“…In case of Ag/ SBA-15/TAEA, the electrocatalytic reduction occurs at slightly lower activity due to well-dispersed silver nanoparticles on branched TAEA amine. The decomposition of H 2 O 2 by silvercatalyst is similar to the reported mechanism 32 as represented in the equations 1 and 2.…”

Mesoporous SBA-15 was synthesized using tetraethylorthosilicate (TEOS) as the silica source and Pluronic (P123) as the structure-directing agent. The defective Si-OH groups present in SBA-15 were successively grafted with 3-chloropropyltrimethoxysilane (CPTMS) followed by tris-(2-aminoethyl) amine (TAEA) and/or tetraethylenepentamine (TEPA) for effective immobilization of silver nanoparticles. Grafting of TAEA and/or TEPA amine and immobilization of silver nanoparticles inside the channels of SBA-15 was verified by XRD, TEM, IR and BET techniques. The silver nanoparticles immobilized on TAEA and /or TEPA grafted SBA-15 was subjected for electrocatalytic reduction of hydrogen peroxide (H2O2). The TEPA stabilized silver nanoparticles show higher efficiency for reduction of H2O2 than that of TAEA, due to higher number of secondary amine groups present in TEPA. The amperometric analysis indicated that both the Ag/SBA-15/TAEA and Ag/SBA-15/TEPA modified electrodes required lower over-potential and hence possess high sensitivity towards the detection of H2O2. The reduction peak currents were linearly related to hydrogen peroxide concentration in the range between 3 × 10 -4 M and 2.5 × 10 -3 M with correlation coefficient of 0.997 and detection limit was 3 × 10 -4 M.

“…Therefore, the key technology of a monopropellant thruster is the catalyst, and consequently, numerous research groups on monopropellant thrusters have focused on catalysts, in terms of aspects such as * catalyst reactor design [2], catalyst reactivity and supports [3,19,21], catalyst additives [6,10,20], and catalyst poisoning [16]. In general, a monopropellant thruster is exposed to lowtemperature conditions because it is used mainly in space or a high-altitude environment.…”

“…Pirault-Roy et al 10 performed a wide experimental activity at the University of Poitiers, in collaboration with CNES, on the determination of the order of reaction of different catalyst materials and the study of the influence of stabilizing agents contained in commercial hydrogen peroxide on the catalytic activity. In this case, the catalyst with I the highest catalytic activity seemed to be silver, followed by manganese oxides and platinum.…”

Alta S.p.A. (Italy) and DELTACAT Ltd. (United Kingdom) are conducting a study, funded by the European Space Agency, into the development of hydrogen peroxide monopropellant thrusters using advanced catalytic beds. The present paper focuses on the design of a dedicated test bench to assess the effectiveness of different catalyst samples when immersed in hydrogen peroxide. To date, the apparatus has been used to study powdered silver and three oxides of manganese. The evaluation of an analytical technique for determining the observed decomposition rates is also presented. In addition to devising a quantitative method for assessing the efficacy of the candidate catalysts, some qualitative studies of proposed metallic catalysts, in the form of wires immersed in hydrogen peroxide, are also described. Of the catalyst materials tested so far, preliminary results suggest that dimanganese trioxide offers slightly better performance than both manganese dioxide and silver.
