Preparation of Co3O4 nanostructure morphology by anion-pairing hydrothermal and the effect of gas sensitivity
In this work, Co3O4 materials with different morphologies were synthesized based on cobalt sources containing different anions by hydrothermal method, and the effects of anions on their microscopic morphology and gas sensing properties were explored. The test results showed that the Co3O4 material synthesized with CoCl2 as the precursor had the best comprehensive gas sensing performance, with a high specific surface area of 93.47 m2/g, and a response value of 23.14 to 100 ppm ethanol at 200 °C. Exploring the effect of anions on the properties of Co3O4 materials has a certain guiding effect on the subsequent synthesis of gas-sensitive materials.
期刊介绍:
Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage.
Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
