Atoms and molecules make up all of the different substances, including solids ... Ask students to use the Snap Cubes to make an acetic acid molecule. Then show students the animated Snap Cube model of ...

to acetic acid (CH 3 COOH) using a nano-heterostructure catalyst. This catalyst features Rh-Zn atomic-pair dual sites confined within a MoS 2 lattice, integrated with TiO 2 nanoparticles.

By varying the size of tin used from single atoms to ultrasmall clusters and also to larger nano-crystallites, the team could control the CO 2 conversion to acetic acid, ethanol and formic acid ...
