Development of Mn ions incorporated tin oxide nanostructures for effective photocatalytic degradation of toxic dyes and enhanced supercapacitor applications
To improve energy storage and photocatalytic (PC) activity for the removal of organic pollutants, we synthesize pure and Mn-doped stannic oxide at different concentrations in this work. The physicochemical parameters of the synthesized materials were investigated employing a variety of analytical instruments. Here, we synthesize the samples using a simple hydrothermal approach. At 5 A/g current density, a maximum specific capacitance of 325 F/g was demonstrated by a Mn-doped stannic oxide electrode. After 1000 continuous cycles of charging and discharging, 84.83% retention of capacitance was noted. Additionally, when Mn-doped stannic oxide NPs are utilized as a photocatalyst to reduce brilliant green (BG), alizarin red S (AR S), and methyl orange (MO) dyes in the presence of sunlight, methyl orange shows the highest degradation efficiency of 96% when compared to all other dyes.
