This review selectively summarizes the latest developments in the Pd-based cataysts for low temperature proton exchange membrane fuel cells, especially in the application of formic acid oxidation, alcohol oxidation and oxygen reduction reaction. The advantages and shortcomings of the Pd-based catalysts for electrocatalysis are analyzed. The influence of the structure and morphology of the Pd materials on the performance of the Pd-based catalysts were described. Finally, the perspectives of future trends on Pd-based catalysts for different applications were considered.

“…Also, in the presence of HCHO, Ni(OH) 2 -NaA/CPE displays obvious increase in the current density but no remarkable change was observed in the case of CPE. On the anodic sweep, the peak corresponds to the oxidation of Ni(OH) 2 to nickel oxyhydroxide (NiOOH) at the surface of Ni(OH) 2 -NaA/CPE, on the cathodic sweep, the current results from the reduction of NiOOH to Ni(OH) 2 [41][42][43][44][45]. It is supposed, that at the interface of Ni(OH) 2 -NaA/ CPE and electrolyte in alkaline solution, Ni(II) ions react with OHto produce Ni(OH) 2 which acts as active site in the redox process.…”

Nickel hydroxide doped NaA nanozeolite carbon paste electrode (Ni(OH)2‐NaA/CPE) was employed as simple and efficient sensor for electro‐catalytic oxidation and detection of formaldehyde (HCHO). For this goal, organic template free synthesis of NaA nanozeolite under room‐temperature was performed and characterized. Field emission scanning electronic microscopy (FESEM) technique exhibited the presence of spherical NaA nanozeolite morphology with particle size under 100 nm. The BET surface area and average pore diameter of synthesized NaA nanozeolite were obtained to be 3.622 × 102 m2 g−1 and 5.9 nm, respectively. Carbon paste electrode (CPE) was modified by NaA nanozeolite and then Ni2+ ions incorporated to this electrode to obtain Ni‐NaA/CPE. The values of electron transfer coefficient and mean value of catalytic rate constant for HCHO and redox sites of Ni(OH)2‐NaA/CPE were caculated to be 0.58 and 8.42 × 106 cm3 mol−1 s−1, respectively. The results indicate that Ni(OH)2‐NaA/CPE displays good electrocatalytic activity with respects to HCHO oxidation owing to its mesoporous structure and the large surface area of NaA nanozeolite. Moreover, amperometric studies exhibited that the fabricated electrode has a detection limits of 2.0 μM allowing the quantitative analysis of HCHO in the concentration range from 6.0 × 10−3 to 2.31 × 10−1mM with high sensitivity (1.6716 × 103 μA mM−1).

“…0.1 M H 2 SO 4 ) and their results showed higher electro-catalytic activity than of Pt/C/graphite. On the other hand, Ouf et al [39] and El-Shafei et al [40] conducted the oxidation of ethanol on Au-zeolite NaY/graphite catalyst and Pd-zeolite NaY/graphite catalysts in alkaline medium (i.e. 0.5 M NaOH), respectively.…”
