Special Issue Information

Dear Colleagues,

Volatile organic compounds (VOCs) have significant adverse effects on human health, which are crucial contributors to global morbidity and mortality. As one kind of main pollutants, VOCs may be smelly, toxic, mutagenic, and carcinogenic. VOCs originate from many industrial processes. It is important to accurately understand the emission characteristics of VOCs, such as the emissions of different links and different emission sources, emission structures, control measures, and emission reduction potential, for their control. In recent years, substantial research has been conducted around the world, exploring the emission characteristics and control technology of VOCs. Up to now, various technologies have been explored for VOC removal, such as adsorption, thermal catalytic oxidation, photocatalytic degradation, plasma oxidation, and photothermal catalytic decomposition.

Original research, systematic reviews, and model studies related to the theme of this Special Issue are welcome. Example topics include, but are not limited to, the following:

  • Emission characteristics and control analysis of VOCs;
  • Oil vapor recovery;
  • Contribution of VOCs to ozone and secondary organic aerosols;
  • Abatement technology of VOCs;
  • VOC characteristics and emissions of gasoline vapor;
  • Health risk assessment.

Since actual industrial emissions contain a wide range of volatile organic compounds, studies into the simultaneous catalytic degradation of multi-component VOCs are essential. This work developed Pd-CeZrOx samples for the simultaneous elimination of benzene and toluene. Firstly, CeZrOx supports were synthesized using several methods (co-precipitation, CTAB template co-precipitation, and sol–gel method). Pd active species were then added into the 1.0Pd-CeZrOx samples using the impregnation procedure. XRD, BET, NH3-TPD, Raman, EPR, XPS, and H2-TPR were utilized to analyze the as-prepared Pd-CeZrOx samples. The catalytic performance tests reveal that the performance of 1.0Pd-CeZrOx-CTAB outperforms that of 1.0Pd-CeZrOx-PM and 1.0Pd-CeZrOx-CASG, and 1.0Pd-CeZrOx-CTAB displays superior catalytic activity for both benzene and toluene oxidation. The improved redox properties, the abundant surface oxygen vacancies, and the surface Pd2+ species of the 1.0Pd-CeZrOx-CTAB sample may be responsible for the simultaneous degradation activity of benzene and toluene.
