PII.084 Nickel Single-Atoms Supported on Poly(Heptazine Imides): A Selective Transfer Hydrogen Photocatalyst Using Water as Proton Source

Resumo

Hydrogenation reactions of alkynes hold significant importance within the industrial chemical sector, and in connection to this, there is a strong interest in cost reduction for these processes. The harnessing of light as an energy source and the utilization of water as a proton source emerge as viable alternatives, offering cost reduction and an environmentally less aggressive. Here, poly(heptazine imides) stabilized with Ni Single-Atoms (Ni-PHI) were employed as catalysts in photocatalytic reactions to convert phenylacetylene into styrene. The test results demonstrated that Ni-PHI-2% achieved conversion rates and selectivity for styrene of 98.4% and 98.5%, respectively. Lastly, it was verified that the protons were donated by water.
