The selection and design of new electrode materials for energy conversion and storage are critical for improved performance, cost reduction, and mass manufacturing. A bifunctional anode with high catalytic activity and extended cycle stability is crucial for rechargeable lithium‐ion batteries and direct borohydride fuel cells. Herein, a high entropy novel three‐dimensional structured electrode with Pr‐doped hollow NiFeP nanoflowers inlaid on N‐rGO was prepared via a simple hydrothermal and self‐assembly process. For optimization of Pr content, three (0.1, 0.5, and 0.8) different doping ratios were investigated. A lithium‐ion battery assembled with NiPr0.5FeP/N‐rGO electrode achieved an outstanding specific capacity of 1.61 Ah g−1 at 0.2 A g−1 after 100 cycles with 99.3 % Coulombic efficiencies. A prolonged cycling stability of 1.02 Ah g−1 was maintained even after 1000 cycles at 0.5 A g−1. In addition, a full cell battery with NiPr0.5FeP/N‐rGO∥LCO (Lithium cobalt oxide) delivered a promising cycling performance of 0.52 Ah g−1 after 200 cycles at 0.15 A g−1. Subsequently, the NiPr0.5FeP/N‐rGO electrode in a direct borohydride fuel cell showed the highest peak power density of 93.70 mW cm−2 at 60 °C. Therefore, this work can be extended to develop advanced electrode for next‐generation energy storage and conversion systems.

“…Among metal oxides, cobalt oxide (Co 3 O 4 ), a multifunctional p-type semiconductor, has emerged as an attractive candidate for different (photo)catalytic end uses, thanks to its operational stability, band gap ( E G ) enabling Vis light harvesting, mixed Co(II)/Co(III) valency, and tunable defect chemistry. ,,,− Nonetheless, to the best of our knowledge, Co 3 O 4 -based systems have never been proposed as De-NO x photocatalysts up to date.…”

The adverse effects of NO x (NO + NO2) gases on the environment and human health have triggered the development of sustainable photocatalysts for their efficient removal (De-NO x ). In this regard, the present work focuses on supported Co3O4-based nanomaterials fabricated via chemical vapor deposition (CVD), assessed for the first time as photocatalysts for sunlight-activated NO oxidation. A proof-of-principle investigation on the possibility of tailoring material performances by heterostructure formation is explored through deposition of SnO2 or Fe2O3 onto Co3O4 by radio frequency (RF) sputtering. A comprehensive characterization by complementary analytical tools evidences the formation of high-purity columnar Co3O4 arrays with faceted pyramidal tips, conformally covered by very thin SnO2 and Fe2O3 overlayers. Photocatalytic functional tests highlight an appreciable activity for bare Co3O4 systems, accompanied by a high selectivity in NO x conversion to harmless nitrate species. A preliminary evaluation of De-NO x performances for functionalized systems revealed a direct dependence of the system behavior on the chemical composition, SnO2/Fe2O3 overlayer morphology, and charge transfer events between the single oxide constituents. Taken together, the present results can provide valuable guidelines for the eventual implementation of improved photocatalysts for air purification.
