Characterizations of 12-tungstophosporic acid metal salt nano particles synthesized by ultrasound

Abstract

A set of nano metal exchanged 12-tungtophosphoric acid salt (M =Fe, Cr, Ni, Cu) was synthesized under ultrasonic irradiation in nanoscale. To thoroughly recognize the structure transformation induced by metal doping and morphologies of as-prepared M-TPA catalysts, a combination of XRF, XRD, SEM-EDX, N2 adsorption-BET, were employed. These analyzes indicate that the chemical structure and crystallinity of nano M-TPA's remained unchanged while its morphology was found a different particle size according to the exchange metal.

Ultrason yardımı ile sentezlenen 12-tungstofosforik asit metal tuzu nanoparçacıklarının karakterizasyonları

Öz

Bir dizi nano metal değişimli 12-tungtofosforik asit tuzu (M =Fe, Cr, Ni, Cu) ultrasonik ışınlama altında nano ölçekte sentezlenmiştir. M-TPA katalizörlerinin metal dopingi ve morfolojilerinin neden olduğu yapı dönüşümünü tam olarak tanımak için XRF, XRD, SEM-EDX, N2 adsorpsiyon-BET kombinasyonu ile karakterizasyon yapılmıştır. Bu analizler, nano M-TPA'nın kimyasal yapısının ve kristalliğinin değişmeden kaldığını, morfolojisinin metale göre farklı bir partikül boyutu bulunduğunu göstermektedir.
