Abstract
Silver crystals electrodeposited from AgNO3 (8%) and Pd2+ (250 mg/dm3) electrolyte before and after exposing to the conditions of the methanol to formaldehyde oxidation process were investigated by AES. Carbon, sulfur, oxygen and palladium on the surface were observed. Higher Pd concentration on the silver surface than in the bulk was found. Its amount on the surface decreased with the temperature increase.
Abstract
Исследовали кристаллы серебра, электролитически высаж-денные из электролита, содержащего AgNO3 (8%) и Pd+2 (250 мг/л), перед и после кондиционирования в условиях процесса окисления метанола до формальдегида с помощь AES. На поверхности детектировали углерод, серу, кисло-род и палладий. Найдено, что на поверхности концентра-ция Pd выше, чем в массе, и с увеличением температуры уменьшается.
