Surface/Interface Engineering of Carbon‐Based Materials for Constructing Multidimensional Functional Hybrids

Abstract

Carbonaceous materials (CMs), such as carbon nanotubes, fullerenes, graphene, carbon quantum dots, graphdiyne, and their derivatives, have sparked enormous excitement because of their attractive properties and great potential for solar energy conversion applications. Although pristine CMs are known for their unique electronic structure, optical properties, and thermal conductivity, many research fields and applications require functionalized CMs with integrated physicochemical properties and tunable dimensionality. Structurally modifying CMs through various surface/interface engineering reveals the numerous possibilities for tuning their architectures and properties. This Review mainly focuses on the basic surface/interface engineering issues of diverse CMs. The effects of surface/interfacial engineering in versatile systems as well as the excellent mechanical, electronic, optical properties and applications of the functionalized CMs‐based composites are highlighted. Some ongoing challenges and possible solutions for future exploration of CMs‐based functional composites are critically discussed.

Green and Near-Infrared Dual-Mode Afterglow of Carbon Dots and Their Applications for Confidential Information Readout

“…As a new type of luminescent nanocarbon materials, carbon dots (CDs) have attracted much attention and been widely applied in biotechnology, anti-counterfeiting, optoelectronic device, and photocatalysis areas in recent years due to possessing numerous superior features such as excellent photostability, chemical stability, biocompatibility, and cost-effective preparation [13][14][15][16][17][18][19][20]. More impressively, afterglow phenomena of CDs had also been discovered either through embedding them in certain matrices (e.g., poly(vinyl alcohol) (PVA), inorganic salts, urea/ biuret, zeolites, and silica) [21,22], or preparing specialstructured CDs by proper carbon precursors and reaction conditions [23,24].…”

Photocatalytic Synthesis of Oxidized Graphite Enabled by Grey TiO2 and Direct Formation of a Visible‐Light‐Active Titania/Graphene Oxide Nanocomposite

“…Graphene, a superstar in the materials field for quite some time, provides potential applications in hydrogen storage, supercapacitors, chemical and biosensors, catalysis, and so on. [1] Also graphene modification or functionalization provides derivatives that have been investigated at length for an even wider range of applications, [2] including photocatalysis [3][4][5] and comprehensive reviews [3,6,7] and applications focus on environmental remediation, [8][9][10] selective organic transformation, [11] hydrogen evolution, [12,13] CO 2 photoreduction, [14] sensing. [15][16][17][18] Moreover, other research directions include bioapplications (therapeutic delivery, biological imaging, cancer sensing), [19][20][21] various energy storage devices (such as fuel cells, microbial fuel cells, supercapacitors, electrochemical detection, dye synthesized solar cells), [22][23][24] or photoelectrochemical applications.…”

Facile diazonium modification of pomegranate peel biochar: A stupendous derived relationship between thermal and Raman analyses

“…Arylation of carbon allotropes is a very well established mean of preparing functional based carbon materials 1 for various applications comprising fillers 2 and reinforced polymeric matrices 3 , support of (electro) nanocatalysts 4 , flexible gas sensors 5,6 , electrode materials 7 , and photovoltaic applications 8 . Although graphene, carbon nanotubes, fullerene are advanced carbon based materials 9 , yet they are excessively expensive which limits the expansion of their utilization. Instead, one can take advantage of biochar(s) generated from the pyrolysis of agrowastes and other biomass resources 10,11 .…”
