Bimetallic MOFs-Derived Metal Oxides CoO/SnO Microspheres for Ultrahigh Response -Butanol Gas Sensors.

The construction of p-n heterojunctions is expected to be one of the effective means to improve gas sensitivity. In this research, p-n heterojunctions are successfully constructed by metal oxides derived from metal-organic frameworks (MOFs). MOFs-derived bimetallic CoO/SnO microspheres are prepared by precipitation.

New Analysis Method for Adsorption in Gas (H, CO)-Solid (SnO) Systems Based on Gas Sensing.

The chemisorption phenomenon is widely used in the explanation of catalysis, gas-solid reactions, and gas sensing mechanisms. Generally, some properties of adsorbents, such as adsorption sites and dispersion, can be predicted by traditional methods through the variation of the chemisorption capacity with the temperature, pressure, and gas-solid interaction potential. However, these methods could not capture the information of the interaction between adsorbents, the adsorption rate, and the competitive adsorption relationship between adsorbents.
