MCM-41 molecular sieves with high structural stability and long-range order were synthesized using ethylamine (EA) as an additive instead of mineralizers such as NaOH and TPAOH. X-ray diffraction showed that the EA/CTAB (cetyltrimethylammonium bromide) ratio was the critical factor that determines t...
