synthesis and investigation of fe@mn_n-c electrocatalyst for oxygen reduction reaction in fuel cell

Since the indiscriminate exploitation and consumption of fossil fuels has caused severe global energy crisis and environmental damage, it is necessary to further develop renewable and sustainable energy conversion and storage devices. poor electrical conductivity and unfavorable ion rate in fe2o3 affect the electrochemical performance. in this work, to address these issues, we presented a facile method for the synthesis of zeolite on iron-derived mn3o4 with high electrocatalytic supercapacitor properties, carbon distribution efficiency, and rapid electrochemical response of the resulting electrode. in particular, the merits of low carbon distribution and rapid electrochemical response offer promising potential. fuel cells are actually a type of proton exchange membrane that includes a significant share of sustainable development in the future due to environmental issues and the need to achieve clean energy. the advantages of this technology include its compatibility with the environment, good efficiency in energy conversion, and controllability. since this process (oxygen regeneration in a fuel cell) occurs slowly, so this reaction is actually rate-limiting in a fuel cell system. the reason for using carbon materials such as various nanotubes is that they have properties such as high electrical conductivity, uniform particle size, high volume ratio, proper connection with other nanoparticles and easy use on the substrate of other nanocatalysts.
