Catalytic hydrothermal conversion of CO2 captured by ammonia into formate using aluminum-sourced hydrogen at mild reaction conditions

Abstract The catalytic conversion of CO2 captured in aqueous media into formate was studied using aluminum-sourced hydrogen a batch reaction system. To do so, the main ammonia-based absorption derivatives: ammonium carbamate, carbonate and bicarbonate sodium were selected as source. performance different species determined under mild hydrothermal conditions (120 °C), Pd/C 5 wt% catalyst. In these conditions, yield selectivity increase order
