A thermal and hydrothermal stable mesoporous ceramic acid (mCA) was synthesized by uniform coating of a WZrOx layer onto the internal surface of extra-large mesoporous silica (EP-FDU-12). Its ordered mesoporous structure and strong Bronsted acid sites display excellent thermal (1000 degrees C, air, 5 h) and hydrothermal (water steam, 300 degrees C, 24 h) stability.
