In photoelectrochemical cells, sunlight may be converted into chemical energy by splitting
water into hydrogen and oxygen molecules. Hematite (α-Fe2O3) is a promising photoanode …

The reactivity of mineral surfaces in the fundamental processes of adsorption, dissolution or
growth, and electron transfer is directly tied to their atomic structure. However, unraveling the …

The adsorption modes of H2O on a Fe-terminated hematite (0001) surface have been
investigated by first principles Density Functional theory within a periodic slab model and the …

Abstract The dominant growth planes (0 0 0 1) and (1 1 0 2) have been used to investigate
the activity of the natural α-Fe 2 O 3 in chemical-looping combustion system based on …

Single crystalline one-dimensional (1-D) SnO2 nanocrystals with controllable sizes,
including the diameter and the aspect ratio, were synthesized by modulating the precursor …

The interaction of absorbed water with defected hematite surfaces is studied in low-
coverage. Three point-defective surfaces, including an Fe-vacancy, an Fe-adatom site, and …

The natural pigment of hematite (red ocher, α-Fe 2 O 3) is coated homogenously with
colloidal silica-nanoparticles (SiNP) by a sol-gel process to obtain a durable hematite …

The surface chemical activity is a critical factor affecting the photocatalytic efficiency of
hematite. In this study, we investigate systematically the reaction kinetics of water heterolytic …

Stress-corrosion cracking of steel is a ubiquitous phenomenon in which steel is chemically
corroded, followed by fracture induced by applied loads. The products of steel corrosion in …

Abstract Electric potentials of the (0 0 1) surface of hematite were measured as a function of
pH and ionic strength in solutions of sodium nitrate and oxalic acid using the single-crystal …
