In contrast to previous defect engineering methods, the preparation of amorphous materials can obtain abundant sites through a simple way, which is expected effectively degrade Volatile Organic Compounds (VOCs) under milder conditions. However, in-depth and systematic studies in this area are still lacking. Novel types CeMnx catalysts with defects were prepared hydrothermal synthesis used for Cl-VOCs catalysis first time. Experimental characterizations DFT calculations proved that Ce doping induced MnO2 lattice distortion, led transformation into an structure formation sites. It was observed CeMn0.16 able eliminate chlorobenzene (CB) at 200 °C, CO2 yields selectivity inorganic chlorine significantly higher than MnO2. The 18O isotope kinetic experiments revealed interfacial reaction process followed MVK mechanism. large number oxygen vacancies accelerated migration from interior exterior, enhancing ability trap gas-phase oxygen. Mn4+ acted as main active center participate CB catalysis, resulting reactive species (ROS) Mn3+-[O2–]-Ce4+ further entire oxidation cycle.

The lattice oxygen mechanism (LOM) plays a critical role in the acidic evolution reaction (OER) as it provides more efficient catalytic pathway compared to conventional adsorption (AEM). LOM effectively lowers energy threshold of and accelerates rate by exciting atoms catalyst directly participate OER process. In recent years, with increase in-depth understanding LOM, researchers have developed variety iridium (Ir) ruthenium (Ru)-based catalysts, well non-precious metal oxide optimized their performance through different strategies. However, still faces many challenges practical applications, including long-term stability precise modulation active sites, application efficiency real electrolysis systems. Here, we review OER, analyze its difference traditional AEM new (OPM) mechanism, discuss experimental theoretical validation methods pathway, prospect future development electrocatalyst design conversion, aiming provide fresh perspectives strategies for solving current challenges.
