Получен нанокомпозит серебра на матрице природного полисахарида – гуаровой камеди, сшитой боратными мостиками. Металлические наночастицы получены восстановлением ионов серебра под действием полисахарида. Образование нанокомпозитов подтверждено методами УФ-, ИК-спектроскопии и рентгеновской дифракции. Полученный полимерный нанокомпозит проявляет каталитическую активность в реакции восстановления 4-нитрофенола боргидридом натрия в мягких условиях.
