Sulfide Perovskites for Solar Energy Conversion Applications Computational Screening...

One of the key challenges in photoelectrochemical water splitting is to identify efficient semiconductors with band gaps of the order of B2 eV to operate as the large-band...

17 NOV

Towards identifying the active sites on RuO2(110) in catalyzing oxygen evolution...

While the surface atomic structure of RuO 2 has been well studied in ultra high vacuum, much less is known about the interaction between water and RuO 2 in aqueous...

Deactivating Carbon Formation on a Ni Al2O3 Catalyst under Methanation Conditions

The carbon formation causing deactivation during CO methanation was studied for a Ni/Al 2 O 3 catalyst. Sulfur-free methanation at low temperature (573 K) for various...

17 JUL

Bottom-Up Design of a Copper-Ruthenium Nanoparticulate Catalyst for Low-Temperature...

A novel nanoparticulate catalyst of copper (Cu) and ruthenium (Ru) was designed for low-temperature ammonia oxidation at near-stoichiometric mixtures using a bottom-up...

27 JUN

Ammonia synthesis from N2 and H2O using a lithium cycling electrification strategy...

Ammonia production is imperative to providing food for a growing world population. However, the primary method of synthetic ammonia production, the Haber Bosch process...

Strategies for stable water splitting via protected photoelectrodes

Photoelectrochemical (PEC) solar-fuel conversion is a promising approach to provide clean and storable fuel (e.g., hydrogen and methanol) directly from sunlight, water...

01 FEB

Interface band gap narrowing behind open circuit voltage losses in Cu2ZnSnS4 solar...

We present evidence that bandgap narrowing at the heterointerface may be a major cause of the large open circuit voltage deficit of Cu2ZnSnS4/CdS solar cells. Bandgap narrowing...

20 JAN

Operando investigation of Au-MnOx thin films with improved activity for the oxygen...

The electrochemical splitting of water holds great potential as a method for producing clean fuels by storing electricity from intermittent energy sources. The efficiency...
