Metal-nitrogen-carbon (M-N-C) single-atom catalysts are a promising type of catalyst that could help provide cost-effective alternatives to platinum-based ones. However, there are still some aspects of their behavior that are misunderstood. To rectify this, a group of researchers delved into the intricacies of M-N-C catalysts, yielding promising results.

The properties of supramolecular polymers are dictated by the self-assembled state of the molecules. However, not much is known about the impact of morphologies on the properties of nano- and mesoscopic-scale polymeric assemblies. Recently, a research team demonstrated how terminus-free toroids and random coils derived from the same luminescent molecule show different photophysical properties. The team also presented a novel method for purifying the toroidal structure.

Nonthermal plasma (NTP) is used to activate CO2 molecules for hydrogenation into alternative fuels at low temperatures, also enabling the conversion of renewable electricity to chemical energy. Researchers from Tokyo Tech combined experimental and computational methods to investigate the hydrogenation pathway of NTP-promoted CO2 on the surface of Pd2Ga/SiO2 catalysts. The mechanistic insights from their study can help improve the efficiency of catalytic hydrogenation of CO2 and allows the engineers to design new concept catalysts.
