Front cover image: Identification of the reaction sites though atomic-level perspective is significant for designing highly efficient CO2 reduction photocatalysts. In article number 10.1002/cey2.264, Wang and co-workers report a desirable sulfidation strategy over an Aurivillius-related photocatalyst Bi2O2SiO3, which facilitate local charge separation, contributing to enhanced rate selectivity....

The need for environmental resistance is a critical material barrier to the operation of fossil systems with the improved energy efficiencies and emissions performance described by the goals of the Vision 21 concept of the U.S. Department of Energy’s Office of Fossil Energy. All fossil fuel-derived processes contain reactive species and high-temperature degradation arising from reactions of sol...

One of the ways to improve activity sulfide catalysts is increase quantity molybdenum up contents greater than 15 wt%. For such high Mo contents, distribution MoS2 particles suspected play an important role in catalytic activity. A complete description active phase thus required and implies measuring i) size stacking isolated slabs, ii) proportion involved aggregates or individual iii) aggregat...
