TiO2-Based Photocatalysts for Removal of Low-Concentration NOx Contamination

Catalysts, Journal Year: 2025, Volume and Issue: 15(2), P. 103 - 103

Published: Jan. 22, 2025

The removal of low-concentration NOx contamination in the urban atmosphere has been regarded as an urgent issue to be solved context urbanization. In past few decades, TiO2 photocatalysis intensively investigated economical, efficient, and environmentally friendly means for abatement NOx. Up now, however, there have reviews focusing on TiO2-based photocatalysts photocatalytic NO removal. this review article, we will summarize latest advances with photocatalysts, which endowed reputation being star catalysts atmospheric environment remediation. We begin a survey mechanistic investigations removal, situ Fourier Transform Infrared Spectroscopy (in FTIR) Electron Paramagnetic Resonance (EPR) studies theoretical calculation reaction pathways Density Functional Theory. then introduce test methods ISO standards discuss effect parameters (catalyst mass, irradiation conditions, temperature, humidity). Meanwhile, also elaborate modification enhance efficiency progress recent years modified applied abatement. Lastly, put forward some feasible suggestions. end, may provide inspiration designing more effective removing from ambient atmosphere.

Recent Progress on Low-Temperature Selective Catalytic Reduction of NOx with Ammonia

Molecules, Journal Year: 2024, Volume and Issue: 29(18), P. 4506 - 4506

Published: Sept. 23, 2024

Selective catalytic reduction of nitrogen oxides (NOx) with ammonia (NH3-SCR) has been implemented in response to the regulation NOx emissions from stationary and mobile sources above 300 °C. However, development NH3-SCR catalysts active at low temperatures below 200 °C is still needed improve energy efficiency cope various fuels. In this review article, recent reports on low-temperature are systematically summarized. The redox property as well surface acidity two main factors that affect activity. strong beneficial for activity but responsible N2O formation. multiple electron transfer system more plausible controlling properties. H2O SOx, which often found flue gas, have a detrimental effect activity, especially temperatures. competitive adsorption can be minimized by enhancing hydrophobic catalyst. Various strategies resistance SOx poisoning also discussed.
