“…All in all, Mn-Ce codoped V 2 O 5 /TiO 2 catalyst utilizes the electron transfer between Mn, Ce, and V effectively, and the denitration performance at low temperature is greatly improved. This finding may help scientists and engineers to development next generation smart surfaces [24,25] with absorption functionality.…”

Typical p-type semiconductor MnO codoped with n-type semiconductors such as CeO 2 and V 2 O 5 was reported to achieve high efficiency in catalytic NO removal by NH 3 . In this paper, we present novel Mn-Ce codoped V 2 O 5 /TiO 2 catalyst which exhibited an excellent NO conversion efficiency of 90% at 140 ∘ C. By using this codoped catalyst, the best low-temperature activity was greatly decreased when compared with single Mn-or Ce-doped catalyst. According to the characterization results from BET, XRD, and XPS, the codoped catalyst was composed of both CeO 2 and amorphous Mn. The electron circulation formed between doping elements is believed to promote the electron transfer, which may be one of the reasons for excellent low-temperature denitration performance.

“…Furthermore, it is noticed that the extra peak at about 30 h can be seen clearly with addition of TIPA. As reported, the e ect of TIPA on cement hydration can be divided into three phases: (1) adsorb on the surface of cement particles and slightly delay the hydration; (2) hasten the dissolution of ions, especially the ferric ion, to accelerate the formation of AFt; and (3) facilitate the conversion of AFt to AFm [37,38]. It can be inferred that the extra peak should be related to that conversion.…”

Utilization of sea sands and coral aggregate for concrete in ocean construction is increasingly attracting the attention all over the world. However, the potential risk of steel corrosion resulting from chloride in these raw materials was one of the most concerned problems. To take this risk into account, chloride transporting to the surface of steel should be hindered. e formation of Friedel's salt in hydration process is widely accepted as an effective manner for this hindrance. In this study, an attempt to hasten the formation of Friedel's salt by adding triisopropanolamine (TIPA) was done in the cement-fly ash system, with intention to chemical bind chloride, and the chloride-binding capacity at 60 d age was examined. e results show that TIPA can enhance the chloride-binding capacity of cement-fly ash paste at 60 d age, and the reason is that the formation of Friedel's salt can be accelerated with addition of TIPA. e mechanism behind is revealed as follows: on the one hand, the accelerated cement hydration provides more amount of calcium hydroxide to induce the pozzolanic reaction of fly ash, which can hasten the dissolution of aluminum into liquid phase; on the other hand, TIPA can directly hasten the dissolution of aluminum in fly ash, offering more amounts of aluminum in liquid phase. In this case, the aluminum/sulfate (Al/S) ratio was obviously increased, benefiting the formation of Friedel's salt in hydration products. Such results would expect to provide useful experience to promote the chloride-binding capacity of cement-fly ash system.

“…In the aqueous reaction condition, the nonpolar segments of the basic units will collapse and cluster together to try to hide the hydrophobic area from water. Meanwhile, the polar areas attempt to enhance their contact with water [108,109]. For instance, amphiphilic drugs that can be self-assembled into nanostructures were developed based on hydrophobic interactions.…”
