Self-passivated CuV₂O₆ as a universal photoelectrode material for reliable and accurate photoelectrochemical sensing

Abstract

Photoelectrochemical (PEC) detection has attracted intensive attention during the past decade. Currently most of the researches focus on improving the sensitivity and selectivity of PEC sensor, but the stability issue...

Anti-interference monitoring of sweat pH: a new sensing mechanism based on the p–n transition potential of a flexible Bi2O3photoelectrode

“…pH sensors based on optics, 19,20 electrochemical (EC) 21,22 and photoelectrochemical (PEC) [23][24][25] methods have been developed. Among these, pH sensors based on the PEC method not only inherit the characteristics of simple structure and fast response of the EC method, but also possess the characteristics of low background signal and high sensitivity of optical methods due to the separation of the light source and electrical signal.…”

Magnetization and optical bandgap of Cu-Mn vanadate-oxide mixed phase nanostructures

“…Transition metal divanadates (MV 2 O 6 or M(VO 3 ) 2 , M is a transition metal) have received great interest due to their application in various fields. Specifically, CuV 2 O 6 nanoparticles have been applied in supercapacitors [1], batteries [2], photocatalytic water remediation [3], photoelectrochemical sensing [4], and photoelectrochemical catalysis [5]. Specifically, copper vanadate (CV) exhibits polymorphism and phase multiplicity, and takes the formulas CuV 2 O 6 , α-Cu 2 V 2 O 7 (Blossite), β-Cu 2 V 2 O 7 (Ziesite), Cu 3 V 2 O 8 (Pseudolynsite), γ-Cu 3 V 2 O 8 (McBirneyite), Cu 5 V 2 O 10 , Cu 11 V 6 O 26 (Fingerite), and Cu 3 (OH) 2 V 2 O 7 .…”
