Iyini i-AMONIUM (META)TUNGSTATE HYDRATE?

I-Ammonium metatungstate (AMT) ingesinye sezandulela ze-tungsten carbide (WC) catalyst.I-surface morphology kanye nokusatshalaliswa kosayizi wezinhlayiyana zezinhlayiya ze-WC kuthintwa izakhiwo zezandulela zayo, futhi ekugcineni kuthinte umsebenzi wayo okhuthazayo.

Isicelo

Ingasetshenziswa njengesivikelo ekudleni futhi ingengeza i-zinc edingwa umzimba womuntu.Umthamo ungabhekisa ku-sodium benzoate, futhi umphumela wawo ungcono kunalowo we-sodium benzoateI-ammonium tungsten oxide hydrate isetshenziswa kabanzi njengempahla eluhlaza yokuhlanganiswa kwama-tungsten catalysts, asetshenziswa ekuphenduleni okuhlukahlukene njenge-oxidation, i-hydroxylation, i-hydrogenation kanye i-polymerization.
