A complex-sequestered strategy to fabricate Fe single-atom catalyst for efficient oxygen reduction in a broad pH-range

CuII/CuI decorated N-doped carbonaceous electrocatalysts for the oxygen reduction reaction

“…2,[7][8][9] Therefore, many research efforts are currently undergoing focused on developing new catalysts containing abundant and affordable elements, which can outperform Pt-based materials and overcome their drawbacks, especially for simpler cell management designs. Transition metals supported on N-doped carbonaceous materials (M-NCs) such as Fe [10][11][12] or Co 13,14 have shown good ORR activity and stability and they have been broadly analysed as catalysts in cathodes. 2,[15][16][17] However, their practical applicability is limited due to their ability to participate in the Fenton-like radical oxygen activation pathways, and hence, promoting degradation of the polymeric membrane in polymer membrane fuel cells.…”

Fe Single‐Atom Catalyst for Efficient and Rapid Fenton‐Like Degradation of Organics and Disinfection against Bacteria

“…The catalyst of Fe SA/NPCs is synthesized via a complexsequestered strategy as previously reported (Figure 1). [41] Briefly, agarose, iron(III) nitrate nonahydrate, and urea are used as the precursors of carbon, iron, and nitrogen, respectively. It is noteworthy that agarose, a natural and easily accessible reagent, also plays another important role as a complexant to coordinate with iron(III) ion in our synthesis.…”

“…[31,40] Our previous study has demonstrated that a catalyst with isolated single Fe atoms of Fe-N 4 coordination anchored on N-doped porous carbon (Fe SA/NPCs) possesses superior catalytic activity on oxygen reduction reaction (ORR). [41,42] Furthermore, other studies have also shown that anchoring single atoms of transition metals on N-doped carbon substrates can dramatically improve the degradation of bisphenol A (BPA). [43][44][45] Hence, it is envisioned that SACs of transition metals on carbonaceous substrates can also function in Fenton-like process, which can be used in pollutant degradation and sterilization.…”
