Chemical bond conversion directly drives power generation on the surface of graphdiyne

•The interaction between graphdiyne (GDY) and H2O was found to generate electricity •The chemical bond conversion causes electron transfer between GDY and H2O molecules •Other similar molecules have also been shown to generate electricity in this way Clean, infinitely renewable energy sources with low maintenance requirements that are not subject to geographical restrictions will be an important solution to energy shortages and environmental pollution. The conversion of material has been highly scrutinized by scientists, especially the discovery of some new concepts, new phenomena, and new sciences. We describe here an original discovery from graphdiyne (GDY) material. The conversion of acetylenic bonds with the intervention of H2O molecules generates a collectable induced electricity with an output voltage of 58 mV and a current of up to 203 nA cm2, illustrating an exceptional concept. We demonstrate multiple systems, such as using ammonia and hydrochloride gases to replace moisture, finding that GDY films can generate respectable induced electricity. This unique electrical phenomenon originating from chemical bond conversion potentially provides an unexplored area for new energy research, helping us to better understand the essence of power generation.
