(2023). On the Selectivity of Simultaneous CO2 and N2 Reduction Using TiO2/Carbon Sphere Photocatalysts Prepared by Microwave Treatment and Mounted on Silica Cloth. Materials, 16, 5810. doi 10.3390/ma16175810.https://hdl.handle.net/20.500.12539/1827NOR/POLNORCCS/PhotoRed/0007/2019-00This paper presents new photocatalysts obtained by treating carbon spheres (CS) and TiO2 in a microwave reactor at a pressure of 20 atm and a temperature of up to 300 °C for 15 min and then depositing TiO2/CS composites on glass fibre cloths. Such highly CO2-adsorbing photocatalysts showed photoactivity in the simultaneous water-splitting process, generating H2, reducing CO2 to CO and CH4, and reducing N2 to NH3. In addition, calculations of the hydrogen balance involved in all reactions were performed. Adding 1 g of carbon spheres per 1 g of TiO2 maintained the high selectivity of nitrogen fixation at 95.87–99.5%, which was continuously removed from the gas phase into the water as NH4+ ions.enUznanie autorstwa 3.0 Polskaphotocatalytic CO2 reductionnitrogen fixationtitanium dioxidecarbon spheresmicrowave reactorDyscyplina::Nauki inżynieryjno-techniczne::Inżynieria chemicznaArticle10.3390/ma16175810
