The historicity and versatility of activated carbons (ACs) other carbon derivatives (OCDs) date back to antiquity. This article reviews the recent advances in synthesis, characterization, environmental applications these demand-driven adsorbents from biomass non-biomass sources. It first identifies relevant literature sources knowledge gaps then segmentalizes scrutinizes theme elucidate contemporary carbon-based adsorbents. Conventional advanced syntheses are highlighted. Current trends adsorbents' characterization remediation also presented. conventional AC synthesis includes one-step or two-step chemical physical activation a combinatorial two. Issues combinatorics examined. Advanced techniques such as hydrothermal carbonization/activation microwave-assisted irradiation described, which may involve procedures. OCDs, including nanotubes, nanofibers, dots, mainly employ syntheses, for example, nanotechnology. Currently, ACs OCDs characterized using like scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), nitrogen (N2) adsorption, X-ray diffraction (XRD), their structures, properties, potential efficacies. Their removing water, soil, air pollutants evaluated. highest percent removal efficiency was type-specific, reflecting precursor's nature, method, product quality. For instance, neem leaves by H3PO4 Fe nanoparticles tea extracts were 100% successful Pb2+ Cr6+, respectively, whereas rice husk produced 91.8% success Cr3+. However, differential adsorptivities metals moderate, with lowest. Due high cost, tedious processes producing restoring ACs, non-selectiveness, researchers continually search suitable alternatives, this review considers. Also, applying artificial intelligence (AI) advancing novel is discussed. Finally, future research dimensions proposed.

In this study, we present our findings from analyzing data contained in approximately 265,000 journal and patent publications the field of carbon nanotube (CNT)-related research spanning last two decades (2003 to 2023). The purpose study is identify extract prominent trends establish connections, such as those between materials applications. Using a natural language processing (NLP)-based analysis, have identified over 80 emerging concepts across three major categories (applications, materials, properties) CNTs, which presented "Trend Landscape" map. While early efforts appeared focus on synthesis techniques (including now well-established dominant technique chemical vapor deposition (CVD)), recent years has been driven by an increase interest CNT composites, especially involving other nanoscale MXene metal–organic frameworks (MOFs). High growth applications include use CNTs energy storage conversion technologies fuel cells, next-generation batteries, nanogenerators, sensors including wearable human motion sensors. Investment suggests commercial development variety industry types, semiconductors, energy, smaller extent biomedical industry. intent report serve useful guide researchers aid further exploration based

Carbon dots (CDs), a novel class of carbon-based nanoparticles, have received lot interest recently due to their exceptional mechanical, chemical, and fluorescent properties, as well excellent photostability biocompatibility. CDs' emission properties already found variety potential applications, in which bioimaging sensing are major highlights. It is widely acknowledged that fluorescence surface conditions closely linked. However, the structural complexity CDs, specific underlying process uncertain yet be explained. Because low toxicity, robust wide optical absorption, high chemical stability, rapid transfer characteristics, ease modification, CDs been recognized promising carbon nanomaterials for applications. Thus, following such outstanding they mixed imprinted onto different polymeric components achieve highly efficient nanocomposite with improved functional groups properties. Here, this review, various approaches techniques preparation polymer/CDs nanocomposites elaborated along individual characteristics CDs. CDs/polymer demanded sensor The insights from review detailed applications especially detection biological analytes metal ions, small organic molecules, several contaminants.
