Bacteriostatic Catalytic Reduction Porous Material and Its Preparation and Application in Production of Reduced Water

Abstract

The invention belongs to the technical field of novel materials, and relates to an antibacterial catalytic reduction porous material and a preparation method thereof, as well as application of the antibacterial catalytic reduction porous material in production of reducing water. The antibacterial catalytic reduction porous material is a catalytic material prepared by performing processes of dipping, calcining, in-situ catalytic reduction deposition, in-situ photoreduction deposition and the like by taking a porous material serving as a carrier, metal iron, cerium and palladium serving as catalytic reduction active components and nano silver serving as an antibacterial component; the palladium and the silver are carried at positions, such as the pore walls and the outer layer of the porous carrier, which are in full contact with aqueous vapor, in a uniform dispersing manner, so that the catalytic reduction effect is exerted to the maximum extent, and the antibacterial effect is guaranteed. According to the antibacterial catalytic reduction porous material, the contradiction between the antibacterial activity and the reduction performance of the reducing water is solved; under a common filling (relative to germfree filling) condition, antibacterial freshness retaining is realized, a reducing water production process is simplified, and the cost is reduced. The material and a device work under a strong reduction performance condition, and the silver mainly exists in an elemental form, so that loss is low, and the service life is long; meanwhile, no excessive silver ions are introduced into the water, and the safety is high.

Description

technical field [0001] The invention belongs to the technical field of new materials, and relates to a bacteriostatic catalytic reduction porous material, a preparation method thereof and an application in producing reduced water. Background technique [0002] Water is the source of life, and the quality of water determines the quality of human life and plays a decisive role in human health. With the improvement of living standards, people pay more and more attention to healthy drinking water, and obtaining healthier water has become an urgent need. Since Professor Ohsawa of Japan discovered in 2007 that hydrogen can selectively scavenge malignant free radicals in the human body and produce antioxidant effects, the prevention and treatment of hydrogen-rich water on human chronic diseases has become a research hotspot. The role of hydrogen in diabetes, cardiovascular and cerebrovascular diseases , cancer prevention and treatment, and reports on beauty and anti-aging have eme...

Problems solved by technology

The hydrogen-rich magnesium rod method and the electrolysis method require a heating device and an electrolysis device respectively, which are only suitable for household or fixed-point use, and are inconvenient to carry. The water produced cannot be stored for a long time, and can only be prepared and drunk immediately

Not only that, the above two methods generally increase the hardness of the water, which affects the taste and is not suitable for some people (such as: patients with kidney stones and gallstones)

The gas-liquid mixing method also has its own problems. Because pure water and mineral water generally need ozone sterilization before filling, and then fill and seal in the state of residual ozone, if hydrogen is introduced into the water before ozone sterilization, it will cause damage to the water. Most of the hydrogen overflows during sterilization and loses its reducing effect. If active hydrogen is introduced after ozone sterilization, it will be difficult to guarantee the antibacterial effect of the product, and its storability and safety will be problematic

In addition, the gas-liquid mixing method takes a long time to produce hydrogen-rich water, and the reduction activity of water is also low, because the solubility of hydrogen in water is very low, it is difficult to reach an effective concentration, and the reduction activity of non-new ecological hydrogen molecules is not high. The tourmaline cup uses tourmaline and germanium placed in the cup to react weakly with water to generate a small amount of hydrogen molecules to produce reducibility. The disadvantage is that the amount of hydrogen generated is small, and the reducibility of water is weak. It can reach about -100mV, and it cannot play a good role in removing harmful oxidative substances in the human body.
