Traditional catalysts for oxygen reduction reactions primarily rely upon rare-earth elements such as platinum (Pt). Although these materials have exceptional electrocatalytic efficiency, their high cost limits their potential for large applications.
Recently, studies have revealed that Iron Carbide (Fe3C) Powder is an encouraging stimulant to change rare-earth elements, generally as a result of the unique digital structure and high stability of Fe3C. Fe3C powder can maintain stability under various operating conditions and carry out well also in severe settings. In order to more maximize the catalytic efficiency of Fe3C powder, researchers adopted a series of innovative design methods, such as incorporating Fe3C powder with nitrogen-doped carbon nanotubes to form a reliable bifunctional oxygen electrocatalyst. This structure not just enhances the conductivity of the catalyst however likewise enhances its application efficiency in zinc-air batteries.

Advantages of Fe3C powder as ORR catalyst
Inexpensive basic materials: The major parts of Fe3C powder are iron and carbon, both of which are really bountiful and economical. Compared to precious metal stimulants such as platinum, it substantially lowers the cost of drivers.
Easy to prepare: Fe3C powder can be prepared by various approaches, including yet not restricted to chemical vapor deposition, solvothermal method, and so on. These approaches are reasonably easy and cost-efficient.
Exceptional ORR activity: Fe3C powder exhibits good ORR activity in both acidic and alkaline atmospheres and, in many cases even methods or surpasses the performance of rare-earth element stimulants.
Special digital framework: The distinct electronic structure of Fe3C aids to enhance the adsorption capacity and catalytic effectiveness of drivers for oxygen particles, thus improving ORR efficiency.
Deterioration resistance: Fe3C powder exhibits high stability in acidic environments, which mainly solves the problem of rust of nonprecious steel stimulants in acidic atmospheres.
Long-term procedure: Throughout lasting use, Fe3C powder can keep steady catalytic efficiency, decrease the regularity of stimulant replacement, and reduced maintenance expenses.
Architectural law: Fe3C can further boost its catalytic activity via surface modification or composite with various other materials, such as combining it with graphitized carbon layers to improve the catalytic effect.
Functionalization: By introducing other elements such as nitrogen, phosphorus, etc for functionalization therapy, the efficiency of Fe3C powder can be more enhanced, making it preferable for specific application circumstances.
