The humidity sensitive property of MgO SBA 15 composites in one pot synthesis

MgO-SBA-15 has been successfully developed as a kind of humidity-sensitive material. The structure of MgO-SBA-15 materials was characterized by XRD, IR spectroscopy, N2 adsorption–desorption, TEM and XPS. The study proved that the MgO did not destroy the mesoporous structure of SBA-15 via the characteristic results of XRD and N2 adsorption–desorption. Researchers built the thick film humidity sensors on the Al2O3 ceramic substrate with two Ag–Pd interdig
