  "abstract": "Developing shaped catalysts for the low-temperature selective catalytic reduction (SCR) of NO x often results in severe physical detachment and efficiency loss. Building on our previous development of highly active nitrate-incorporated V₂O₅-WO₃/TiO₂ powder catalysts, we investigated the effect of SiO₂ as a structural binder for coating these catalysts onto glass fiber sheets. Coatings with 0-30 wt % SiO₂ were prepared and evaluated. The addition of 10 wt % SiO₂ significantly improved catalyst dispersion, coating uniformity, and mechanical adhesion, successfully preventing the structural degradation typically observed under highly humid operating conditions. Consequently, the SiO₂-containing catalyst demonstrated enhanced physical stability, maintaining consistent NO x removal efficiencies for at least 80 h, whereas the SiO₂-free coating showed progressive deactivation due to physical peeling. The optimized catalyst (10 wt % SiO₂, 4 wt % V₂O₅) achieved a 98.7% NO x removal efficiency at 180 °C under dry conditions and 95.2% in the presence of 10 vol % H₂O. These findings clearly demonstrate that SiO₂ acts as an exceptionally robust structural binder, effectively bridging the gap between highly active fundamental powders and macroscopically stable industrial applications.",
