Aluminium bismuthate nanorods and the electrochemical performance for detection of tartaric acid

Growth of Li Doped Bismuth Oxide Nanorods and its Electrochemical Performance for the Determination of L-Cysteine

“…The reaction timedependent results suggest that the nanorods originate from the irregular and nanosphere-shaped structures which is similar to those reported by other groups. [5][6][7]21 With the increase of the reaction time, the diameter and length of the nanorods increase continuously. Figure 4 shows the SEM images of the products obtained from the hydrothermal conditions of 80 ºC and 120 ºC, respectively for 24 h. The products are totally composed of elliptic particles with the size of 150 nm when the hydrothermal temperature is 80 ºC (Figure 4a and 4b).…”

“…1,2 Nanoscale bismuth oxide has also attracted much attention owing to electrochemical catalysis and electrochemical stability for the analysis of biological molecules. 3,4 Glassy carbon electrode (GCE) modified with nanoscale Bi-containing materials, such as zinc bismuthate nanorods, 5 aluminium bismuthate nanorods, 6 Bi 2 O 3 nanorods 7 and Bi 2 O 3 microscale and nanoscale particles 8 has shown good catalytic activity for the electrochemical reduction or oxidation of various biological molecules. The performance of the materials can be improved by doping metal ions.…”

Synthesis of cobalt ferrite nanoparticles by means of confined impinging-jets reactors.

“…The particles are stable and reproducible in terms of their size and distribution. Han et al [4] have also compared the performance of their CIJ-D mixer with the vortex mixer, which can operate at unequal flow rates [19], to make β-carotene-containing particles over a series of turbulent conditions. On the basis of dynamic light scattering measurements, the new CIJ-D mixer produces stable particles of a size similar to the vortex mixer.…”

“…A hydrothermal method is widely used during last years for nano sized oxides allowing to control morphology of the dispersed products by means of process parameter variation (temperature, pressure, composition of solution and its concentration, duration of the process etc.) [19].…”

Synthesis and properties of BiDy composite electrode materials in electrochemical sensors

“…27,28 Bismuth (Bi) based and dysprosium (Dy) based composites belong to important rare earth-based materials which exhibit great application potential in the fields of the electrochemical sensors, lithium ion batteries, super-capacitors and catalysts owing to their large active surface, good electron transport, interface dominated performance, enhanced electrode conductivity, superior chemical and thermal stability, and non-toxicity. [29][30][31][32][33][34] Double perovskite metal oxides A 2 DyBiO 6 (A = Mg, Ca, Sr, and Ba) were synthesized using the sol-gel auto-combustion method and showed good dielectric properties. 35 Using the L-cysteine selfassembly on the surface of the gold nanoparticles and nanoscale Bi 2 O 3 (L-cysteine/AuNPs/Bi 2 O 3 ) modified glassy carbon electrode (GCE), the L-cysteine/AuNPs/Bi 2 O 3 modified GCE showed good sensitivity and selectivity for the determination of Cu(II) with a detection limit of 5 Â 10 À11 M. 36 The Bi 2 O 2 CO 3 / reduced graphene oxide (rGO) electrodes showed excellent capacitive performance due to their high specific capacitance and high cycle property.…”
