Controllable synthesis of porous silver cyanamide nanocrystals with tunable morphologies for selective photocatalytic CO reduction into CH.

The conversion of CO driven by solar energy into carbon-containing fuel has huge potential applications. However, most photocatalysts can only promote the two-electron reduction process to generate CO, and it is difficult to produce eight-electron CH, which is more valuable and can store more solar energy. Herein, we prepared porous silver cyanamide nanocrystals with tunable morphologies via a facile synthesis strategy.
