This paper reviews several important preparation methods, and several kinds of MnO 2
composites, which is efficient in formaldehyde catalytic oxidation. The preparation of MnO 2 …

The transformation of graphitic carbon nitride (g-C3N4) from nanoplates to nanorods was
realized by a simple reflux method. The photocatalytic activity and the intensity of the …

The traditional scheme of metals extraction from minerals involves some processes of
mechanical character ameliorating the accesibility of the valuable component by the …

Abstract α‐, β‐, γ‐, and δ‐MnO2 single‐crystal nanowires/nanorods with different aspect
ratios have been successfully prepared by a common hydrothermal method based on the …

In this paper, MnO2 nanomaterials of different crystallographic types and crystal
morphologies have been selectively synthesized via a facile hydrothermal route and …

A cathode material for rechargeable lithium batteries is one possible application for the
birnessite‐related layered MnO2 nanobelts (see Figure) reported here. A simple …

Inorganic nanomaterials are widely used in heterogenous catalysis. With the development of
nanoscience and nanotechnology, chemists can precisely control the size, morphology, and …

Single-crystalline α-MnO2 nanorods have been prepared by reducing KMnO4 with graphite
in concentrated H2SO4 solution at 0° C. Hydrothermal treatment of the α-MnO2 nanorods at …

Understanding and controlling the polymorphism of manganese dioxide (MnO2) is of vital
importance in many nanoscale applications. Here in situ powder X-ray diffraction (PXRD) in …

Bi2O3 catalysts have been prepared via precipitation method by using Bi (NO3) 3· 5H2O as
a starting material and NaOH as the precipitating agent. The influence of bismuth …
