Hydrogen Production from Ammonia Electrochemical Cracking

Advanced Science, EarlyView.
NH3 electrochemical cracking (e‐cracking) is a complementary technique to centralized thermal cracking for releasing H2 from NH3. In this article, we review recent advances in catalyst development for these cracking techniques and conduct a techno‐economic analysis (TEA) to evaluate the economic feasibility of e‐cracking.

Synergistic Charge Scavenging in Pt/C‐Polyoxometalate Systems for Scalable Biomass Power Generation via Super‐Reduced Electrolytes

Advanced Science, EarlyView.
Synergistic charge scavenging between Pt/C and liquid polyoxometalate mediators effectively dismantles the inherent biological recalcitrance of raw biowaste. This dynamic interfacial electron transfer unlocks a multi‐electron super‐reduced state (>4 electrons). By overcoming traditional electron‐harvesting ceilings, this approach enables scalable, high‐
