Enhanced hydroxylation and carbon dioxide uptake on nanotextured silver oxide

Nanotexturing of silver substrates with silver (I) oxide, Ag2O, is demonstrated using a one-step laser micro-machining process. Where ablation of the silver substrate took place, a highly textured nanoscale topography is generated. In contrast, a film-like oxide is formed next to the machined areas. Interestingly, it was observed that Ag2O formed within the laser tool path was significantly more reactive towards atmospheric H2O and CO2 compared …
