Facile size-controllable synthesis of single crystalline \b{eta}-MnO2 nanorods under varying acidic strengths
Niraj Kumar, P. Dineshkumar, R. Rameshbabu +1
A simple one-pot hydrothermal synthesis of single crystalline beta-MnO2 nanorods with diameters in the range of 10-40nm is reported. During the synthesis process, the acid molariti…
Morphological analysis of ultra fine α-MnO2 nanowires under different reaction conditions
Niraj Kumar, P. Dineshkumar, R. Rameshbabu +1
A simple hydrothermal method was developed for the synthesis of ultra fine single-crystal α-MnO2 nanowires by only using potassium permanganate and sodium nitrite in acidic solutio…
Enhanced pseudocapacitance from finely ordered pristine alpha-MnO2 nanorods at favourably high current density using redox additive
Niraj Kumar, K. Guru Prasad, Arijit Sen +1
A flexible technique is developed using hydrochloric acid to modify the redox reaction between potassium permanganate and sodium nitrite in order to grow ultrafine alpha-MnO2 nanor…
Facile synthesis of 2D graphene oxide sheet enveloping ultrafine 1D LiMn2O4 as interconnected framework to enhance cathodic property for Li-ion battery
Niraj Kumar, Jassiel R. Rodriguez, Vilas G. Pol +1
Cubic spinel lithium manganese oxide (LiMn2O4) has been able to attract a great deal of attention over the years as a promising cathode material for large scale lithium ion batteri…
Precise control on morphology of ultrafine LiMn2O4 nanorods as supercapacitor electrode via two-step hydrothermal method
Niraj Kumar, K. Guru Prasad, T. Maiyalagan +1
We report three different synthesis routes while maintaining similar reaction conditions to choose an effective way to precisely control the growth of ultrafine one dimensional LiM…
