Abstract Formaldehyde (HCHO), a common pollutant in industrial productions and indoor environments, poses health risks to humans. Thermal catalytic oxidation has been regarded as an effective approach eliminate formaldehyde pollution due its environmental benefits operational convenience. In this study, Pd‐based catalyst with high dispersion of Pd was prepared by facile impregnation method choosing the appropriate calcination temperature MgFe 2 O 4 support, which demonstrated excellent activity robustness during long term test 60 h conducted at 30 °C WHSV 30,000 mL/(g‐h). A comprehensive set characterizations, such N physisorption, CO chemisorption, STEM, XRD, XPS, H ‐TPR, ‐TPD, were employed. The results revealed that outstanding stability resulted from Pd, good oxygen mobility, strong antioxidant capacity low desorption temperature, amount temperature. This study presents palladium significant application potential removal.

Protonic ceramic fuel cells (PCFCs) offer a promising avenue for sustainable energy conversion, however, their commercial potential is hindered by sluggish proton-involved oxygen reduction reaction (P-ORR) kinetics and inadequate durability of cathode materials. Here, novel single-atom Ru anchor on BaCe0.125Fe0.875O3-δ (BCF) perovskite, synthesized facile scalable solid-state approach, as PCFCs reported. Theoretical experimental analyses demonstrate that the BCF, characterized unique 4-coordinate Ru-O-Fe configuration, not only induces reverse hydrogen spillover but also acts an active site P-ORR. The application optimized 2Ru-BCF (2 wt.% Ru) in single cell delivers exceptional peak power density 1.78 W cm-2 at 700 °C, along with excellent operational stability over 200 h. These findings provide new insights into engineering, advancing viability PCFCs.
