“…The content of real tobacco extraction solution is very complicated, leading to be a big challenge for the remove of real tobacco N‐nitrosamines. To the best of our knowledge, this is the highest degradation efficiency up to now and also much larger than the previous report . This exiting result encourages us to extend the application for other pollutants in tobacco.…”

“…The degradation efficiency of NNN is the highest among them because the average pore size of T2 (0.55 nm) is comparative with the size of NNN (0.54 nm). However, the degradation efficiency of NNK (0.49 nm), NAT (0.57 nm) and NAB (0.59 nm) is lower than NNN due to the larger or smaller molecule size . Thus, it can be concluded that the TiO 2 mesocrystals with microporous size comparable to the size of TSNAs molecule exhibit the best degradation performance.…”

It is essential to control tobacco specific N‐nitrosamines (TSNAs) pollution for the protection of public health, which were identified as the most abundant carcinogens in tobacco and tobacco smoke. Herein, we provide microporous TiO2 mesocrystals as a new material for the remove of TSNAs with high degradation efficiency. The anatase TiO2 mesocrystals with tunable microporous structure were synthesized by a facile method under the acid solution. The TiO2 mesocrystals were firstly used to the remove of TSNAs through photocatalytic degradation. It's exciting that TSNAs of tobacco extraction solution can be almost entirely reduced (up to 97%) by anatase TiO2 mesocrystals after 30 mins through photocatalytic degradation. Moreover, it's found that the microporous size of mesocrystals play a key role on the degradation capability. The TiO2 mesocrystals with microporous size comparable to the size of TSNAs molecule exhibit the best degradation performance. This finding offers a robust microporous material and efficient method for removing the carcinogen like TSNAs as well as other pollutants in environment.

A spectrophotometric method of pararosaniline hydrochloride is reported for rapid determination of formaldehyde (HCHO) content in cigarette smoke in common lab and it has been used to assess the removal of HCHO by zeolites and other porous sorbents conveniently. Through the evaluation in nitrogen flow and cigarette smoke, some porous sorbents were found to exert the attractive performance in capture of HCHO in smoke even in the harsh experiment, which is proven by ISO standard test and provided some candidates for environment protection.

Cigarettes, despite being economically important legal consumer products, are highly addictive and harmful, particularly to the respiratory system. Tobacco smoke is a complex mixture containing over 7000 chemical compounds, 86 of which are identified to have "sufficient evidence of carcinogenicity" in either animal or human tests. Thus, tobacco smoke poses a significant health risk to humans. This article focuses on materials that help reduce the levels of major carcinogens in cigarette smoke; these include nicotine, polycyclic aromatic hydrocarbons, tobacco-specific nitrosamines, hydrogen cyanide, carbon monoxide, and formaldehyde. Specifically, the research progress on adsorption effects and mechanisms of advanced materials such as cellulose, zeolite, activated carbon, graphene, and molecularly imprinted polymers are highlighted. The future trends and prospects in this field are also discussed. Notably, with advancements in supramolecular chemistry and materials engineering, the design of functionally oriented materials has become increasingly multidisciplinary. Certainly, several advanced materials can play a critical role in reducing the harmful effects of cigarette smoke. This review aims to serve as an insightful reference for the design of hybrid and functionally oriented advanced materials.
