“…In addition, unsuitable solvents also lead to phase transformation of Pe-CQDs from alpha-phase to delta-phase, affecting structural stability . Therefore, it is a key factor to use appropriate solvents during purification to maintain structural stability of Pe-CQDs. ,, Luther’s group demonstrated an improved synthesis route and purification method for CsPbI 3 Pe-CQDs using methyl acetate as an antisolvent that properly removes surface species. The study showed that purified Pe-CQDs maintained their cubic shape and phase stability in ambient air and at extremely low temperatures for several months.…”

Perovskite colloidal quantum dots (Pe-CQDs) are promising materials for the next-generation optoelectronic devices due to their outstanding material properties derived from perovskites and QDs. Among the various synthesis methods, the hot injection (HI) method has been mainly used to fabricate the active layer of photovoltaics. For the effective application of Pe-CQDs, the synthesis variables that determine the properties of Pe-CQDs should be determined. The variables of Pe-CQDs synthesis can be divided into two types. First, the crystal nucleation and growth rates can be physically modified by reaction time and temperature. Second, the synthesis mechanism can be chemically modified by adjusting the precursors and injection type. In this review, various HI-based strategies are systematically classified and investigated. Furthermore, we discuss on how Pe-CQDs with enhanced properties prepared by advanced synthesis strategies affect the power conversion efficiency and stability of photovoltaics. Finally, the current limitations of Pe-CQD synthesis and future agendas are presented.

“…Despite substantial progress in the synthesis and characterization of 2D TMOs, their current applications are mostly focused on energy storage, energy conversion, catalysis, and electronics [20][21][22]. There is no prior research on the use of 2D TMOs for solid lubrication.…”

Beyond conventional 2D layered materials such as graphene and transition metal dichalcogenides, 2D metal oxides have also received much interest in recent years. They have unique electronic (such as 2D TiO2 and MoO2), catalytic (such as 2D CeO2 and MnO2), and magnetic properties (such as 2D Fe2O3) compared with bulk metal oxides due to their atomically thin structures. Certain types of 2D metal oxides also have the potential to be a new type of high-performance solid lubricants due to the tunable interlayer interaction and possibility for 2D heterostructure formation, but this remains largely unexplored. In this work, we developed a scalable microwave-assisted solid-state synthesis of 2D Fe2O3 and their nanocomposites with reduced graphene oxide (rGO). The 2D Fe2O3/rGO nanocomposites were systematically characterized by electron microscopies and spectroscopies, and their utilization as solid lubricants was studied by pin-on-disk tribometer on both silicon and steel substrates. The results show that due to the easy sliding between 2D Fe2O3 and rGO nanosheets and their unique magnetic-induced assembled morphology, low coefficient of friction (COF) can be achieved for both steel-silicon and steel-steel interfaces. Superlubricity (COF ∼ 0.007) can be achieved for the 2D Fe2O3/rGO nanocomposite with a GO primer layer on a steel substrate. This work provides new insights into the development of functional 2D nanocomposites and expands their applications to solid lubrication and beyond.
