Metal-oxide semiconductor sensing materials with excellent performance are highly desired for the detection of toxic, volatile, and flammable gases. However, lack material structure–property relationships gas-sensing mechanisms has severely limited rational design materials. Herein, we try to understand how electronic structure, d-band center, atomic orbital bonding influence gas adsorption energy, which exhibits a strong correlation both selectivity sensitivity As result, lattice distortion induced by introducing heteroatoms prompts La atoms actively participate in process, leads formation multiatomic hybridization bonds, significantly increasing energy ethanol acetone molecules. This work illustrates that creating greater is an effective strategy modulate strength adsorption, important guiding synthesis metal-oxide
