In situ synthesis of TiO2@NH2-MIL-125 composites for use in combined adsorption and photocatalytic degradation of formaldehyde

Recent Improvement Strategies on Metal-Organic Frameworks as Adsorbent, Catalyst, and Membrane for Wastewater Treatment

“…The Zn 4 O clusters can be viewed as semiconductor dots, and the organic ligands (terephthalate linkers) can absorb light to bring the dots into its excited state, in which the photo-generated electrons are then transferred to the Zn 2+ through ligand-to-metal charge transfer (LMCT). Since then, many other MOFs with similar working principles have been synthesized to specifically function as a photocatalyst, with examples such as UiO-66 [ 86 ] and MIL-125 [ 87 ] being the most commonly found. However, many pristine MOFs (including the aforementioned MOF-5) tend to have modest hydrolytic stability, making its application in wastewater remediation challenging.…”

TiO2@UiO‐66 Composites with Efficient Adsorption and Photocatalytic Oxidation of VOCs: Investigation of Synergistic Effects and Reaction Mechanism

“…The photocatalytic oxidation of toluene and formaldehyde were evaluated at room temperature in a continuous flow reactor. [21,50] The initial concentration of toluene and formaldehyde are 25 ppm and 10 ppm, respectively. 100 mg of samples were used for each experiment and the relative humidity was 60 %.…”

La1-x(Sr, Na, K)xMnO3 perovskites for HCHO oxidation: The role of oxygen species on the catalytic mechanism

“…While particule pollution represents the main risk factor, volatile organic compounds (VOCs) are also of high concern. Formaldehyde (HCHO), classified as carcinogenic to humans (group 1), is among the most significant VOCs, due to its wide use in resins and insulation, but also in plastics, coatings, and textiles as a disinfectant and preservative [2]. Moreover, its gradual release from furniture can take many years, with indoor concentrations in the ppb to ppm level.…”
