In this study, a laser‐induced graphene (LIG) loaded platinum nanoparticles (PtNPs) was prepared for precise, rapid and non‐enzymatic electrochemical detection of hydrogen peroxide (H2O2). The commercial PI films were used as the substrate of LIG. In order to improve the electrochemical performance of LIG, a layer of PtNPs catalyst was fabricated through a magnetron sputtering process on the surface of LIG (PtLIG). Under optimized conditions, a linear relationship between H2O2 reduction current and H2O2 concentration was recorded, the correlation coefficient R2 is 0.9919 with the detection limit of 0.1 μM (S/N=3) and the sensitivity of 248.4 μA mM−1cm−2. Moreover, the PtLIG exhibits excellent selectivity, reproducibility and repeatability. Because of these remarkable advantages, we believe that PtLIG will provide a wider range of applications in biosensors and bioelectronic devices.

Highlights:• Detail Pd cluster structure by the ex-situ Extended X-ray Adsorption Fine Structure (EXAFS) method.• Evaluate Pd/Y-zeolite nanoparticle size under calcinations and reduction temperature.• Measure Pd nanoparticle electrochemical activity in electrolyte solution.• Discuss electrochemical reaction behaviour with respect to Pd particle size.• Explore Pd particle location and Pd particle migration and electrochemical behaviour. AbstractA laboratory made 1.5 wt% Palladium (Pd) zeolite electrocatalyst is investigated using the Extended X-ray Adsorption Fine Structure (EXAFS) and Cyclic Voltammetry (CV) techniques to reveal Pd structure and resultant electrochemical performance. It was found that the Abstract ID 23 -International Journal of Hydrogen Energy 2 electrochemical activity of hydrogen charger transfer in the hydride region increased for electrocatalyst with large-size particles made at high temperature of 400 o C, compared to those with small-size particles calcined and reduced at temperature below 360 o C, at which no major discrepancies were observed between catalysts of different sizes. Furthermore, Pd particle location has played an important role to enhance electrocatalyst performance. The Pd atom tends to remain at small cages, i.e. zeolite sodalite cages or hexagonal prisms at calcinations and reduction temperatures below 360 o C. When temperature increases to about 400 o C, the majority Pd atoms tend to migrate from zeolite small cages to supercages and zeolite external structures with enhanced electrochemical performance.

“…33 Y zeolite possesses distinctive features like high surface area, large pore volume, high hydrothermal stability and biocompatibility which is advantageous for its use in catalysis, development of adsorbents, etc. [34][35][36] Elsewhere, in recent years, the inorganic spinel cobalt ferrite nanoparticles (CoFe 2 O 4 NPs) with band gap energy 1.76 eV have grabbed much attention referred to their different properties such as coercivity, anisotropy, saturation, magnetization, etc. 37,38 Thereupon, these salient and applicable features make magnetic CoFe 2 O 4 NPs suitable for several elds for instance drug delivery, 39 magnetic uid hyperthermia, 40 microwave devices, 41 permanent magnets, 42 catalysis, 43 etc.…”
