Summary: In this study, SnO2-Pd nanoparticles were synthesized using an in situ synthesis-loading method. The nanoparticles exhibited a tetragonal structure with a size smaller than 10 nm and a uniformly distributed Pd catalyst in the SnO2 lattice. A gas sensitive thick film with a thickness of about 40 μm was successfully fabricated using these nanoparticles. Characterization of the film's gas sensing properties showed that the gas sensitivity was enhanced to 0.59 after heat-treating the SnO2-Pd nanoparticles synthesized with the in situ method at 500 degrees C. Therefore, the in situ synthesis-loading method is a viable approach for the synthesis of SnO2-Pd nanoparticles for gas sensitive thick film.

Summary: We report an environmentally friendly method for preparing flexible self-supporting membrane electrodes based on reduced graphene oxide (rGO), in which Co-MOF is combined with graphene oxide to quickly prepare a hollow CoO@rGO composite with a porous structure. The unique hollow porous structure shortens ion transport paths and provides more active sites for lithium ions. The high conductivity of rGO facilitates rapid charge transfer and offers buffer space for the hollow Co-MOF nanocubes during charging. The resulting CoO@rGO flexible electrode demonstrates good rate capability and cycling stability, maintaining a high specific capacity of 1103 mAh g(-1) after 600 cycles at 1.0 A g(-1). The high capacity is attributed to the synergistic effect of the hollow porous structure and the 3D reduced graphene oxide network. This represents a promising new strategy for synthesizing hollow porous-structured rGO-based self-supported flexible electrodes.
