“…For the electrochemical performance of different fuels, nanocatalysts have been developed by the sequential reduction method. [37][38][39] These studies have also shown that catalysts prepared by the sequential reduction method increase catalytic performances. Although different nanoparticles and support materials are used, there is no Cd-based catalyst synthesized by the sequential reduction method in the literature for glucose electrooxidation.…”

The sequential sodium borohydride (SBH, NaBH4) reduction method was utilized to prepare the 0.1 % CdSe/CNT, 0.1 % CdS/CNT, 0.1 % (CdS−CNT)/CdTe, and 0.1 % (CdSe−CNT)/CdTe catalysts. The XRD, SEM‐EDS, TEM, and XPS analyses were used to characterize the catalysts. The electrochemical measurements were examined by cyclic voltammetry (CV), chronoamperometry (CA), and electrochemical impedance spectroscopy (EIS) analyses for glucose electrooxidation. The characterization analyses revealed that the desired structure was formed on the support material. The electrochemical analysis results indicated that the 0.1 % (CdSe−CNT)/CdTe catalyst has higher catalytic activity, stability, and resistance compared to other catalysts with a specific activity of 2.4 mA cm−2.

“…Energy is a vital and permanent need for human life and welfare [1][2][3][4][5][6][7]. Fuels such as formic acid [8][9][10], glucose (GA) [11], ethanol [12,13], ethylene glycol [14], hydrazine [15], and methanol [16,17] are principal sources. From these sources, GA is given great significance due to its advantages such as abundance in nature, cheapness, non-toxicity, and easy to transport [18][19][20].…”

In this study, the carbon nanotube supported gold, bismuth, and gold-bismuth(Au/MWCNT, Bi/MWCNT, and Au-Bi/MWCNT) nanocatalysts were prepared with NaBH 4 reduction method at varying molar atomic ratio for glucose electrooxidation (GAEO). The synthesized nanocatalysts at different Au: Bi atomic ratios are characterized via x - ray diffraction (XRD), transmission electron microscopy (TEM), and N 2 adsorption-desorption. For the performance of AuBi/MWCNT for GAEO, electrochemical measurements are performed by using different electrochemical techniques namely cyclic voltammetry (CV), linear sweep voltammetry (LSV), chronoamperometry (CA), and electrochemical impedance spectroscopy (EIS). Monometallic Au/MWCNT exhibits higher activity than Bi/MWCNT with 256.57 mA/mg (0.936 mA/cm 2 ) current density. According to CV results, Au 80 Bi 20 /MWCNT nanocatalyst has the highest GAEO activity with the mass activity of 320.15 mA/mg (1.133 mA/cm 2 ). For Au 80 Bi 20 /MWCNT, central composite design (CCD) is utilized for optimum conditions of the electrode preparation. Au 80 Bi 20 /MWCNT nanocatalysts are promising anode nanocatalysts for direct glucose fuel cells (DGFCs).
