Abstract

The photochemical reduction of water with cadmium sulfide suspensions containing mixtures of sodium sulfite and formic and acetic acid solutions has been studied by electromotive force measurements and gasometry. The sulfite ions are oxidized on the anode in the sulfite–acetate suspensions; the sulfite ions and formic acid, in the sulfite–formate solutions. Hydrogen peroxide was found among the products of the photochemical reaction; it is involved in the oxidation of the radicals of sulfite ions and molecular sulfur of CdS particles and prevents the reduction of water.

添加亚硫酸钠、甲酸和乙酸的混合物对硫化镉悬浮液光催化还原水的影响

摘要

通过电动势测量和气量测定法研究了含有亚硫酸钠、甲酸和乙酸溶液的混合物的硫化镉悬浮液对水的光化学还原。亚硫酸盐离子在亚硫酸盐-乙酸盐悬浮液中的阳极上被氧化；亚硫酸盐-甲酸盐溶液中的亚硫酸根离子和甲酸。光化学反应的产物中发现了过氧化氢；它参与亚硫酸根离子自由基和CdS颗粒分子硫的氧化，并阻止水的还原。
