formation of strontium oxide (SrO). A review on the literature of the thermal behavior of inorganic oxalates reveals that except yttrium oxalate, all undergo thermal decomposition before melting and the decomposition kinetics is not complicated except in the

[ 24 ] ( Fig. 1 ), two ionic liquids BMImBF 4 and BMImBF 6 [ 25 ] ( Fig. 2 ) were synthesized according to the literature procedure. Fig. 1 The structure of Jacobsen's catalyst

where the Au particles exhibit a pseudo-spherical morphology, suggesting a small area of contact at the interface between the metal crystallites and the TiO 2 support. This is in agreement with published literature [ 31 ] demonstrating that Au/TiO 2

explained as follows. During the preparation of the supported catalyst, tungstic acid, H 2 O 2 and H 3 PO 4 were first mixed according to the ratio in the literature [ 4 ] in order to get the active species of [(PO 4 ){WO(O 2 ) 2 } 4 ] 3− . Second, the

ranging from 5 to 60 °C ( Table 2 ). A literature review revealed that typical E a values for mass transport controlled aqueous chemical reactions are 10–20 kJ/mol [ 36 , 37 ]. Because the activation energy value for 1% Mg/Cu was within this range, the

literature. Additionally, copper (Cu) species have been known to have the ability to catalyze the amination of aromatics in electrochemical processes [ 23 ]. More recently, Parida et al. [ 20 ] reported that a Cu-amine modified MCM-41 catalyst also showed

silicotungstates, and studies on the lacunary phosphotungstates [ 29 – 32 ] are very scarce. A literature survey shows that studies on heterogeneous lacunary phosphotungstates are very scarce. To the best of our knowledge, only one report on the catalytic

derivative rather than the acridinone derivative. The kinetic data are presented in Table 1 . The dependence of the absorbance with time is first order with respect to [TCA] ( Fig. 1 ). The oxidation process is known in the literature to proceed

samples calcined at 400 and 500 °C exhibit very broad peaks due to amorphous state, with only a little of anatase phase in the sample calcined at 500 °C. According to the literature data [ 13 , 15 ], this result means that the addition of a small amount

. Literature reports show several different views about the effect of pH on dye adsorption [ 27 ]. Bilgic [ 28 ] reported that a change in pH of MB solutions has no significant effect on the adsorption of MB within bentonite [ 29 ]. Ghosh and Bhattacharyya [ 29
