An Optically Transparent Iron Nickel Oxide Catalyst for Solar Water Splitting

Xile Hu, Aswani Yella, Matthew Thomas Mayer, Stanley David Tilley, Carlos Gilberto Morales Guio

Sunlight-driven water splitting to produce hydrogen fuel is an attractive method for renewable energy conversion. Tandem photoelectrochemical water splitting devices utilize two photoabsorbers to harvest the sunlight and drive the water splitting reaction. ...

Widely available active sites on Ni2P for electrochemical hydrogen evolution - insights from first principles calculations

Xile Hu, Lucas-Alexandre Stern, Ligang Feng, Martin Hangaard Hansen

We present insights into the mechanism and the active site for hydrogen evolution on nickel phosphide (Ni2P). Ni2P was recently discovered to be a very active non-precious hydrogen evolution catalyst. Current literature attributes the activity of Ni2P to a ...

Direct Light-Driven Water Oxidation by a Ladder-Type Conjugated Polymer Photoanode

Kevin Sivula, Nestor Guijarro Carratala, Xiaoyun Yu, Mathieu Steven Prévot, Pauline Bornoz

A conjugated polymer known for high stability (poly[benzimidazobenzophenanthroline], coded as BBL) is examined as a photoanode for direct solar water oxidation. In aqueous electrolyte with a sacrificial hole acceptor (SO32-), photoelectrodes show a morphol ...
