Abstract The oxygen evolution reaction (OER) activity of transition metal (TM)‐based (oxy)hydroxide is dominated by the number and nature of surface active sites, which are generally considered to be TM atoms occupying less than half of surface sit

Abstract Layered lithium‐rich manganese‐based oxide (LRMO) has the limitation of inevitable evolution of lattice oxygen release and layered structure transformation. Herein, a multilayer reconstruction strategy is applied to LRMO via facile pyrol

Abstract The lattice‐oxygen‐mediated mechanism is considered as a reasonable mechanism for the electrochemical catalytic oxygen evolution reaction (OER) of NiFe layered double hydroxides (LDHs). A NiFe LDH with distinct lattice contraction and mi

Cobalt-rich perovskite oxides play a paramount role in catalyzing oxygen evolution reaction (OER) on account of their acceptable intrinsic activity but are still challenging due to the high costs and undesired stability. In response to the defects, h

Catalytic methane combustion was carried out over YSZ, Pd/YSZ and Rh/YSZ between 200 and 700 °C. Despite similar light-off curves for Pd/YSZ and Rh/YSZ between 200 and 450 °C, isotopic exchange experiments using CD4 and 18O2 revealed different beha
