Abstract: Dioxins as a toxic by-product has been valued by the international community. At present, the inhibition of dioxin
generation and its degradation technology has achieved obvious results in meeting the existing emission standards, but the
directional understanding of its generation path at the molecular level and the regulation of its degradation process still needs to
be further explored. This paper reviewed the research progress of inhibiting dioxin generation from aspects such as dioxin catalytic
degradation technology and quantum chemical analysis method. Among them, the discussion on dioxin catalytic degradation
technology focused on the existing technical characteristics such as photocatalytic degradation, metal/metallic oxide catalytic
degradation and high temperature degradation technology; the quantum chemical analysis method mainly introduced the energy
barrier of dioxin generation and degradation path from the molecular level; the prospection was carried out mainly from the solid
waste chemical chain combustion technology and dioxin generation path diagnosis.
