Mesoporous W-MCM-22 molecular sieves were prepared for the first time by directly hydrothermal synthesis using silica gel as the source of silicon, sodium tungstate as the tungsten source, piperidine as a structure-directing agent (SDA) and boric acid as a structure-supporting agent under dynamic state.
