چکیده

Mesoporous polyacrylamides (PAMs) with tunable porosities were synthesized in 1-alkyl-3-methylimidazolium tetrafluoroborates ([Cnmim][BF4], n = 4, 6, 8, 10). The as-synthesized PAM was used as a support for Pd nanoparticles and the Pd/PAM composite showed high catalytic activity and selectivity for the hydrogenation of p-chloronitrobenzene reaction to yield p-chloroaniline.

Synthesis, characterization and photocatalytic activity of CeO2-SBA-15

Mesoporous photocatalysts of CeO2/SBA-15 are prepared by two methods of direct synthesis as solvent-usage and solvent-free methods. In solvent-usage method, CeO2/SBA-15 is synthesized in acidic media. While, in solvent-free method, CeO2/SBA-15, has been prepared through the novel path of directly grind cerium salt into the as-prepared samples of SBA-15 occluded ...
