202222 The presence of alkali metals in flue gas is still an obstacle to the practical appliion of alysts for selective alytic reduction SCR of NOx by NH3 Polymeric vanadyl species play an essential role in ensuring the effective NOx abatement for NH3SCR However polymeric vanadyl would be conventionally deactivated by the poison of alkali metals such as potassium
201911 Silicon carbide SiC is popular among researcher as a refractory material because SiC can be stable above 2700 °C and it has high strength ~ 800–1000 MPa and fracture toughness 6–10 MPa m 1/2It can also be used in aggressive environments due to the formation of a protective coating of SiO 2 on its surface at high temperature SiC refractories are

201231 The fact that stable nanotube structures were also found for NaCl and KBr suggests that this geometry may be widely implemented in material sciences and that ionic nanotubes can be as stable as the typical B1 and B2 crystal structures normally associated with ionic solids thus opening a new possibility for the 3D macroassely of alkali halide
A thorough understanding of the deactivation mechanism by alkalis is of great importance for rationally designing improved alkaliresistant deNOx alysts but a traditional ionexchange mechanism cannot often accurately describe the nature of the deactivation thus hampering the development of superior alysts Here we establish a new exchangecoordination
