The Impact of Amount of Cu on CO2 Reduction Performance of Cu/TiO2 with NH3 and H2O

This study has investigated the impact of molar ratio CO2 to reductants NH3 and H2O as well that Cu loading on reduction characteristics over Cu/TiO2. No optimize reductants’ combination weight in order enhance performance TiO2 been yet. prepared Cu/TiO2 film by particles during pulse arc plasma gun process after coating sol-gel dip-coating process. As Cu, it was regulated change number. characterized SEM EPMA. Additionally, under illumination condition Xe lamp with or without ultraviolet (UV) light. It is revealed CO2/NH3/H2O optimized according Since amount H+ which same electron needed produce CO decided following theoretical reacting NH3, larger increase 4.57 wt% for number 200 optimum condition, whereas quantity per unit UV light 34.1 mol/g 12.0 mol/g, respectively.
