Abstract

Chlorinated volatile organic compounds (CVOCs) are still a part of the current atmospheric environmental problems that cannot be ignored, but unlike conventional VOCs, the presence of Cl causes various catalyst deactivations in the catalytic process. In this paper, we focus on six common CVOCs and discuss various behavioral mechanisms of the whole catalytic process from six aspects: catalyst selection, factors affecting the catalytic effect, changes in catalytic behavior in the presence of different gases, catalyst poisoning deactivation behavior, degradation products and degradation mechanisms to provide guidance for further development of low-temperature and efficient CVOCs catalysts.


Highlights

  • •The balance of acidity, redox capacity, sufficient sites is very important.

  • •The influence of water is often determined by temperature and concentration.

  • •Promoting Cl desorption is the key factor to reduce by-product formation.

  • •The formation of by-products is related to the type of target CVOCs.

  • •Catalytic CVOCs start from Csingle bondCl bond breaking.
