In order to differentiate with the previous approach (ilag), we term it as ionic liquidassisted grinding (ilag). our objectives were to determine whether ils have any role as grinding solvent when used in catalytic amount in mechanochemical grinding, and if they have a role, to determine how they affect the crystallization outcome.

Incipientwetness impregnation of the support, with aqueous solution of pdcl 2, h 2 ptcl 6 6h 2 o, agno 3, rucl 3, rhcl 3 precursors of appropriate concentrations (typically 1.0 mlg support). after a perfect mixing of the corresponding slurries, samples were dried under vacuum at room temperature for 12 h and then reduced in 5 h 2 ar at.

It can be seen that the increase of the catalytic activity in the line of samples gdfe 0.5 co 0.5 o 3 ˂ gdfe 0.2 co 0.8 o 3 ˂ gdcoo 3 that is in good agreement with h 2tpr, tpdo 2, and sta results. thus, the increase of the activity linearly correlated with the reaction ability and amount of βo 2 of perovskite for the corich sample. it.

Conditions;the use of 1 doubles the catalytic activity compared to the ligand reported in 2015.6,13 contrary to the catalyst itself,the ligand precursor 1 possesses an extremely low solubility in most solvents,and we were only able to dissolve it in chloroform and boiling able to account for this by grinding 1 into.

The introduction of ce 2 (so 4) 3 8h 2 o onto ceo 2 was realized by wet impregnation and solid grinding. the amount of so 4 2was calibrated by referring to the vapor sulfated catalyst (so 4 2ceo 2vs), which was pretreated under so 2 o 2 stream (200 mlmin, 100 ppm so 2 and 5 o 2, balanced with ar) at 100 c for 4 h.

An efficient 1,6conjugate addition of 3substituted indoles to paraquinone methides (pqms) using catalytic amount of bi(otf) 3 is described. this mild and atomeconomical protocol allowed us to access unsymmetrical diaryl(2indolyl)methanes in moderate to excellent yields under solventfree grinding conditions.

In order to study the catalytic performance of these co 3 o 4 catalysts for decomposition of ap, tga and dsc tests have been conducted and the results are shown in fig. the co 3 o 4 catalysts enhance the thermal decomposition of ap. tga and dsc curves demonstrate the stagnate decomposition period disappears and the t htd is decreased by more than 100 c compared to that.

As commented before, the conventional cza z5 catalyst prepared by grinding experienced a significantly higher relative loss of co conversion (26.7) than that obtained by the mixing method (16.7) despite the degree of copper sintering as well as the amount and nature of carbon deposits (table 3 and fig. s4 of supporting information) was.

2. partial substitution of cations as a strategy to enhance catalytic performance. perovskitetype oxides abo 3 can be properly modified by the partial substitution of atoms at a andor bsites, creating isostructural a 1x a x b 1y b y o 3 crystals (or aa'bb'o 3 for simplicity), which may stabilize unusual oxidation states of the b component, induce structural distortions and create cationic.
