Synthesis of Hydronium-Potassium Jarosites: The Effect of pH and Aging Time on Their Structural, Morphological, and Electrical Properties

Structural and morphological properties of hydronium-potassium jarosite microstructures were investigated in this work, their electrical evaluated. All the synthesized at a very low temperature 70 °C with reduced reaction time 3 h. An increase pH from 0.8 to 2.1 decreased particle sizes µm 200 nm an aging zero, three, seven days resulted semispherical, spherical, euhedral structures, respectively. The Rietveld analysis also confirmed that amount hydronium substitution by potassium cationic site increased pH. percentages (JH)/potassium (JK) for values 0.8, 1.1, 77.72/22.29%, 82.44/17.56%, 89.98/10.02%, Microstructures obtained work tested as alternative anode materials voltage measured using these electrodes made graphite ranged 0.89 1.36 V. results show size morphology obtained, modified can be used improving lifetime lithium-ion batteries.
