Abstract: M–N–C catalysts with nitrogen‐coordinated metal single‐atom active sites have demonstrated high activity for hydrogen storage materials, but their stability in this application remains uncertain. This study addresses this issue by using nickel phthalocyanine (NiPc) molecules… read more here.

DOI: 10.1021/acsaem.8b01559
Abstract: Maximizing regeneration and minimizing recombination rates at dye–semiconductor interfaces is crucial for the realization of efficient dye-sensitized solar and photoelectrosynthesis cells. Previously it has been shown that simply coordinating the metal ion to the nonsurface… read more here.
