This work entails a comprehensive solid-state NMR and computational study of the influence water CO2 partial pressures on CO2-adducts formed in amine-grafted silica sorbents. Our approach provides atomic level insights hypothesised mechanisms for capture under dry wet conditions tightly controlled atmosphere. The method used sample preparation avoids use liquid slurries, as performed previous studies, enabling molecular understanding, by NMR, amounts vapor (down to ca. 0.7 kPa) chemisorption...
The development of photoresponsive textiles with high color contrast, sunlight response, fast coloration/bleaching, and reversible properties has been a major quest for anticounterfeiting, camouflage, UV protection, fashion. WO3 materials are promising building blocks textile applications, but their application limited by slow bleaching under ambient conditions response. Herein, innovative tungsten oxide-based tunable photochromism were produced low-cost, single-step, scalable solvothermal...
The effect of minor amounts water on the CO2 and CH4 adsorption primary secondary amine-functionalised mesoporous silicas (APTES@SBA-15 DEAPTES@SBA15, respectively) was studied with a combination high-pressure gas adsorption, solid state NMR labelled 13CO2 density functional theory (DFT) calculations. Known were pre-adsorbed materials (0.047 to 0.157 mmol∙g−1) performance for compared dry samples. We observed that even when only are present, tertiary material revealed significant enhancement...
