Catalytic activity of rare earth phosphates for SF6 decomposition and promotion effects of rare earths added into AlPO4

Metal Phosphate-Supported Pt Catalysts for CO Oxidation

“…In the literature, some metal carbonates, phosphates, and sulfates have been used as supports to load metals [2]. From the examples on the catalytic applications of metal phosphate-based catalysts cited in the Introduction section [4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,…”

“…In a classic book written by Tanabe, Misono, Ono, and Hattori, metal phosphates are highlighted as a new family of solid acids showing some promising applications in heterogeneous catalysis [3]. Metal phosphates can be used as catalysts directly, for instance, in the partial oxidation of propane [4], oxidative dehydrogenation of isobutane to isobutene [5,6,7], oxidative dehydrogenation of ethylbenzene to styrene [8], dehydration of cyclohexanol and 1-methylcyclohexanol [9,10,11], retro-Prins reaction [12,13], terpene rearrangements [14], alkylation of anisole with alcohols [15], dehydrofluorination of CF 3 CH 3 into CF 2 CH 2 [16,17], hydrolysis of CCl 2 F 2 [18,19,20], decomposition of CF 4 [21,22], decomposition of CH 2 FCF 3 [23], decomposition of chlorobenzene [24], decomposition of SF 6 [25,26], and hydrolysis of NF 3 [27]. …”

Separation of SF6 from SF6/N2 mixture using metal–organic framework MIL-100(Fe) granule

“…For the recovery or the decomposition of SF 6 , several technologies have been used such as cryogenic distillation, membrane separation [7,8], plasma decomposition [9][10][11], catalyst decomposition [12], high temperature decomposition [9], and adsorption http://dx.doi.org/10.1016/j.cej.2014.09.123 1385-8947/Ó 2014 Elsevier B.V.

Construction and evaluation of a modular biofilm-forming chamber for microbial recovery of neodymium and semi-continuous biofilm preparation. Tolerance of Serratia sp.N14 on acidic conditions and neutralized aqua regia

“…[57] RePO 4 has also been reported for the encapsulation and permanent disposal of radioactive wastes (U 4 + ,Th 4+ ) [58] as well as for applications in bioimaging [59] fluorescent coatings, due to the bulk properties of lanthanum phosphates, [60] as phosphors [61] or as catalyst hosts. [62] Lanthanide orthophosphates, due to their specific properties (very low solubility in water, high thermal stability, high index of refraction and for the case of Nd and Eu, high concentrations of lasing ions) they can be used for such applications as sensors, phosphors, catalysts, heat-resistant materials, ceramic materials and proton conductors. [63] In particular NdPO 4 has been found to have applications in laser physics, [58,64] on the photoluminescence of Nd 3+ in potassium titanyl phosphate (KTiOPO 4 or KTP) crystals and in ceramic materials.…”
