2D semiconductor nanosheets for solar photocatalysis

EcoEnergy, Journal Year: 2023, Volume and Issue: 1(2), P. 248 - 295

Published: Dec. 1, 2023

Abstract In the advancing world of graphene, highly anisotropic 2D semiconductor nanosheets, notable for their nanometer‐scale thickness, have emerged as a leading innovation, displaying immense potential in exploration renewable and clean energy production. These garnered significant attention from researchers. The nanosheets are marked by extraordinary electronic, optical, chemical attributes, positioning them attractive foundational components heterogeneous photocatalysts. This review diligently summarizes both seminal work ongoing developments pertaining to application solar within context photocatalysis. We begin detailing distinctive properties concentrating on pivotal roles augmenting photocatalytic efficiency, explaining intrinsic mechanisms that govern migration rate photogenerated carriers material's surface. Subsequently, we delineate methods employed synthesize typical nanosheets. alignment with overarching objective expanding light absorption capacity accelerating charge transfer, also examine current research hybridization techniques involving materials varied dimensions, well deployment diverse applications. conclude identifying promising avenues challenges await further this burgeoning field.

Photoelectron spectroscopy of ceria: Reduction, quantification and the myth of the vacancy peak in XPS analysis

Surface and Interface Analysis, Journal Year: 2023, Volume and Issue: 55(11), P. 845 - 850

Published: Sept. 4, 2023

Primarily due to its inherent redox chemistry, ceria (CeO 2 ) is of use in many diverse areas research. However, there a wealth misinterpretation the oxygen spectra when discussing result damage or reduction CeO lattice, especially with regard signal this region attributed vacancies. In paper, it shown that peak cannot be vacancies and better understanding changes stoichiometry best viewed from Ce(III) component considered tandem O 1s signal.
