Alpha Manganese Dioxide Nanowire Nano MnO2 Wire

Manganese dioxide (MnO₂) nanowires are one-dimensional nanostructures prized for their unique physicochemical traits. Their defining feature is the crystalline α-phase with a 2×2 tunnel structure, which acts as efficient ion highways, enabling rapid insertion/extraction of Li⁺, Na⁺, Zn²⁺, and protons.

Alpha Manganese Dioxide Nanowire Nano MnO2 Wire


Specification of MnO2 nanopowder:

Phase: alpha, beta also available

Diameter: <100nm

Length: 1-10um


Application of manganese dioxide nanowires: 

1. Energy storage and conversion: This is its most popular application. As an electrode for supercapacitors, it has a very high theoretical specific capacitance (up to 1370 F/g). As the negative electrode of lithium batteries, its initial discharge capacity can reach 1373 mAh/g. In addition, it has also been studied for use as a counter electrode in dye-sensitized solar cells and for aqueous energy storage devices such as zinc-ion batteries.

2. Catalysis and Environmental Protection: It is an excellent catalyst. For instance, when used in sewage treatment, it can effectively degrade organic dyes (such as rodocaine B and Congo red) in the Fenton reaction. It can also selectively oxidize HMF to DFF in biomass conversion.

3. Optics and Sensing: Research shows that it has excellent nonlinear optical absorption performance and can be used in optical limiters (to protect sensors from strong light damage). At the same time, based on its surface reaction, it can also be used to make sensors for detecting hydrogen peroxide or ascorbic acid.

Silicon nano technology reforming graphite cathode lithium batteries

Silicon nano technology reforming graphite cathode lithium batteries       Cathode technology of the existing lithium batteries has reached the limit. In order to meet the needs of a new generation of energy, the development of new cathode technology of lithium batteries is imminent. Silicon cathode, with the ultra-high specific capacity and rich reserves, has become one of the most representative new technology.     Compared to the traditional graphite cathode, a major obstacle to the Silicon cathode technology on the road of industrialization is that low gel content cause unsatisfactory effect of electrode mixing.     On account of this, some researchers integrated graphite cathode technology and Silicon nano technology and have developed a new and can be mass-produced C- nano Si- graphite composite cathode materials. During the lithiation process, Si nanoshells can be expanded as the volume change. No matter nano-Si hollow shell in the graphite , or a nano-Si intermediate layer between the graphite and carbon, it can keep the shape intact and not be broken or left over between Si and graphite. This special structure, on the one hand to ensure compatibility between the Si and natural graphite, on the other hand avoid the severe side effects caused by traditional mechanical mixing graphite powder and residual Silicon particles.     Silicon Nano Powder is generally immediately available here with particle size 30-50nm,100-200nm,300-500nm,1um. Chinese Hongwu International Group LTD with HW NANO brand can produce most materials in high purity forms and ultrafine particle size. We can also produce materials to custom specifications by request, in addition to custom compositions for commercial and research applications and new proprietary technologies. Typical and custom packaging is available, can provide related data including SEM,TEM,COA,MSDS.
