Blue-LED activated photocatalytic hydrogenation of nitroarenes with CuO/CuO heterojunctions.

This study describes how the optimization of CuO/CuO heterostructures can enhance their (photo)catalytic performance. More specifically, the evaluation of catalysts with different CuO/CuO molar ratios was used to optimize their performance for the hydrogenation of 4-nitrophenol under both blue-LED light and dark conditions. For the first time, we analyzed the effect of blue LED irradiation on this reaction and found that when blue LEDs are used as the light source, a CuO/CuO ratio of 0.

Non-covalent Functionalization of Graphene to Tune Its Band Gap and Stabilize Metal Nanoparticles on Its Surface.

Controlling graphene conductivity is crucial for its potential applications. With this focus, this paper shows the effect of the non-covalent bonding of a pyrimidine derivative (HIS) on the electronic properties of graphene (G). Several G-HIS hybrids are prepared through mild treatments keeping unaltered the structures of both G and HIS.
