초록
We developed a highly dispersed Ru nanocatalyst (∼6 nm) via exsolution on BCZY, enabling high ammonia synthesis at 1 atm. TGA precisely quantified the exsolution degree (>96% at optimal conditions) and clarified that Ru nanoparticle formation proceeds through a strain-limited exsolution mechanism.
