Nghiên cứu chế tạo tinh thể nano kim loại đồng bằng phương pháp hoàn nguyên ở nhiệt độ thấp nhằm ứng dụng trong nông nghiệp

Abstract

Copper nanoparticles were prepared by hydrogen reduction by electrolysis of water. The formation, structure and morphology of products were characterized by X-ray diffraction analysis (XRD), Scanning Electron Microscope (SEM) and the specific surface area (BET) was determined by N₂ physisorption Brunauer - Emmitt - Teller (BET) method. The results showed that copper particles are a simple phase and the size about 40-70 nm, the BET-surface area as 15.85 m²/g. The data showed that copper nanoparticles increased germination rate of maize at normal condition.

Keywords: Copper nanoparticles, reverting method.
