Volatile organic compounds (VOCs) in cooking oil fumes need to be efficiently removed due the significant damage they cause environment and human health. This review discusses emission characteristics, which are influenced by different temperatures, oils, cuisines. Then, various fume purification methods mainly classified into physical capture, chemical decomposition, combination methods. VOCs removal rate, system operability, secondary pollution, application area, cost compared. The catalytic combustion method was found have advantages of high VOC efficiency, environmental protection, low cost. Therefore, last part this focuses on research progress summarizes its mechanisms catalysts. Marse-van Krevelen (MVK), Langmuir-Hinshelwood (L-H), Eley-Rideal (E-R) analyzed. Noble metal non-noble catalysts commonly used. former showed excellent activity at temperatures strong adsorption electron transfer abilities, but price limits application. transition metals primarily comprise latter, including single composite Compared catalysts, interaction between can further enhance performance.

In the early-stage diagnosis of lung cancer, low-concentration (< 5 ppm) volatile organic compounds (VOCs) are extensively identified to be biomarkers for breath analysis. Herein, urchin-like sodium (Na)-doped ZnO nanoneedles were synthesized through a hydrothermal strategy with addition different contents citric acid. The Na-doped gas sensor 3:1 molar ratio Na+ and acid showed outstanding sensing properties an optimal selectivity various VOCs (formaldehyde, isopropanol, acetone and ammonia) based on working temperature regulation. Specifically, significantly enhanced sensitivity (21.3 @ compared pristine (~ seven-fold), low detection limit (LOD) (298 ppb), robust humidity resistance long-term stability formaldehyde performances obtained, which can attributed formation higher concentration oxygen vacancies (20.98%) active electron transitions. Furthermore, improved mechanism was demonstrated by exquisite band structure introduction additional acceptor level resulted in narrowed bandgap ZnO.
