WebApr 14, 2024 · In this work, the highly active polyoxometalate (PW2Mo2) with Venturello structure and its corresponding catalyst were applied in catalytic desulfurization for the first time. PW2Mo2 as an active component was effectively encapsulated in hollow periodic mesoporous organosilica (HPMOS) to form the nanoreactor PW2Mo2@HPMOS, where … WebElements and Periodic Table History Hydrochloric acid (HCl) was known to the alchemists.
