A deep understanding of defects is essential for the optimization of materials for solar energy
conversion. This is particularly true for metal oxide photo (electro) catalysts, which typically …

Generating charge carriers with lifetimes long enough to drive catalysis is a critical aspect for
photoelectrochemical and photocatalytic systems, and a key determinant of their efficiency …

The recently discovered phenomenon of broadband white-light emission at room
temperature in the (110) two-dimensional organic–inorganic perovskite (N-MEDA)[PbBr4](N …

Electrons are the workhorses of solar energy conversion. Conversion of the energy of light to
electricity in photovoltaics, or to energy-rich molecules (solar fuel) through photocatalytic …

The ultrafast light-activated electrocyclic ring-opening reaction of 1, 3-cyclohexadiene is a
fundamental prototype of photochemical pericyclic reactions. Generally, these reactions are …

Utilization of renewable energies for catalytically generating value-added chemicals is
highly desirable in this era of rising energy demands and climate change impacts. Artificial …

Small polaron formation is known to limit ground-state mobilities in metal oxide
photocatalysts. However, the role of small polaron formation in the photoexcited state and …

We review the tremendous advances in ultrafast X-ray science, over the past 15 years,
making the best use of new ultrashort X-ray sources including table-top or large-scale …

The transfer of charge at the molecular level plays a fundamental role in many areas of
chemistry, physics, biology and materials science. Today, more than 60 years after the …

Abstract Hematite (α-Fe2O3) is the most studied artificial oxygen-evolving photo-anode and
yet its efficiency limitations and their origin remain unknown. A sub-picosecond …
