Effect of Charged Conditions of Stabilizers for Cadmium Sulfide Microcrystalline Photocatalysts on Photoreduction of Carbon Dioxide

Abstract
The use of stabilizers having negative charges such as polyacrylic acid for CdS microcrystals in aqueous solutions yielded selectively formate as a photoreduction product of CO2, while positively charged stabilizers such as polyethyleneimine worked well for selective production of CO. Furthermore, it was found that the rate of photo-induced reduction of carbon dioxide was influenced by the amount of charges of the stabilizers used.
