Abstract
Mesoporous nanomaterials are considered advanced functional materials because of their large specific surface area and short charge transfer distance. Herein, CdS nanoparticles with a mesoporous structure (CdS MNPs) were prepared using an in situ templating method. CdS/Cd–Cys hybrid nanoparticles were converted to CdS MNPs through sulfidation. X-ray photoelectron spectroscopy data demonstrated that CdS MNPs were formed through anion exchange. Due to enhanced light absorption and a larger specific surface area, CdS MNPs exhibited a 2.6 times higher photocatalytic rate than CdS nanoparticles. The proposed strategy for the synthesis of CdS MNPs is helpful for fabricating sophisticated nanostructures.
期刊介绍：
Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage.
Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
