A glucose amperometric biosensor has been prepared by a multilayer deposition on a glassy carbon elec- trode of Co 3 Mn-CO 3 layered double hydroxide, glucose oxidase (GOx) and a biopolymer (carrageenan), respectively. The original transduction step consists in the electrocatalytic oxidation of H 2 O 2 , enzymat- ically formed, in the Co 3 Mn-CO 3 ...

We prepared, for the first time, carbon aerogels support on Pd–WO3 nanorods (CAs/Pd–WO3) hybrid nanocomposite via sol-gel and microwave-assisted methods. The as-prepared CAs/Pd–WO3-modified electrode was used as effective electrocatalyst for nanomolar level detection of mesalazine (MSA). The typical porous nature of carbon aerogels effectively prev...

Metal nitrogen-carbon catalysts have become a promising alternative to platinum-based catalysts in fuel cells due to their high stability and platinum-like activity. However, the corrosion and deactivation of active sites in the solution still restrict the inherent reaction kinetic rate. For this reason, it is important to stabilize the catalyst th...
The unique category of transition metal nitrides has an immense scope as an electron-driven catalyst in redox reactions. However, synthesizing metal nitrides without contamination is very challenging. The residues present in the catalyst might affect catalytic activity. This work reports a simple synthesis of contamination-free nanoscale molybdenum...

Exploring low-cost and earth-abundant oxygen reduction reaction (ORR) electrocatalyst is essential for fuel cells and metal–air batteries. Among them, non-metal nanocarbon with multiple advantages of low cost, abundance, high conductivity, good durability, and competitive activity has attracted intense interest in recent years. The enhanced ORR act...

AbstractTin-nickel sulfide nanocomposite deposited on nickel foam (TNS/NF) displays high electrocatalytic activity toward glucose oxidation. As an enzymeless glucose sensor, the TNS/NF sensing electrode shows a linear range of response from 3 to 5 mM, with a low detection limit of 0.18 μM signal-to-noise ratio of 3 and high sensitivity of 1622.9 μA...

Ultrasonic-enhanced surface-active bismuth trisulfide based core–shell nanomaterials were developed and used as an efficient modified electrode material to construct a highly sensitive antibiotic sensor. The core–shell [email protected] electrode material was directly synthesized by in-situ growth of GCN on Bi2S3 to form core–shell like nanostar (Ti-horn, ...
