The prepared catalysts were thoroughly characterized by various physico-chemical methods. TEM images showed uniform dispersion of MoO3 nanoparticles (1.5-4 nm) onto silica (similar to 275 nm). No separate MoO3 particles were identified from TEM for MoO3/TiO2 (similar to 10.5 nm) and MoO3/ZrO2 (similar to 6.5 nm) because AHM reacted with titanium and zirconium hydroxides to form solid solution. Among the prepared catalysts MoO3/SiO2 showed excellent catalytic activity (up to 90% conversion and 100% epoxide selectivity) for olefin epoxidation. The catalyst was successfully recycled up to five cycles without losing much activity and selectivity.</p>1 aChandra, Prakash1 aDoke, Dhananjay, S.1 aUmbarkar, Shubhangi, B.1 aBiradar, Ankush, V.  uhttps://library.ncl.res.in/content/one-pot-synthesis-ultrasmall-moo3-nanoparticles-supported-sio2-tio2-and-zro2-nanospheres-0
