Summary: Due to the rapid development of information and electronic technologies, there is an urgent need to design and prepare new materials with electromagnetic interference (EMI) shielding function to reduce electromagnetic pollution. In this study, a thin magnetic Ti3C2Tx MXene (MMX) nanocomposite film was successfully obtained by combining Ti3C2Tx MXene nanosheets with porous magnetic microspheres (PMMs), exhibiting excellent EMI shielding performance. The lamellar structure of Ti3C2Tx MXene nanosheets provides flexibility to the MMX nanocomposite film, while PMMs enhance the attenuation ability of the film to electromagnetic wave energy. The rough surface of PMMs improves electromagnetic wave consumption and enhances the performance of Ti3C2Tx MXene EMI shielding nanocomposites.

Summary: A series of Co(OH)(x)(A)(y) materials with different acidic anions were synthesized and their catalytic activity for the OER was determined. Surface oxidation and the content of highly active Co(IV) were found to be crucial parameters for the OER performance. Furthermore, the leaching ability of anions in Co(OH)(x)(A)(y) was directly related to the Co(IV) content and the catalytic activity, which can be summarized as an anion leaching-metal oxidation model. This study provides deep insights into the anion effect of metal basic salt-based OER catalysts and the activation process of pre-catalysts for the OER.
