AgNO_3水溶液中Ag(Ⅰ)的紫外光和可见光光致还原的速度较慢,WO_3半导体催化剂能加快Ag(Ⅰ)的光致还原,并且加入甲醇空穴捕捉剂后可显著提高Ag(Ⅰ)的光致还原率。AgNO_3溶液的浓度和酸度(pH=2～7)以及催化剂用量等均对Ag(Ⅰ)的光致还原率有一定的影响。
The photocatalytic activity of Ag (Ⅰ) in AgNO_3 aqueous solution was slower than that of Ag (Ⅰ) in photocatalytic reduction of Ag (Ⅰ). Photocatalytic reduction of Ag (Ⅰ) by WO_3 semiconductor catalyst accelerated the photocatalytic activity of Ag Photoreduction rate. AgNO_3 solution concentration and acidity (pH = 2 ~ 7) and the amount of catalyst and so on Ag (Ⅰ) have a certain impact on the photoreduction rate.
