水参与制氢的cu-p体系研究
, PP. 507-512
Keywords: 制氢,cu-p体系,水,绿色化过程
Abstract:
？研究了水参与的cu-p氧化还原体系制氢过程。考察了cu/p物质的量比、反应温度、酸度、外加cu单质等对氢气产率的影响，设计了cu的循环利用和p的转化利用过程，实现了cu-p体系的绿色化过程。结果表明，通过调控cu/p物质的量比和反应温度等因素可以控制反应过程中生成的氢原子转化为氢气的量，在以0.20g五水硫酸铜为基准物的cu2+/h2po2-物质的量比为0.05和95℃反应条件下可获得大于反应计量比的18.6ml氢气；酸性条件下h2o2氧化单质cu可以实现cu的10次循环利用；制氢过程生成的亚磷酸氢根可以用ca（oh）2处理转化为新型防锈剂cahpo3·h2o，该防锈剂用红外光谱（ft-ir）和x射线衍射（xrd）得到了表征。
