Título: | A deprotection-free method for high-yield synthesis of graphdiyne powder with in situ formed CuO nanoparticles |

However, its broad application is greatly limited by the complicated multistep synthesis process including complex deprotection of hexakis-[(trimethylsilyl)ethynyl]benzene (HEB-TMS) and peeling of GDY from the substrates. Here, we describe a deprotection-free strategy to prepare GDY powder by directly using HEB-TMS as the monomer. When CuCl was used as the catalysts in DMF solvent, the yield of GDY powder reached ≈100 %. More interestingly, uniformly dispersed CuO nanoparticles with an average diameter of ≈2.9 nm were in situ formed on GDY after the reaction. The prepared CuO/GDY was demonstrated an excellent co-catalyst for photocatalytic hydrogen evolution, comparable to the state-of-art Pt co-catalyst. The deprotection-free approach will widen the use of GDY and facilitate its scaling up to industrial level. | Versión del editor: | https://doi.org/10.1002/anie.202210242 | URI: | http://hdl.handle.net/10261/287483 | DOI: | 10.1002/anie.202210242 | E-ISSN: | 1521-3773 |
