Influence of active acidity of the medium on the stability of MnO2 nanoparticles

In this work, for the first time the results of studying the microstructure of manganese dioxide nanoparticles stabilized with sulfur-containing amino acids are presented. According to the results of scanning electron microscopy, nanoparticles with a diameter of 15-30 nm were presented in the sample...

Active acidity of the medium Spectrophotometry Nanoparticles Manganese dioxide In this work, for the first time the results of studying the microstructure of manganese dioxide nanoparticles stabilized with sulfur-containing amino acids are presented. According to the results of scanning electron microscopy, nanoparticles with a diameter of 15-30 nm were presented in the samples. The optimal mass ratios of precursors were established by means of spectrophotometry, to obtain stable sols of manganese dioxide nanoparticles. The optimal mass ratios were: KMnO4: methionine - 1:1 and KMnO4: cysteine - 3 :1 . Investigation of the effect of the medium active acidity on the stability of manganese dioxide nanoparticles showed that MnO2 samples obtained with methionine are stable at 4 <= pH <= 11, and with cysteine - at 5 <= pH <= 8 2021-01-26T10:16:06Z 2021-01-26T10:16:06Z 2020 Статья Blinov, AV; Maglakelidze, DG; Kravtsov, AA; Blinova, AA; Gvozdenko, AA; Golik, AB; Raffa, VV; Konovalova, EV.
