Spin‐State Engineering via Cr3+ Incorporation in Co3O4 Spinel for Efficient Bifunctional Oxygen Electrocatalysis

Carbon Energy, EarlyView.
Cr doping causes distortion of the CoO6 octahedron, modifies the spin state of CoOh, and enhances the bifunctional catalytic activity. ABSTRACT The primary challenge in rechargeable Zn‐air batteries lies in developing a catalyst capable of simultaneously improving performance for oxygen reduction reaction (ORR) during discharge and oxygen evolution ...

Photocatalytic Degradation of PFOA with Porous Lanthanoid Perovskites Nano Catalyst

Chemie Ingenieur Technik, EarlyView.
Photocatalytic degradation of PFOA was studied using nickel‐ and lanthanide‐doped perovskites under UV–VIS irradiation. Catalyst characterization confirmed successful doping, with Ni/NdMnO3 showing the highest photocatalytic efficiency. Degradation occurred via C–C bond cleavage, forming transformation products PFHpA and PFHxA.

A study of Ni‐Co/CeO2 catalyst derived from metal–organic framework for dry reforming of methane

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The efficacy of cobalt‐doped, MOF‐derived catalysts for dry reforming of methane (DRM) was examined. The focus was on the influence of varying nickel and cobalt molar ratios on catalytic performance. Three catalysts with Ni:Co ratios of 1:1, 1:0.5, and 0.5:1, were synthesized and tested with cerium oxide as a constant support. The DRM reaction
