“…Catalyst bed can initiate hydrogen peroxide decomposition in mono-propellant systems, and can inherit hypergolicity nature in bi-propellant systems. Heterogeneous catalysts including Nobel metals like silver (Ag), platinum (Pt), cobalt(Co) and transition metal oxides such as (CuO,MnO 2 , Mn 2 O 3 ) are the most common catalyst for space propulsion applications [3]. Catalyst should secure reasonable price cost, high activity, and long-life time.…”

Much effort has been devoted to replace pollutant, toxic, cancerogenic hydrazine-based propellants. Hydrogen peroxide could offer promising characteristics as well as high density specific impulse. Effective catalysts with high durability are required to initiate H2O2 decompositions, or to inherit hypergolic nature with different fuels. This study reports on the novel green synthesis of silver nanoparticles (18 nm) via hydrogen evolved by water electrolysis. MnO2 (20 nm) was developed in a sustainable manner via green hydrothermal processing. High crystalline, mono-dispersed particles were developed. Catalytic activity was assessed via precise measurements of liquid temperature profile (LTP) to reach the boiling point of hydrogen peroxide. Whereas silver demonstrated LTP peak at 20 seconds; MnO2 experienced LTP of 40 seconds. Catalyst survivability was recorded via precise measurement of life time mass loss rate upon catalyst addition to hydrogen peroxide. While silver nanocatalyst demonstrated high performance at the reaction start; silver was found to be poisoned with crystalline phase change to silver oxide within 20 seconds. On the other hand, manganese oxide experienced high durable catalytic action. Consequently, MnO2 could be candidate for H2O2 monopropellant thrusters as catalyst bed. On the other hand, silver nanoparticles could be candidate for a single use in bipropellant to inherit hypergolicity.

“…The promoter-in-fuel approach is one of the promising solutions to facilitate the hypergolic ignitions of ionic liquid–HTP bipropellants. Transition metal-containing promoters have the ability to catalyze the decomposition of HTP releasing a large amount of heat and highly reactive oxygen species, − which results in spontaneous autoignition of the promoter–fuel–oxidizer mixture. In recent years, some pioneering promoters, such as ferrocenyl iodocuprates, iodocuprate-containing ionic liquids/salts, , closo-icosahedral periodoborane salts, and energetic copper(II) complexes, , have been reported.…”

The emergence of tetrahydroborate (BH 4 − )/ cyanoborohydride (BH 3 CN − ) anion-based ionic liquid fuels in combination with high test peroxide (>90%H 2 O 2 , HTP) oxidizers has accelerated the greening of bipropellants. However, most BH 4 − and BH 3 CN − anion-based ionic liquids are sensitive to water, making it difficult to store them. Here, novel difunctional promoters are designed for hypergolic ignition of BH 4 − / BH 3 CN − anion-free ionic liquids with 90%H 2 O 2 . The transition metal in anions of promoters is expected to catalyze the exothermic decomposition of H 2 O 2 , and the substituted borohydride in cations of promoters acts as the ignition source. These novel difunctional promoters show good solubility in commercially available 1-allyl-3-methylimidazolium dicyanamide and 1-butyl-3methylimidazolium dicyanamide ionic liquid fuels, and the composite fuels exhibit high density, acceptable viscosity, and high thermostability. The addition of difunctional promoters ensures the smooth hypergolic ignition of BH 4 − /BH 3 CN − anion-free ionic liquid fuels with a minimum ignition delay time of 34.0 ms, and no apparent microexplosion and secondary combustion are observed during the ignition process. With the increase in the amount of the promoter, density specific impulses of the composite fuels improve gradually. This work provides a platform strategy for designing promoters by synergy of cations and anions and makes efforts to seek green bipropellants.

“…When the concentration of H 2 O 2 increases from 85 to 98%, the proportion of active oxygen changes from 40.0 to 46.1%, respectively, and the decomposition temperature increases from 907 to 1125 K in the same concentration range. The general requirements for a peroxide decomposition catalyst during the operation of such engines are detailed in a recent review [ 53 ]. The study highlights the minimum reaction start time after hydrogen peroxide makes contact with the catalyst, the high chemical stability of the process, the thermal and mechanical stability of the catalyst, among others.…”

Gaseous oxygen plays a vital role in driving the metabolism of living organisms and has multiple agricultural, medical, and technological applications. Different methods have been discovered to produce oxygen, including plants, oxygen concentrators and catalytic reactions. However, many such approaches are relatively expensive, involve challenges, complexities in post-production processes or generate undesired reaction products. Catalytic oxygen generation using hydrogen peroxide is one of the simplest and cleanest methods to produce oxygen in the required quantities. Chemically powered micro/nanomotors, capable of self-propulsion in liquid media, offer convenient and economic platforms for on-the-fly generation of gaseous oxygen on demand. Micromotors have opened up opportunities for controlled oxygen generation and transport under complex conditions, critical medical diagnostics and therapy. Mobile oxygen micro-carriers help better understand the energy transduction efficiencies of micro/nanoscopic active matter by careful selection of catalytic materials, fuel compositions and concentrations, catalyst surface curvatures and catalytic particle size, which opens avenues for controllable oxygen release on the level of a single catalytic microreactor. This review discusses various micro/nanomotor systems capable of functioning as mobile oxygen generators while highlighting their features, efficiencies and application potentials in different fields.
