A review on functional nanoarchitectonics nanocomposites based on octahedral metal atom clusters (Nb ₆ , Mo ₆ , Ta ₆ , W ₆ , Re ₆ ): inorganic 0D and 2D powders and films

Abstract

This review is dedicated to various functional nanoarchitectonic nanocomposites based on molecular octahedral metal atom clusters (Nb 6 , Mo 6 , Ta 6 , W 6 , Re 6 ). Powder and film nanocomposites with two-dimensional, one-dimensional and zero dimensional morphologies are presented, as well as film matrixes from organic polymers to inorganic layered oxides. The high potential and synergetic effects of these nanocomposites for biotechnology applications, photovoltaic, solar control, catalytic, photonic and sensor applications is demonstrated. This review also provides a basic level of understanding how nanocomposites are characterized and processed using different technics and methods. The main objective of this review would be to provide guiding significance for the design of new high-performance nanocomposites based on transition metal atom clusters.

Nanoarchitectonics of Metal Atom Cluster‐Based Building Blocks Applied to the Engineering of Photoelectrodes for Solar Cells

“…The nanosized [{M 6 Q i 8 }L a 6 ] cluster units are particularly well suited for nanoarchitectonics as described earlier. [20,21] According to Ariga, [22] "the concept of nanoarchitectonics is supposed to involve the architecting of functional materials using nanoscale units based on the principles of nanotechnology". Thereby in recent years, the design of nanomaterials and surfaces integrating octahedral cluster-based units as functional building blocks [23][24][25][26][27][28][29] have become an intense field of research that nicely illustrates the concept of nanoarchitectonics.…”

From Solid-State Cluster Compounds to Functional PMMA-Based Composites with UV and NIR Blocking Properties, and Tuned Hues

“…The very rich properties of solid-state compounds based on [{Ta 6 Br i 12 }Br a 6 ] n− cluster building blocks and in particular, their absorption and redox properties are very interesting to be used as UV and NIR blockers and/or pigments to tune the hues of materials [ 28 , 48 , 61 ]. Indeed, {Ta 6 Br i 12 } 2+ core can be oxidized to {Ta 6 Br i 12 } 3+ and {Ta 6 Br i 12 } 4+ reversibly, with a specific absorption behavior for each oxidation state with colors going from green-emerald to red-brownish [ 28 , 49 , 50 , 51 ].…”

Materials Nanoarchitectonics for Advanced Physics Research

“…Many studies advocating nanoarchitectonics are related to the chemistry and bio-chemical fields. For example, in the areas of material creation, [90,91] structural control, [92,93] catalysis, [94,95] sensors, [96,97] basic bio-chemistry, [98,99] biomedical, [100,101] energy, [102,103] and environment. [104,105] However, since nanoarchitectonics is a method of architecting functional structures with a high degree of generality, it should have contributions that are independent of chemistry, physics, and biology.…”
