Plasma Catalytic Removal of Hexanal over Co–Mn Solid Solution: Effect of Preparation Method and Synergistic Reaction of Ozone
Removal of hexanal via a post-plasma
catalysis system over a Co–Mn
solid solution at ambient temperature and pressure was investigated
in this study. Results showed that CoMnÂ(9/1) prepared by a citric
acid method exhibited the best catalytic activity, which could be
ascribed to the higher redox property. Moreover, the coprecipitation
method was applied and improved CO<sub>2</sub> selectivity significantly,
which could be due to smaller grain size, larger surface area, and
higher oxygen storage capacity. The reaction pathway and intermediates
were analyzed by in situ Fourier transfrom infrared spectroscopy.
In addition, results indicated that the removal of hexanal included
direct decomposition by plasma and further oxidation of intermediates
on the catalyst surface. Furthermore, it could be inferred that the
intermediates were further oxidized by the synergistic effect between
active oxygen species and catalyst and that the utilization of ozone
was the key point in the process
The Application of Y Series Acceptor-Based Double-Cable Polymers in Single-Material Organic Solar Cells
The
development of efficient and stable organic photovoltaic (OPV)
systems for commercial applications has long been a primary objective.
While single-component material systems have demonstrated promising
operational and thermal stability, their efficiency still lags behind
that of multicomponent bulk heterojunction devices due to limitations
in scarce building blocks, complex synthesis processes, and challenges
in controlling morphology. In this work, we present a novel approach
by introducing a fused-ring electron acceptor as a pendant segment,
which offers new possibilities for the development of double-cable
single-component copolymers. This innovative strategy not only broadens
their spectral absorption but also simplifies their synthesis complexity.
Through careful adjustment of molecular weight, we achieved an outstanding
power conversion efficiency of 9.35% and a minimized energy loss of
0.517 eV, which is one of the best results reported for structure
well-defined double-cable copolymer-based OPVs. Impressively, the
designed double-cable polymers exhibit excellent photo, thermal, and
mechanical stabilities, further highlighting their potential for practical
applications
