Synthesis and characterization of β-MnO2 nanoparticles for hydrogen production

Abstract

The nanoparticles were hydrothermally synthesized using β-MnO2 nanoparticles were primed using a chemical reduction method. β-MnO2 nanoparticles were validated to occur in the type of nanocrystals with a high specific surface area of 109 m2 /g. While β-MnO2 nanoparticles were used as a photocatalyst for wastewater treatment, they demonstrated vastly more efficient hydrogen production action. The greater hydrogen production evaluate (750 mol-1 /h) was attained by separating the artificial sulphide effluent (0.2 M) using β-MnO2 NPs in a photocatalytic reaction. The findings demonstrate the β-MnO2 NPs' efficient power abilities, notably for photocatalytic hydrogen detachment from sulphide wastewater. From this investigation, we evidenced a recyclable tactic for impactful sewage treatment through the use of photocatalytic water splitting employing βMnO2 NPs.
