摘要
以循环流动的盐酸和硫酸水溶液为电解质 ,在燃料电池反应器中进行了过氧化氢和电能共生的研究。结果表明 ,石墨可作为共生的适宜催化剂 ,生成过氧化氢的电流效率可达 42 %。氧气分压是影响反应速率的主要因素 ,p H值对反应速率影响小 ,但对生成过氧化氢的电流效率影响大 ,特别是当 p H<1时 ,随 p H值减小 ,电流效率明显下降。
Study on cogeneration of electricity and hydrogen peroxide was conducted in a fuel cell reactor, while HCl aqueous solution or H 2SO4 aqueous solution was used as electrolyte. Results indicated that graphite is a suitable catalyst for the cogeneration, and current efficiency can be up to 42%. The partial pressure of oxygen was the main factor for the reaction, which affects the reduction rate of oxygen on the cathode, pH has little effect on the reaction rate. However, the effect of pH on the current efficiency was obvious, especially when pH<1.
