Synthesis and characterization of nanoceria for electrochemical sensing applications.

Nanoceria (cerium oxide nanoparticles: CeO-NPs) has received significant attention due to its biocompatibility, good conductivity, and the ability to transfer oxygen. Nanoceria has been widely used to develop electrochemical sensors and biosensors as it could increase response time, sensitivity, and stability of the sensor. In this review, we discussed synthesis methods, and the recent applications employing CeO-NPs for electrochemical detection of various analytes reported in the most recent four years.

PAN-based activated carbon nanofiber/metal oxide composites for CO and CH adsorption: influence of metal oxide.

In the present study, we successfully prepared two different electrospun polyacrylonitrile (PAN) based-activated carbon nanofiber (ACNF) composites by incorporation of well-distributed FeO and CoO nanoparticles (NPs). The influence of metal oxide on the structural, morphological, and textural properties of final composites was thoroughly investigated. The results showed that the morphological and textural properties could be easily tuned by changing the metal oxide NPs.
