Three-Dimensional Ordered Mesoporous MnO2 …

2019-5-25 · Three-dimensional (3D) ordered mesoporous Ag/MnO2 catalyst was prepared by impregnation method based on 3D-MnO2 and used for catalytic oxidation of HCHO. Ag nanoparticles are uniformly distributed on the polycrystalline wall of 3D-MnO2. The addition of Ag does not change the 3D ordered mesoporous structure of the Ag/MnO2, but does reduce the pore size and surface area. Ag …

A MnO2 Nanoparticle-Dotted Hydrogel Promotes …

2020-5-7 · Spinal cord injury (SCI) is one of the most debilitating injuries, and transplantation of stem cells in a scaffold is a promising strategy for treatment. However, stem cell treatment of SCI has been severely impaired by the increased generation of reactive oxygen species in the lesion microenvironment, which can lead to a high level of stem cell death and dysfunction. Herein, a MnO2 ...

Removal of uranium using MnO2/orange peel biochar ...

2020-11-1 · Orange peel is an important resource in view of its low-cost and universal nature. A novel material (MnO 2 /orange peel carbon, MnO 2 /OPC) was yielded via a single step involving activation and in situ deposit. The feasibility of uranium removal using MnO 2 /OPC was tested by varying MnO 2 loading amount, pH, ionic strength, uranium initial concentration and temperature. 1.2MnO 2 /OPC …

Fe3O4/PANI/MnO2 core–shell hybrids as advanced …

Multifunctional magnetic adsorbents containing MnO2 and polyaniline (PANI) with optimized adsorption properties toward heavy metal ions have been developed. In particular, Fe3O4 spheres were chosen as the magnetic core, followed by PANI and MnO2 coating, realizing the formation of Fe3O4/PANI/MnO2 …

Unique MOF-derived hierarchical MnO2 …

Nanostructure is the most important aspect in the development of high performance supercapacitors. In this work, we designed and developed new one-dimensional hierarchical hollow nickel–cobalt layered double hydroxide nanocages assembled on MnO2 nanotubes with uniformly dispersed CoS2 nanoparticles, MnO2@NiC
