Interfacing spinel NiCo2O4 and NiCo alloy derived N-doped carbon nanotubes for enhanced oxygen electrocatalysis

A new electrochemical DNA biosensor for determination of anti-cancer drug chlorambucil based on a polypyrrole/flower-like platinum/NiCo2O4/pencil graphite electrode

“…It has greater electrochemical potential and electronic conductivity when compared with Ni and Co oxides alone. [36][37][38] In addition, metal oxide semiconductor doping can create an excess or deciency of the count of electrons that can modulate the semiconductor conductivity. The noble metals such as Au, Ag, Pd and Pt can be used for doping the NiCo 2 O 4 nanostructures to enhance active surface area and promote electronic properties, resulting in greater sensor response compared to NiCo 2 O 4 .…”

Integration of partially phosphatized bimetal centers into trifunctional catalyst for high-performance hydrogen production and flexible Zn-air battery

“…The integration of oxygen reduction reaction (ORR), oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) performance is critical for clean energy devices [3][4][5]. For instance, the large-scale commercialization of Zn-air batteries (ZABs), as a promising next-generation energy storage system, requires efficient ORR and OER catalysts [6][7][8][9][10][11]. To date, the highly effective catalysts for such reactions have been limited to materials based on state-of-theart noble metals such as Pt, Ir, and Ru group metals.…”

Layer-by-layer construction of in situ formed polypyrrole and bacterial cells as capacitive bioanodes for paper-based microbial fuel cells

“…Microbial fuel cells (MFCs) are a green energy technology in which live electroactive bacteria are harnessed as biocatalysts to oxidize organic fuel, simultaneously producing electricity. [1][2][3][4][5][6][7] As an important branch of MFCs, paper-based microbial fuel cells (PBMFCs) have greatly attracted public attention. 8,9 Unlike traditional MFCs, most components of PBMFCs are fabricated with paper, which endows features like low cost, disposability, portability, and accessibility to paper-based sensing devices.…”
