“…The gauzes themselves are easy to handle thereby facilitating installation and compression within the chamber. Transition metal oxides have been used as catalysts for decomposition of H 2 O 2 [10]- [16] because of their significant activities in which pure and mixed manganese oxides are a prominent choice for H 2 O 2 decomposition [9], [12]- [17]. Therefore, the primary alternative of silver is to use manganese oxide catalyst in liquid or solid form, which will provide a faster reaction and long-term stability than silver, enabling a rapid start-up characteristic [18].…”

“…A possible explanation for this might be that nanoscale MnO 2 is one of the most active catalysts in promoting the decomposition of H 2 O 2 in the range of pH 5–9 52 . The decrease in Fe‐EDTA degradation with increasing pH from 8.5 to 9 is attributed to the intrinsic instability of H 2 O 2 in alkaline solution 30 …”

“…Consequently, the alkaline Fenton system of Fe 2+ ‐EDTA/H 2 O 2 was used to emulate the generation of • OH in regeneration of the ferrous chelate in this work. MnO 2 was chosen for decomposition of H 2 O 2 because of its low cost, low environmental impact, 29 high activity 30 and high stability in alkaline solutions 31 . Although MnO 2 has long been well known as a solid catalyst for H 2 O 2 decomposition, no studies have reported on the effect of H 2 O 2 decomposition by MnO 2 on iron chelate degradation in the alkaline Fenton system.…”

“…For a liquid monopropellant microthruster with catalytic ignition, silver (Ag) and platinum (Pt) are usually used as catalytic metals decompose the H 2 O 2 propellant. In addition, transition metal oxides also have been used as catalysts to decompose the H 2 O 2 propellant [61,62] due to their significant activities, in which pure and mixed manganese oxides are a major choice for H 2 O 2 decomposition [63,64]. Hitt et al [65] presented a H 2 O 2 microthruster in 2001, in which the silver catalytic pillars were adopted in a combustion chamber.…”
