Why is Pd often "better" at C-H activation than Ni? Just published in JACS, we show that Pd acidifies C(sp3)-H bonds 100,000 times more than Ni. Our DFT collab with @tkschramm.bsky.social and Andreas Hansen @unibonn.bsky.social was crucial to explain acid-base rxns!

We have developed a metal-free electrocatalyst for rapidly and selectively generating hydrogen peroxide (HβOβ), a multi-ton commodity chemical. It operates through a novel H-atom transfer pathway to reduce O2.
