TL;DR: In this article , a cascade synergistic catalysis strategy by atomic and low-coordinated cluster Pt on well-defined Cu-CuZrO x , which involves enhanced C-H activation on atomic Pt 1 and O-H insertion and activation on cluster Pt n in the oxidation of glycerol to glyceraldehyde, and cluster P n for C=O activation followed by O-C insertion and atomic P 1 for C-C activation in the tandem oxidation of glyceral dehyde to glyceric acid, was proposed.
Adsorption of Malachite Green by Diatomite: Equilibrium Isotherms and Kinetic Studies
TL;DR: In this paper, the utilization of diatomite as potential adsorbent to remove malachite green (MG) from aqueous solution was developed, which was evaluated by scanning electron microscope (SEM) and Brurauer Emmerr Teller (BET).

Immobilizing Laccase on Modified Cellulose/CF Beads to Degrade Chlorinated Biphenyl in Wastewater.
TL;DR: MCCBs, as a new type of green-based support, are very promising in material immobilizing laccase, which may be of potential advantage for the removal of polychlorinated biphenyls in wastewater from an environmental point of view.
