Chinese companies have successfully produced metal nanomaterials below 10 nanometers

Through cooperation with domestic research institutes, Chinese companies have created a process oxidation method in the world after several years of trial and error and technological breakthroughs. They have taken the lead in the international production of metal nanomaterials below 10 nanometers, which has caused international industry. highly anticipated. The Chinese company independently researched and developed the photocatalytic net like 'fishing net' with graphene-doped metal nano-titanium dioxide material below 10 nanometers. It has been applied to the domestic black-smelting river water treatment this year.

As we know, superparamagnetic nanomaterials below 10 nanometers are an advanced material that is urgently needed in modern medicine, pharmacy, biotechnology and military equipment. However, to achieve mass production of metal nanomaterials below 10 nanometers, the technical difficulty is very high. In the past 10 years, although domestic research institutions have invested in human and financial resources, they have been stuck in the laboratory stage because of the difficulty in research and development. "Currently used centrifugal separation method to screen metal nanomaterials below 10 nanometers is rough, difficult to industrialize, and it is difficult to guarantee accuracy. I have also made it in the laboratory." Dr. Xiu Xiuxi, Pharmaceutical and Environmental Engineering, Changzhou Engineering Vocational and Technical College I told reporters that at present, there are production and application problems in the preparation methods of metal materials below 10 nanometers in the world, such as long production cycle, high cost, difficult to guarantee purity, and troublesome post-processing of products.

“Three years ago, we aimed at this global hot spot in materials science and chemistry research, formed a research team with multidisciplinary international experts, and implemented key research projects around the needs of modern medicine and emerging industries, and experienced countless failures. Thousands of repetitive experiments, we finally found a new preparation technology, the world's first ionic liquid anode electro-peeling process oxidation method, successfully produced metal nanomaterials below 10 nanometers." Superparamagnetic below 10 nanometers Nanomaterials have broad application prospects. Among them, the use of the prepared metal nano-titanium dioxide material below 10 nanometers can be applied to the environmental protection field for the treatment of black and odorous river channels. “We have used a photocatalytic net like 'fishing net' made of graphene-doped metal nano-titanium dioxide material below 10 nanometers, which has been applied to black odor river water treatment in Xi'an and Guangzhou. The photocatalytic network is placed in water. As long as there is visible light, it can help break down the organic matter in the water and restore the water body to self-cleaning ability. In addition, the graphene-based photocatalytic air purification material can effectively remove indoor formaldehyde and other harmful substances as curtains, and has been tested by experts. It has obvious effect on removing formaldehyde in the room. According to experts, after repeated trials and technological breakthroughs, Chinese companies have made the world's original “application process oxidation method”, which is not only low in cost, large in volume, but more important in purity. The developer made of the metal nano-materials of less than 10 nanometers has a small particle size, which is not only clear in development but also less harmful to the human body; at the same time, because it also has superparamagnetism, it can be targeted with drugs. The carrier of the drug. This medical developer is being tested in pilot hospitals, and the next step will be to promote the application to more hospitals and pharmaceutical companies.
