Abstract

original image

Mehr als ein Metall enthalten die mesoporösen Materialien MGa2O4 (M=Zn, Ni, Co), die durch Ionenaustausch aus kolloidalem mesoporösem NaGaO2 zugänglich sind (siehe Schema mit TEM-Bildern). Weil diese Vorstufe zugleich als Templat wirkt, spart man einen Templatentfernungsschritt ein.
