Embodiment 1

[0029] 10gPt(OH) 4 , 0.5g of hydrazine was dissolved in distilled water respectively, and the two were mixed evenly and stirred, diluted to 1 liter with distilled water, added 2g of ethylenediamine, and 15 drops of 20% EDTA were added dropwise, the solution was heated to 60°C, and the pH was adjusted with NaOH Value to 10, cut the copper mesh into 5×5cm 2 Square shape, put into the solution and let it stand for 30 minutes, take it out, wash it with distilled water, dry it naturally, and obtain the platinum catalyst.

Embodiment 2

[0031] 5.2g RuCl 2 and 5gNaNO 2 Dissolve in a small amount of distilled water respectively, mix well and stir, dilute to 1L with distilled water, add 10 drops of ammonia water dropwise, heat the solution to 45°C, adjust the pH value to 9, and cut the nickel foam into 5×5cm 2 Put the square into the solution and let it stand for 40 minutes, take it out, wash it with distilled water, and dry it naturally to obtain the ruthenium catalyst.

Embodiment 3

[0033] Weigh 2.5g NaOH dissolved in 15mL distilled water, add 3.5gNaBH 4 , and then add the catalyst prepared above, 8.7 liters of hydrogen can be obtained within 6 minutes, and the average rate of hydrogen generation is 1.45 L / min. After the reaction, there are no catalyst particles falling off in the solution. The average hydrogen generation rate of the powdered catalyst by direct reduction is 1.51L / min, which proves that the chemically supported catalyst has good activity.

Abstract

A chemicoplated catalyst for preparing H2 from boron hydride by hydrolysis features that its active component is carried through chemicoplating. Its preparing process includes such steps as preparing chemicoplating solution through dissolving metal salt in distilled water respectively the metal ion contained compound and reducer, mixing, adding additive, regulating pH value and heating, chemicoplating the carrier, washing with distilled water, and drying.

Description

technical field [0001] The invention belongs to the technical field of hydrogen energy catalysis, and in particular relates to a method for hydrolyzing borohydride to produce hydrogen by electroless plating with a supported catalyst. Background technique [0002] In recent years, many scholars at home and abroad have been competing to study the hydrogen production by the hydrolysis reaction of metal borohydrides, and have applied for some patents. The hydrogen production process of borohydride hydrolysis is simple, low cost, high hydrogen yield, and the gas generated by the reaction is pure and contains a small amount of water. Its principle is to dissolve metal borohydride in alkaline solution to facilitate preservation, and add metal Catalysts speed up reactions. Amendola loaded Ru onto IRA-400 cationic resin as a catalyst to catalyze hydrogen production from metal borohydrides. Its preparation is through dissolution, adsorption, exchange and other processes, with tediou...
