Catalytic processes are mostly incorporated in a majority of industrial processes, so catalysts synthesis characterization and performance are crucial steps for the amelioration of the rate control, selectivity, and specificity of the chemical reactions. Carbon-based supports are being introduced nowadays as appropriate materials support of catalysts compared to the most popular Al2O3 and/or SiO2, for its interesting properties, such as control of pore size and pore size distribution, nanostructural control, and surface chemistry tailoring. Nonetheless, the intrinsic properties of carbon-based materials play themselves a wide number of catalytic processes beyond supporting materials. Thus, carbon-based materials as catalysts can exhibit a plethora of applications in fields like photocatalysis, electrocatalysis, and photoelectrocatalysis, among many others, by simply tailoring their textural, structural and surface chemistry properties. Synthetic and electrosynthetic processes, energy driven reactions, sensing and environment remediation take advantages of the proper design and performance of carbon based catalysts. The main aim of this Special Issue is to present the most relevant and recent insights in the field of carbon based catalytic materials aiming mainly at the fundamental and applicable aspects by seeking for the influence of physical–chemical properties of carbon materials on rate and performance in chemical kinetics.
We look forward to your submission.

Title: The role of structural and surface properties of phosphorylated carbon materials on the catalytic performance in dehydration reactions
Author: Sebastiano Campisi
Abstract: Phosphorylated carbons have been reported to be effective catalysts in dehydration reactions for biomass valorisation. The amount and the nature of P and O groups are a key parameter affecting the catalytic performances of functionalized materials. Herein, we investigate the role of structural and surface properties of carbon based materials in determining the number and the distribution of P-functionalities. Various carbon-based materials, namely activated carbon (AC), ordered mesoporous carbon (OMC), graphite (Graph) and carbon nanofibers (CNFs) with different graphitization degree, have been functionalized through treatment with a H3PO4-HNO3 mixture at 150°C. Surface and structural properties of bare and functionalized materials have been investigated by X-ray photoelectron spectroscopy (XPS), Raman Spectroscopy and Temperature-Programmed Desorption (TPD) experiments. The catalytic behaviour of phosphorylated carbon materials has been evaluated in the selective dehydration of fructose to HMF in order to elucidate structure-activity relationships.
Title: Electrostatic Adsorption of Platinum on Carbon Nanotubes and Nanofibers
Author: John Regalbuto, Ritubarna Banerjee
Abstract: Strong Electrostatic Adsorption (SEA) has been demonstrated as a simple, scientific method to prepare well dispersed Pt nanoparticles over typical forms of carbon: activated, black, and graphitic carbons. Many varieties of specialty carbons have been invented in the last few decades including multi-walled nanotubes, nanofibers, graphene nanoplatelets, etc. In this work we explore whether SEA can be applied to these specialty carbons for the synthesis of Pt nanoparticles.Over a number of oxidized and unoxidized multiwalled nanotubes and nanofibers the point of zero charge (PZC) was measured and the uptake of anionic Pt complexes (Pt hexachloride, [PtCl6]2-, and cationic Pt complexes (platinum tetraammine, [Pt(NH3)4]2+) as functions of final pH were surveyed. Pt nanoparticles on the various supports were synthesized at the optimal pH and were characterized by XRD and STEM. The specialty carbons displayed volcano-shaped uptake curves typical of electrostatic adsorption for both Pt anions at low pH and Pt cations at high pH. However, the regimes of uptake often did not correspond to the measured PZC. It was seen that the PZC of many of the carbons could be changed with washing, and so was likely affected by residual impurities of the manufacturing process. This renders the measured PZC of these specialty carbons unreliable for predicting anion and cation uptake. On the other hand, the anion and cation uptake curves provide an “effective” PZC and do indicate the optimal pH for the effective synthesis of ultrasmall nanoparticles.
