“…(b) The induced decrease in the surface area of 0.045FeAlO sample due to increasing the amount of Fe 2 O 3 loading from 4.5 to 6.5 mol % may be ascribed to the aggregation of small iron species into larger bulk particles of iron in preparation process [42]. (c) The slight increase in S BET value due to Ag 2 O-doping precalcined at 500˚C can be attributed to creation of new pores due to liberation of nitrogen oxides gases during the thermal decomposition of AgNO 3 dopant added [43]. (d) The observed significant decrease in S BET of the investigated samples as result of increasing the calcination temperature from 500 to 800˚C could be attributed to the sintering process.…”

In this paper, we aimed to investigate the influence of extent of Fe 2 O 3 loading, Ag-doping and precalcination temperature of the Fe 2 O 3 / Al 2 O 3 system on its physicochemical, surface and catalytic properties. The techniques employed were TG/DTG, XRD, nitrogen adsorption at −196˚C and the catalytic decomposition of H 2 O 2 at 25-40˚C. Material and Methods Aluminum hydroxide sample was prepared by precipitating Al(NO 3) 3 •9H 2 O (1M) solution using 0.2M ammonia solution at 70˚C

“…The interaction between the support and transition metal oxides can take place via the formation of metal aluminate in case of alumina support, or solid solution in case of MgO support [3,4] that having small catalytic activity if compared to metal oxide-supported solid. For this reason it is important to study the possibility of obtaining membranes which can not react with the catalytically active phase (transition metal oxide) and with low cost to be economic.…”

“…The catalytic activity and selectivity of the oxide catalyst can be modified by loading on different support materials [5,6]. The interaction between the support and transition metal oxide can take place via of formation metal aluminate in case of alumina-support, or solid solution in case of MgO support [7,8] having small catalytic activity if compared to metal oxide-supported solid. For this reason it is important to study the possibility of obtaining membranes which can not react with the catalytically active phase (transition metal oxide) and with low cost to be economic.…”

A commercial cordierite sample showed a small catalytic activity in isopropanol conversion carried out at 150-350 ºC and no measurable activity in CO oxidation by O 2. On the other hand, supporting NiO on Al 2 O 3-modified cordierite resulted in the formation of an active solid that having good catalytic activity in isopropanol conversion and CO oxidation by O 2. These two reactions were carried out at 150-350 and 200 ºC, respectively. The results revealed that the catalyst containing 5% (w/w) NiO showed the highest activity in the alcohol conversion and acted as selective dehydration catalyst. The catalyst sample containing 20% NiO (w/w) exhibited a good activity in CO oxidation by O 2 which decreased progressively by increasing its calcination temperature within 350-600 ºC. Al 2 O 3-treated cordierite dissolved a portion of NiO in its lattice, increasing the calcination temperature within 350-600 ºC increases the dissolution of NiO in the matrix of Al 2 O 3-modified cordierite system.
