Description
Paulina Wira and eleven colleagues watch a surface catalyst wake up under voltage. Their platform is a metal-organic framework laid on gold, meant to split water for hydrogen. Catalyst papers often treat such frames as fixed, yet electric bias can rebuild them on the spot.
Live microscopy showed the frame's neat chains, frozen at rest, loosen under negative bias. Gold atoms lift out and return in a cycle, leaving many undercoordinated sites. Computer models say the inner gold nodes are inert, while the new edge sites and gaps bind hydrogen almost perfectly. That balance is the sweet spot for hydrogen release. The authors propose designing catalysts that transform on purpose.
