A method for synthesizing hydrogen peroxide using metal-organic framework materials and its application in green catalytic synthesis.

Abstract

This invention discloses a one-step method for synthesizing metal-organic framework materials encapsulating high atomic number oxides and its application in the green catalytic synthesis of hydrogen peroxide using high-energy radiation. This invention utilizes high atomic number-doped metal-organic framework materials as catalysts, dispersing them in water while maintaining an oxygen atmosphere. Hydrogen peroxide is then obtained using high-energy radiation such as X-rays, gamma rays, alpha rays, and electron accelerators. This method is simple; compared to the industrial anthraquinone method, it does not require large-scale equipment and is pollution-free; compared to electrocatalysis, it does not require the addition of electrolytes; compared to direct hydrogen-oxygen synthesis, it does not require mixing hydrogen and oxygen, eliminating the risk of explosion; and compared to photocatalysts, it does not require additional sacrificial agents. Hydrogen peroxide can be synthesized in pure water, which facilitates subsequent separation and collection. This invention enables the synthesis of H2O2 in pure water, possessing significant economic value and broad application potential.

Description

Technical Field

[0001] This invention relates to a method for preparing hydrogen peroxide, specifically a method for preparing hydrogen peroxide using a catalyst under high-energy radiation conditions. Background Technology

[0002] Since modern times, the energy industry has developed rapidly and has become one of the lifelines of the national economy. However, soaring global energy prices and a sweeping energy crisis have yet to be fully resolved. Currently, the global energy landscape is undergoing profound adjustments, with traditional fossil fuels gradually being replaced by clean, low-carbon energy sources. Nuclear energy can play a vital role in building a modern energy system, protecting the ecological environment, addressing climate change, promoting scientific and technological progress, enhancing national comprehensive strength, and ensuring energy security. Currently developed new and renewable energy sources, such as solar, wind, and ocean energy, are limited by geographical location and seasonal conditions, hindering their large-scale construction and utilization. Nuclear energy, due to its extremely high energy density; the fact that nuclear power generation does not produce harmful gases such as sulfur dioxide and does not pollute the air; the fact that, for the same power output, nuclear power consumes far less nuclear fuel than a coal-fired power plant of the same capacity; and the significant advantages of nuclear power generation in terms of land area and energy supply security compared to renewable energy sources such as wind and solar power. From both an economic and environmental perspective, nuclear energy is considered a promising alternative to traditional energy sources.

[0003] Traditional H2O2 synthesis primarily relies on the oxidation of anthraquinone (AQ), a process that requires significant fossil fuel energy input and generates hazardous waste. High demand is driving researchers to develop alternative, sustainable pathways for H2O2 production. Photocatalytic photochemical synthesis of H2O2, limited by factors such as light sources, often cannot be mass-produced, remaining confined to laboratory levels for a long time, severely hindering its industrial application, and its economic feasibility is also highly controversial.

[0004] The high-energy rays or particles (gamma rays, electron beams, protons, etc.) in nuclear energy carry energies far exceeding molecular bond energies, theoretically capable of realizing the formation of any molecule in nature. Furthermore, they are widely used in the medical and nuclear industries and have mature practical applications. High-energy ray catalytic preparation of hydrogen peroxide offers advantages such as low-cost reaction substrates and rapid resource recovery from O2 with minimal catalyst usage, leading to the rapid synthesis of hydrogen peroxide. With the promotion of industrial and medical accelerators in my country, this technology has broad industrialization prospects, providing a new, green, and feasible solution for the sustainable generation of H2O2.
