One-step pyrolysis synthesis of ternary (P,S,N)-doped graphene as an efficient metal-free electrocatalyst for the oxygen reduction reaction

“…Regenerative fuel cells are a class of promising electrochemical energy conversion and storage devices due to their environmental friendliness and high energy yield. 2,3 Meanwhile, the oxygen reduction reaction (ORR) is the key cathodic electrode process in regenerative fuel cells, which could have an effect on the efficiency of electrochemical energy conversion. [4][5][6] Hence, developing highly efficient catalysts is crucial for the oxygen reduction reaction process.…”

Recent development and challenges in fuel cells and water electrolyzer reactions: an overview

“…These catalysts are unique with many interesting properties such as defects due to long-range disordered lattice, defects-created low-coordination active sites, which have been reported to increase the catalytic activity. 81,82 In addition, the synergistic effects of doping and alloying elements also contribute to higher catalytic activity.…”

Coordination polymer derived Fe–N–C electrocatalysts with high performance for the oxygen reduction reaction in Zn–air batteries

“…Nowadays, clean and sustainable energy conversion devices, such as fuel cells and metal-air batteries, have been extensively explored to address environmental pollution and fossil fuel energy shortages. [1][2][3][4] The cathodic oxygen reduction reaction (ORR), however, possesses an inherent sluggish kinetics that significantly limits the efficiency of energy conversion and thus the output of the devices. [5][6][7] Currently, noble metal Ptbased (Pt/C, PtNi, etc.)…”
