Hydrothermal synthesis of a bimetallic metal–organic framework (MOF)-derived Co3O4/SnO2 composite as an effective material for ethanol detection

Hydrothermal syntheses were utilized to prepare bis-MOFs derived Co 3 O 4 /SnO 2 composites with small particle size of about 6 nm and a response of 135 to 100 ppm concentration of ethanol. With excellent selectivity, stability, and reproducibility.
