Further research on the mechanism of this reaction and the scope of exchanged chromium composite material and related redox molecular sieves as solid catalyst for various solid phase oxidations is in progress.
We developed a solid-phase-oxidation-system using FAp disperse phase and vanadomolybdophosphoric acid (H3+nPVnMo12−nO40: PVn) catalysts with molecular oxygen as a new green reaction system.
X-ray diffraction and Fe and S K-edge X-ray absorption spectroscopy revealed that mackinawite was the only crystalline solid phase present, although some oxidation of the mineral had occurred.
Hollow CuFe2O4/α-Fe2O3 CuFe2O4/α-Fe2O3 ultrathin porous shell were sucomposites prepared by a facile template-induced method, withh involves the self-assembly of Fe3+ ions on the sultrathin Cu@carbon microsporous and the shellquent transformation to CuFe2O4/α-Fe2O3 through thermal oxidation and solid phase reaction.
Silicon nanomaterials are obtained by an original approach based on the direct solution phase oxidation of a solid state Zintl phase NaSi used as silicon precursor.

And then, the rest of Cu–In compound is possibly "passivated" by oxidation, and ultimately retains a solid phase.
Owing to the geologic history and reducing (anoxic) conditions at depth in the Marcellus Shale formation, parent and supporting radionuclide U (which, unlike Th, can be redox active under natural conditions) is likely to be contained in the crystal lattice of minerals or adsorbed to solid phase structures in a reduced highly insoluble (+4) oxidation state (Swanson 1961).
The model takes into account (1) advective dispersive transport of Cr III), Cr VI), lactate, and protein (mobile and immobile bacteria); (2) first-order kinetic adsorption of Cr III) and lactate; (3) conversion of solid phase β-MnO2 to solid phase MnOOH due to oxidation of Cr III); (4) dual-Monod kinetics, where Cr VI) is the electron acceptor and lactate is the electron donor.
The nonisothermal multiplicity is attributed to the exothermic propylene oxidation and thermal feedback in the solid phase.
Finally, the 500 nm magnetite incubation with native HS and reduced HS resulted in a minor overall oxidation and inconclusive changes in the solid phase (Fig. 6).
