In recent years, many theoretical and experimental studies have been carried out to develop one of the most interesting aspects of the science and nanotechnology which is called carbon-related nanomaterials. The goal of this paper is to provide a review of some of the most exciting and important developments in the synthesis, properties, and applications of low-dimensional carbon nanomaterials. Carbon nanomaterials are formed in various structural features using several different processing methods. The synthesis techniques used to produce specific kinds of low-dimensional carbon nanomaterials such as zero-dimensional carbon nanomaterials (including fullerene, carbon-encapsulated metal nanoparticles, nanodiamond, and onion-like carbons), one-dimensional carbon nanomaterials (including carbon nanofibers and carbon nanotubes), and two-dimensional carbon nanomaterials (including graphene and carbon nanowalls) are discussed in this paper. Subsequently, the paper deals with an overview of the properties of the mainly important products as well as some important applications and the future outlooks of these advanced nanomaterials.

Nanomaterials are becoming important materials in several fields and industries thanks to their very reduced size and shape-related features. Scientists think that nanoparticles and nanostructured materials originated during the Big Bang process from meteorites leading to the formation of the universe and Earth. Since 1990, the term nanotechnology became very popular due to advances in imaging technologies that paved the way to specific industrial applications. Currently, nanoparticles and nanostructured materials are synthesized on a large scale and are indispensable for many industries. This fact fosters and supports research in biochemistry, biophysics, and biochemical engineering applications. Recently, nanotechnology has been combined with other sciences to fabricate new forms of nanomaterials that could be used, for instance, for diagnostic tools, drug delivery systems, energy generation/storage, environmental remediation as well as agriculture and food processing. In contrast with traditional materials, specific features can be integrated into nanoparticles, nanostructures, and nanosystems by simply modifying their scale, shape, and composition. This article first summarizes the history of nanomaterials and nanotechnology. Followed by the progress that led to improved synthesis processes to produce different nanoparticles and nanostructures characterized by specific features. The content finally presents various origins and sources of nanomaterials, synthesis strategies, their toxicity, risks, regulations, and self-aggregation.

Phase-pure brookite TiO2 and its activity has been obscured for its difficulty of synthesis. Hence, we introduced the method of preparation and property of phase-pure brookite TiO2 and prepared phase-pure brookite TiO2 by hydrothermal method using Ti(SO4)2 as precursor. Phase formation was achieved by hydrothermal treatment at 180 °C after different synthesis time. The physical and photophysical properties of samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), UV–vis diffraction (UV–vis/DRS), and Raman spectroscopy. The dependence of the photocatalytic activities on synthesis time and correlations with the physical properties of brookite samples was examined in detail. In the case of mineralization of rhodamine B (Rh B), the sample with the narrowest bandgap and the lowest photoluminescence (PL) intensity (at hydrothermal synthesis time 36 h) showed the best photodecolorization activity. Proposed decolorization mechanism was elucidated in the light of the UV–vis spectra of the analyzed degradation products and frontier electron density (FED) theory. The results indicated that photocatalytic decolorization by brookite TiO2 is a highly effective way to remove Rh B under near-visible light irradiation.
