Tin (IV) oxide-supported Pd is a promising heterogenous catalyst for CO oxidation relevant for environmental cleanup reactions. In this study, atomically dispersed catalyst Pd on SnO2 (ADC Pd/SnO2) hybrid material is successfully synthesized via a straightforward wet chemistry method and is found to exhibit superior performance toward CO sensing. Ex-situ EXAFS analysis confirms the formation of single Pd atoms and small Pd nanoclusters stabilized on the SnO2(110) surface. The material exhibits high efficiency in generating adsorbed O2– as well as high activity in catalyzing CO oxidation at...

Metal oxide semiconductors (MOX) such as SnO2 are widely used in chemiresistive gas sensors due to their high chemical and thermal stability, low cost, and tunable chemical and electronic properties. The introduction of porosity to the MOX structure enhances their gas-sensing properties by increasing the surface area available for interactions with gas molecules. This higher surface area enhances the sensor's sensitivity by providing more active sites for gas adsorption. Also, a faster response/recovery time can be obtained as gas molecules can more quickly interact with a...

Atomically dispersed metal catalysts have garnered considerable attention due to their unique properties and superior catalytic activity. The isolation of metal atoms on the matrix offers enhanced catalytic performance even with a small content of noble metal loading. This class of materials provides exciting opportunities to improve the performance of chemical and biochemical sensors. In this work, we have selected Pd as the catalysts because of its high catalytic activity and graphene oxide as the matrix because of its high electrical conductivity and unique electrochemical properties....
