Pd17Se15-Pd3B nanocoral electrocatalyst for selective oxygen reduction to hydrogen peroxide in near-neutral electrolyte

Juyeon Lee et al.

Summary: An efficient approach to shift the reaction pathway from the 4e(-) ORR to the 2e(-) ORR is by fabricating precious metal compounds. This study demonstrates the high 2e(-) ORR activity and selectivity of a nanocoral-shaped Pd-based compound (Pd-Se-B NC), which exhibits one of the highest H2O2 electrosynthesis activities reported to date in neutral media. The chemical states and composition of the Pd-Se-B NC remained almost intact even after sustained electrocatalysis.

Surface O2- regulation on POM electrocatalyst to achieve accurate 2e/4e-ORR control for H2O2 production and Zn-air battery assemble

Yang Zheng et al.

Summary: Polyoxometalate, after vulcanization, exhibits a two-electron feature in oxygen reduction reaction, with weakened OOH* adsorption and enhanced selectivity. In contrast, pure polyoxometalate shows a typical four-electron character. Vulcanized polyoxometalate also demonstrates photothermal-induced advanced oxidation process for degrading organic pollutants, with a Fe2+ free character and wide pH scope in comparison to traditional Fenton reaction. Additionally, the influence of structure on oxygen reduction reaction selectivity for polyoxometalate is clarified in this work.

Tailoring Acidic Oxygen Reduction Selectivity on Single-Atom Catalysts via Modification of First and Second Coordination Spheres

Cheng Tang et al.

Summary: This study demonstrates that the molecular-level local structure, including first and second coordination spheres, plays a critical role in determining the selectivity of catalytic reactions. By modifying the first and second coordination spheres of Co-SACs, it is possible to tailor the oxygen reduction reaction selectivity. The unique selectivity change originates from the structure-dependent shift of active sites, leading to improved activity and selectivity for acidic H2O2 electrosynthesis.

Jae Hyung Kim et al.

Summary: Reversible control of the coordination structure in atomically dispersed electrocatalysts can be achieved via ligand exchange reactions to modulate their reactivity for oxygen reduction reaction. The CO-ligated Rh catalyst shows higher ORR activity, while the NHx-ligated catalyst exhibits higher H2O2 selectivity. This reversible ligand exchange strategy is applicable to Ir- and Pt-based catalysts as well.
