Abstract
استفاده از فاز معدني در ميكروامولسيون آب در روغن جهت سنتز نانوذرات اكسيد فلزي در چند سال اخير توجهات زيادي را به خود جلب كرده است. در اين مقاله نانودرات كروم اكسيد با استفاده از روش امولسيون معكوس سنتز شد. مهم ترين مزيت اين روش كنترل آسان شرايط واكنش مي باشد. در اين مقاله همچنين ويژگي هاي كاتاليستي نانوذرات Cr2O3 مورد مطالعه قرار گرفت. اكسيداسيون الكل ها و آلدهيدهاي آروماتيك به كربوكسيلسك اسيدهاي متناظر با بازده بالا در حضور نانوذرات Cr2O3 صورت پذيرفت.
Abstract
The use of an inorganic phase in water-in-oil (w/o) microemulsion
has recently received considerable attention for preparing metal
oxide nanoparticles. This is a technique, which allows preparation of
ultrafine metal oxide nanoparticles within the size range 40 to 80
nm. Preparation of nano chromium (III) oxide studied investigated in
the inverse microemulsion system. Therefore the nucleation of metal
particles proceeds in the water capsules of the microemulsion. the
main advantage of this method is easily controllable conditions with
using low cost chromium source is merit to be considered for scaling
up by industrial researchers. Besides we mainly focus on the
catalytic property nano chromium (III) oxide. Oxidation of aromatic
aldehyde/alcohol to the corresponding carboxylic acids can be
performed highly efficiently in the presence of a catalytic amount of
nano chromium (III) oxide in THF as solvent under mild conditions.
