| الوصف: | The ammonia synthesis from nitrogen and hydrogen derived from water vapor in the photocatalytic process performed under mild conditions is presented. A new solution of a gas-phase photocatalytic reactor with the bed in the form of a UV transparent glass fiber cloth coated with AEROXIDE® P25 TiO2 was applied. The bed in the reactor is located just above the water surface. The gases circulate from above towards the water surface, where the produced ammonia is easily absorbed and continuously separated from the gas phase, shifting the ammonia synthesis equilibrium towards the product. The highest amount of ammonia (about 1.3 mmol NH4+/g TiO2 after 6 h) was obtained at 20 °C, and with the use of the gaseous mixture containing CO2 (15%), N2 (85%), and water vapour derived from water located at the bottom of the reactor. Carbon dioxide in the reaction environment is simultaneously reduced to carbon monoxide and methane. ; Norway Grants 2014-2021 via the National Centre for Research and Development under the grant number NOR/POLNORCCS/PhotoRed/0007/2019-00. |
