Abstract: | We have designed and successfully synthesized innovative Pt and Co3O4 nanostructure co-decorated In2O3 nano-branches via stepwise facile chemical approaches for room-temperature CO gas sensing. The present results indicate that the combination of well-dispersed tiny Pt nanoparticles and the secondary oxide, p-type Co3O4, nanostructures with optimized fractions onto the n-type In2O3 nano-branches is an effective strategy which could lead to lowering the operating temperature to room temperature and significantly improving the sensitivity as well as the detection limit to a sub-ppm level, for meeting the requirement of advanced gas sensors for the next generation. |
