Technical Field

The invention relates to a catalytic hydrogen production method without metal participation, belonging to new energy.

Background

The search for sustainable, renewable and clean fuel technologies has attracted increasing attention over the last decades. Due to increasing energy consumption and related environmental concerns, solar, wind, and other sustainable energy strategies have become promising alternatives to fossil fuels. However, the daily use of these renewable resources is limited by the efficiency of low energy delivery due to the temporal and spatial intermittency. The conversion of these renewable resources into storable and transportable chemical fuels is a promising approach. In recent years, hydrogen has been considered as one of the most promising chemical fuels, with its advantages of high relative abundance, remarkably high energy density, and zero emission. Hydrogen is just such a new secondary energy source that people expect while the conventional energy crisis appears and new secondary energy sources are developed. As an ideal new energy source of the energy-combining body, the energy-combining body has the following characteristics: the weight is lightest: in the standard state, the density is 0.0899g/L, and when the temperature is 252.7 ℃ below zero, the liquid hydrogen can be changed to metal hydrogen by increasing the pressure to several hundred atmospheres. Generally, hydrogen is mainly generated by industrial steam reforming process, electrocatalytic or photocatalytic water decomposition, electrochemical oxidation crosslinking, catalytic pyrolysis or hydrolyzed hydrogen storage materials (including hydrogen-rich inorganic hydrides, metal hydrides and the like), but the key is to find a catalyst with high efficiency, good stability and no pollution, and a catalytic method without metal participation is invented. Alkaline solution is used as a catalyst to catalyze the hydrolysis of tetrahydroxy diboron to produce hydrogen, and the method is green and environment-friendly and has good effect.

From the literature reports, the report of hydrogen production catalyzed by metal-free alkali solution has not appeared. Therefore, the method has incomparable effects, such as environmental protection, no pollution and high yield.
