“…[373][374][375][376] H 2 O 2 is also used as a rocket fuel. 377,378 H 2 O 2 is produced by two-electron reduction of O 2 in photosynthesis 68,379,380 as well as in mitochondria. [381][382][383][384] Photosystem I (PSI) can reduce not only NADP + to NADPH but also O 2 to H 2 O 2 via disproportionation of superoxide anion.…”

This review focuses on the production of liquid fuels using solar energy combined with their use in direct liquid fuel cells. The production of formic acid, which is the two-electron reduced product of CO 2 , as a solar liquid fuel as well as a hydrogen storage material is discussed together with its use in direct formate fuel cells. Other CO 2 reduction products such as methanol and formaldehyde as solar liquid fuels as well as hydrogen storage materials are reviewed with the performance of the corresponding fuel cells. The production of nitrogen fixation products such as ammonia and hydrazine is also reviewed together with their fuel cells. Finally, the production of hydrogen peroxide from not only pure water but also seawater and dioxygen in the air using solar energy is discussed and combined with the recent development of one-compartment hydrogen peroxide fuel cells.

“…Maia et al [12] investigated the decomposition of H 2 O 2 90 wt% by bulk catalysts based on Co, Mn and Al mixed oxides in a 2 N thruster. Although it also had a low specific area (6 m 2 /g) after calcination at 900°C, the catalyst performed well in this reaction.…”

This work presents the application of a cobalt and manganese mixed oxides-based catalyst with spinel structure to the decomposition of the storable green monopropellant H 2 O 2 90 wt%. The 5.4 % Co 0.5 Mn 2.5 O 4 /Al 2 O 3 catalyst was tested in a series of continuous and pulsed 2 N thruster firings, yielding a fast and repetitive performance, spontaneously and completely decomposing H 2 O 2 90 wt% without undergoing deactivation or fragmentation during the tests. A specific impulse of 104 s and a characteristic velocity of 881 m/s were reached, so that the characteristic velocity efficiency amounted to 93.7 %. The adiabatic decomposition temperature of the monopropellant (756°C) was also reached, thus evidencing the effectiveness of the 5.4 % Co 0.5 Mn 2.5 O 4 /Al 2 O 3 catalyst. Its excellent activity in the decomposition of H 2 O 2 90 wt% was attributed to the presence of the redox pairs Mn 2 + /Mn 3 + and Co 2 + /Co 3 + , therefore making it a feasible material for low and medium thrust propulsive systems.
