Selective hydrogenation of nitroarenes using an electrogenerated polyoxometalate redox mediator.

Catalyst Development for Selective Hydrogenation of Functionalized Alkynes and Nitroarenes

Carbon supported Pt colloid as effective catalyst for selective hydrogenation of nitroarenes to arylhydroxylamines.

The Pt colloid supported on carbon is an active and selective catalyst for the partial hydrogenation of nitroaromatics with electron-withdrawing substituents to the corresponding N-arylhydroxylamine, indicating an additive-free green catalytic approach for arylhydroxylamine synthesis.

A sulfonated poly(arylene ether ketone)/polyoxometalate-graphene oxide composite: a highly ion selective membrane for all vanadium redox flow batteries.

A highly ion-selective membrane for vanadium redox flow batteries (VRBs) consisting of sulfonated poly(arylene ether ketone) (SPAEK) and polyoxometalate coupled with a graphene oxide was designed and fabricated. The SPAEK/PW-mGO composite membrane showed an effectively low self-discharge rate and excellent Coulombic efficiency (98.73%) in VRBs.

Nanopalladium on Amino-functionalized Mesocellular Foam as an Efficient and Recyclable Catalyst for the Selective Transfer Hydrogenation of Nitroarenes to Anilines

Herein, we report on the use of nanopalladium on amino-functionalized siliceous mesocellular foam as an efficient heterogeneous catalyst for the transfer hydrogenation of nitroarenes to anilines. In all cases, the protocol proved to be highly selective favoring the formation of the desired aniline as the single product in high yields with short reaction times, when employing the naturally-occur...

Polyoxometalate supported complexes as effective electron-transfer mediators in dye-sensitized solar cells.

Two Anderson-type heteropolyanion-supported copper phenanthroline redox couples have been successfully introduced into dye-sensitized solar cells, which can significantly increase the short-circuit photocurrent, open-circuit voltage and the conversion efficiency by 2.2 times, 26.8% and 3.93 times respectively, compared to the pristine copper phenanthroline redox couple.
