Potassium-modulated δ-MnO2 as robust catalysts for formaldehyde oxidation at room temperature
Article
  • Sep 2019
Engineering MnO2 with rich surface active oxygen species is critical to effectively eliminate formaldehyde (HCHO) under mild conditions. Herein, we introduced a facile redox method to fabricate a series of δ-MnO2 samples by varying the concentration of K⁺, which efficiently modulated the layer size, morphology, crystallinity, redox properties, and...

... Based on the analysis of the catalytic mechanism, the key step of ozone decomposition is the discharge desorption of charged oxygen groups, and the main difficulty in this step is that the material needs to have the ability to capture electrons [52]. According to this viewpoint, Ma et al. [51] proposed a method of partially oxidizing the Cu2O surface to produce CuO heterojunctions to improve catalytic efficiency. ...
