Bimetallic PdCu nanoparticle decorated three-dimensional graphene hydrogel for non-enzymatic amperometric glucose sensor

Synthesis of Graphene Supported Pd Nanoparticles for Amperometric NO Gas Sensors

“…[8] The O 1s XPS spectrum of the G/Pd hybrids appears at peaks of 531.7 eV and 533.0 eV, in accordance with previous work, because it comes from the combination of C=O (531.7 eV) and C-O (533.0 eV). [9] The results of the above characterizations clearly show that Pd nanoparticles have been successfully decorated on the surface of GNS, and results are shown in Figure 3. As shown in Figure 3a, the obtained GNS retained a well dispersed and sheet-like morphology.…”

Preparation of Three-Dimensional Graphene/Bimetallic PtPd Nanoparticle Hybrid and Its Electrocatalysts Application for H2O2

“…This might be attributed to the residual oxygen functionalities or oxygen defects on GE sheets which make the assembly between the NPs and the GE sheets more efficient. [11] Figure 3A shows the cyclic voltammograms of the 3D GE/PtPd hybrids modified electrode in various concentrations of H 2 O 2 . It was found that the peak current observed.…”

“…[10] Due to the three-dimensional (3D) GE has ideally interconnected porous structure for catalyst loading, this meens 3D GE based nanohybrids might overcome obstacle of aggregation and stacking, and facilitate the mass transfer and maximize the accessibility for reactants to the active catalyst surfaces.This makes them promisingfor the future development of sensors, fuel cells, supercapacitors and lithium-ion batteries. [11] For example, Dong et al [10] have reported the preparation of a 3D Co 3 O 4 /GE electrode using a simple hydrothermal procedure combined with chemical vapor deposition, and found its high electrocatalytic activity for glucose detection. Yuan et al [11] prepared 3D GE/ PdCu nanoparticles hyrids, which be used in glucose sensor, by a facile one-step hydrothermal strategy.…”

Amperometric Formaldehyde Sensor Based on a Pd Nanocrystal Modified C/Co2P Electrode

“…However, the scarcity and high cost of platinum greatly hinder its application. Much effort has been devoted to developing the platinum-free electrocatalysts, among which palladium-containing catalysts have been proven to be an effective candidate [16,17]. The C/Pd catalyst is a good choice, due to its low cost and competitive intrinsic electrocatalytic activity [18].…”
