Novel hybrid Co3O4/SnO2 core–shell nanospheres have been effectively realized by a one-step hydrothermal, template-free preparation method. Our strategy involves simple fabrication scheme that entails the coating of natural cross-link agents followed electrostatic interaction between positive charges Sn and Co ions negative charge glutamic acid. The architecture enables novel flexibility gas sensor surfaces compared to commonly used bulk materials. highly efficient transfer unique structure are key ensuring availability high response rapid-response speed. It demonstrates how can be as an advance function material fabricate electrical sensing devices may useful sensors.
