Among the various catalysts, MnO2 is considered as one of the most outstanding metal oxides on new catalytic oxidation systems, due to its relative low price, chemical stability, and non-toxic property.
AA oxidations often come at a price: management of the coupled-proton movement.
Pd, which is comparable to Pt in the hydrogen oxidation reaction (HOR) activity and of which price is about one third of Pt, is employed as an anode catalyst.
Corrosion, wearing away due to chemical reactions, mainly oxidation (see oxidation-reduction, oxide).
The availability of methane (from natural gas) and its oxidation product, methanol, has been increasing, while prices have been decreasing, thus rendering them as attractive fermentation substrates.
In this study, an Ir3Sn CeO2/C heterogeneous catalyst is designed as low-price, alternative Pt-free electrocatalyst towards ethanol oxidation reaction (EOR) in acidic conditions.
While certain challenges like the lowest possible pressure drop over the catalyst and price considerations are common for almost all areas of oxidation catalysis, other challenges may be specific for a particular area.
Palladium (Pd) has been considered as an excellent option to replace platinum-based electrocatalysts in formic acid oxidation owing to its superb catalytic activity to Pt and cheaper material price.

Although remelting is highly beneficial from the perspective of oxidation resistance [ 38], the present results indicate that it comes at the price of the reduced crystallinity which is induced by heating above the melting temperature.
Whilst, during starvation, lipolysis of triglyceride stores might enhance fatty acid availability and drive oxidation in tissues other than the brain, the increased ATP yield comes at a price.
