In this work, a new platinum (Pt) nanoparticles-functionalized poly(diallyl dimethyl ammonium chloride) (PDDA)-diamond powder (DMP) composite-modified glassy carbon electrode (GCE) was fabricated for electrochemical sensing of the selective or simultaneous determination of bisphenol A (BPA) and bisphenol S (BPS). The Pt/PDDA-DMP hybrid was characterized by Scanning electron microscopy, Transmission electron microscope, Fourier transform infrared, X-ray diffraction analyzer. This hybrid exhibited remarkable electrocatalytic activity towards the oxidation of BPA and BPS. The simultaneous determination of BPA and BPS by cyclic voltammetry yielded a difference of 0.316 V, which was sufficiently large for their potential recognition and simultaneous detection in mixtures. Differential pulse voltammetry was successfully used to simultaneously quantify BPA and BPS within the concentration range of 5-30 and 10-60 μM under optimal conditions, respectively. The detection limits (S/N = 3) of Pt/PDDA-DMP/GCE for BPA and BPS were 0.6 and 2.0 μM, respectively. The fabricated electrode showed good sensitivity, stability, and selectivity. The proposed method was successfully applied to determine BPA and BPS in biological samples. Bisphenol A (BPA) [2,2-bis (4-hydroxyphenyl) propane (C 15 H 16 O 2 )] is an important chemical raw material that is widely used in industrial production and daily life.1-3 It is extensively used in food cans, packing materials, water bottles, and baby bottles. As an environmental hormone material that causes abnormal hormone activity, BPA causes irreversible damage to organisms and the environment, and low doses can even result in human endocrine disorders. 5,6 In addition, BPA negatively affects female hormones, which can lead to a series of female diseases, such as induced precocious puberty, reproductive dysfunction, endometrial hyperplasia, and recurrent miscarriage. 7,8 Canada and China banned the use of BPA in baby bottles in 2010 and 2011, respectively, because of its negative effects on humans, particularly to children and infants. 9 In recent years, numerous companies and factories are currently using bisphenol S (BPS) [4,4 sulfomyldiphenol (C 12 H 10 O 4 S)] instead of BPA.10 BPS is widely used in polyethersulfone. The production and use of BPS as a chemical additive in pesticides, dyestuffs, colorfast agents, dye dispersants, and monomer in cyclic carbonates are increasing and will exceed those of BPA. 11,12 Although BPS has high thermal stability and low biodegradability, 13 it also has biological toxicity 14,15 and negative hormone effects.16,17 BPS and BPA disrupt the human endocrine system by interfering with several functional nuclear receptors.18 Thus, BPS is not a safe and reliable replacement for BPA. Several methods are available for state of the art tools for detecting BPS and BPA, such as automated on-line column-switching high performance liquid chromatography isotope dilution tandem mass spectrometry, 19 analytical paralysis gas chromatography mass spectrometry, 20 synchronous...

“…The mostly investigated electrocatalytic reactions include electrocatalytic oxidation of methanol/formic acid/CO as well as oxygen reduction reaction. To load these catalysts on diamond nanoparticles, numerous approaches have been developed, including electrodeposition [88,92], chemical reduction [93], and microwaveassisted polyol synthesis [91,99]. For example, electrodeposition of Pt nanoparticles on un-doped diamond nanoparticles (5-100 nm in diameter) were conducted in 1.1 mM chloroplatinic acid solution.…”

Macro-sized diamond films have been widely applied as the electrode for electrochemical and electroanalytical applications. Due to the non-uniform doping in diamond, boundary effects, and the varied ratios of graphite to diamond, only averaged electrochemical signals are detected over the full electrode. The studies of diamond electrochemistry at the nanoscale are thus highly required. In this chapter we overview recent progress and achievements about electrochemical properties and applications of diamond nanostructures and nanoparticles. After a brief introduction of the formation of these nanostructures and nanoparticles, electrochemical behavior of diamond nanostructures (e.g., diamond nanotexures, nanowires, networks, etc.) and nanoparticles (undoped, doped nanoparticles) in the presence/ absence of redox probes is summarized. Their electroanalytical (e.g., electrochemical, biochemical sensing, etc.) and electrochemical (e.g., energy storage using capacitors and batteries, electrocatalysis, etc.) applications are shown. Diamond nanoelectrode array is introduced and highlighted as a promising tool to investigate diamond electrochemistry at the nanoscale as well.

“…The key challenges involve preventing the stacking of graphene sheets and achieving complete dispersion of individual single-layer graphene in various solvents to support active phase. Unlike the simple agglomeration feature of 2D-structure graphene, some other 0D and/or 3D sp 2 carbon materials, such as onionlike carbon (OLC) and few-layer graphene (FLG), can be prepared easily and have been utilized and researched in catalysis as carbon supports [45][46][47][48][49][50].…”

Graphitized nanocarbon materials can be an ideal catalyst support for heterogeneous catalytic systems. Their unique physical and chemical properties, such as large surface area, high adsorption capacity, excellent thermal and mechanical stability, outstanding electronic properties, and tunable porosity, allow the anchoring and dispersion of the active metals. Therefore, currently they are used as the key support material in many catalytic processes. This review summarizes recent relevant applications in supported catalysts that use graphitized nanocarbon as supports for catalytic oxidation, hydrogenation, dehydrogenation, and C-C coupling reactions in liquid-phase and gas-solid phase-reaction systems. The latest developments in specific features derived from the morphology and characteristics of graphitized nanocarbon-supported metal catalysts are highlighted, as well as the differences in the catalytic behavior of graphitized nanocarbon-supported metal catalysts versus other related catalysts. The scientific challenges and opportunities in this field are also discussed. Keywords: nanocarbon materials; graphitized carbon supports; metal catalysts; hetergeneous catalysis INTRODUCTIONCarbon combines its atoms in diverse hybridization states (sp, sp 2 , sp 3 ) to form a variety of polymorphs. These are composed entirely of carbon but have different physical structures and different names, including diamond, graphite, fullerenes, and carbines, among others [1][2][3][4][5]. Because these various and versatile allotropes produce materials with a large range of properties, carbon materials can be used in a number of technological processes, including high-tech catalytic ones [6][7][8][9][10].In heterogeneous catalysis, carbon material plays wellestablished and important roles in a wide range of applications, both as catalyst in its own right and as a unique support material [11][12][13][14][15]. The chemical stability of carbon supports in some specifically aqueous phase biomass conversion surpasses that of metal oxide materials; in addition, carbon materials present other common and key advantages as support materials for catalysis [1,5]. From the point of physical structure, porous carbon can be prepared in different forms (granules, cloth, fibers, pallets, etc.). Due to its chemical properties, carbon structure is resistant to both acidic and basic media. The structure of carbon is stable at high temperature (even above 1023 K under inert atmosphere). The hydrophilic/ hydrophobic nature of carbon can be easily modified. Active metals on the support can be easily reduced. For the purposes of industrial economy and environment, the active phase can be easily recovered. Conventional carbon supports are lower-cost and more easily available than other conventional supports. Although several kinds of carbon materials have been studied, active carbon (AC) [12,[16][17][18][19] and, to a lesser extend, carbon black [20][21][22][23] have long been the most commonly used carbon supports. AC is an amorphous solid prepa...
