Tailoring local environment of oxygen vacancies by molybdenum doping on MnO2 for enhanced catalytic oxidation of VOCs

Regulating oxygen vacancies by Zn atom doping to anchor and disperse promoter Ba on MgO support to improve Ru-based catalysts activity for ammonia synthesis

“…This spectrum could be deconvoluted into three peaks, attributed to surface adsorbed oxygen (M-OH), OVs, and lattice oxygen (LO), respectively. [44][45][46] By studying the trend, it was observed that with the increase of X, the OVs content initially increased, then decreased, and nally increased again. And the OVs content reached its maximum at X = 0.03.…”

Enhanced catalytic performance for toluene combustion via Ce-doped α-MnO2: efficient balance between toluene adsorption and activation oxidation

“…Volatile organic compounds (VOCs) mainly come from industry, transportation and anthropogenic emissions, 1 and their release into the air has a harmful effect on humans and the natural environment, 2,3 making it necessary to develop effective technologies and materials to control VOC emissions. 4,5 Thus far, many techniques have been developed to remove VOCs, which can mainly be divided into two categories: separation technology and degradation technology. 6–9 However, separation technology cannot completely eliminate VOCs.…”
