inorganic–organic nanohybrid material SBA-15@triazine/H5PW10V2O40 (SBA-15@ADMPT/H5PW10V2O40) was prepared and used as an efficient, eco-friendly, and highly recyclable catalyst for the one-pot multicomponent synthesis of multisubstituted pyridines from the reaction of aldehydes, cyclic ketones, malononitrile, and ammonium acetate with good to excellent yields (77–97%). The nanohybrid catalyst was prepared by the chemical
