window (SW). The mechanism of charge-storage is likely facilitated by the vehicle mechanism of proton transportation due to the availability of the vehicles, i.e., NH4(+) and H2O. The promising, distinct and unexploited features of h-MoO3 nanostructures reveal a strong candidate for pseudocapacitive electrode materials.

“…In the peroxidoisomolybdate system, at the high peroxide/ Mo ratio used for the preparation of the current compounds, a monomeric diperoxidomolybdate and a dimeric tetraperoxidodimolybdate are important species in the solution (Taube, Hashimoto et al, 2002;. The diperoxidomonomolybdate and tetraperoxidodimolybdate anions show very broad 95 Mo NMR signals at about À262 and À280 p.p.m., respectively, at pH 3, as was employed for their preparation in the present work.…”

The unit-cell parameters of the three title salts, namely, tripotassium, K(3)[Mo(2)(CHO(2))O(3)(O(2))(4)], trirubidium, Rb(3)[Mo(2)(CHO(2))O(3)(O(2))(4)], and triammonium μ-(formato-κ(2)O:O')-μ-oxido-bis[oxidobis(peroxido-κ(2)O,O')molybdate(VI)], (NH(4))(3)[Mo(2)(CHO(2))O(3)(O(2))(4)], which were all crystallized at pH 3, are quite similar, but the potassium and rubidium salt structures are noncentrosymmetric, whereas that of the ammonium salt is centrosymmetric. Formate acts as an O:O'-bridging ligand in the complex anion and is bound to a μ-oxido-bis(oxidodiperoxidomolybdate) unit.
