Mechano-thermal milling synthesis of atomically dispersed platinum with spin polarization induced by cobalt atoms towards enhanced oxygen reduction reaction

Ni3Fe/Ni3Fe(OOH)x dynamically coupled on wood-derived nitrogen doped carbon as a bifunctional electrocatalyst for rechargeable zinc–air batteries

“…7,8 The prohibitive cost and scarce resources of noble metals, especially the unsatisfactory catalytic stability in batteries, have severely restricted the widespread application of noble metal-based catalysts. 9,10 Therefore, the rational design and synthesis of cost-effective and high-performance bifunctional electrocatalysts without relying on noble metals is significant for the development of ZABs. However, a severe challenge lies ahead of all researchers in the energy catalysis and ZABs field because of the lack of a chemical foundation for the detailed knowledge of the structure of catalysts and the mechanism of catalytic reaction.…”

A Low‐Cost, Durable Bifunctional Electrocatalyst Containing Atomic Co and Pt Species for Flow Alkali‐Al/Acid Hybrid Fuel Cell and Zn–Air Battery

“…[24] In the past few years, many studies relating to the Pt species anchored on modifying Co-N-C support electrocatalysts have been reported. For instance, Cheng et al [25] constructed dual Pt and Co atoms catalyst on nitrogen-doped carbon (PtCo-NC). Single Co atoms can tune the spin polarization of adjacent Pt atoms, boosting the ORR activities for PtCo-NC.…”

Engineering a High-Loading Sub-4 nm Intermetallic Platinum–Cobalt Alloy on Atomically Dispersed Cobalt–Nitrogen–Carbon for Efficient Oxygen Reduction in Fuel Cells

“…Proton-exchange membrane fuel cells (PEMFCs) are attracting a significant amount of attention owing to their high energy efficiency and environmentally sustainable features. , Nonetheless, their large-scale deployment faces a critical impediment of high costs due to the extensive use of Pt-based catalysts to catalyze the sluggish cathodic oxygen reduction reaction (ORR) process. − An effective approach is to adopt high-performance and structurally ordered Pt-based catalysts and further decrease the Pt loading (milligrams of Pt per square centimeter) of the membrane electrode assembly (MEA) electrode to reduce the use of platinum. , Over the past decade, structurally ordered Pt-based bimetallic catalysts (PtM, such as PtFe, PtCo, PtNi, etc.) have emerged as promising candidates for reducing the use of Pt catalysts because of their excellent activity and sufficient durability. , However, the outstanding ORR catalytic activities observed in the case of these catalysts have proven challenging to replicate with MEA performance at low Pt loadings. − …”

“…have emerged as promising candidates for reducing the use of Pt catalysts because of their excellent activity and sufficient durability. 8,9 However, the outstanding ORR catalytic activities observed in the case of these catalysts have proven challenging to replicate with MEA performance at low Pt loadings. 10−12 Recently, many efforts have shown that decreasing MEA electrode loadings is feasible for the anode side but not for the cathode side.…”
