Carbon research and technology has seen extraordinary advances in last few decades, leading to the synthesis of a wide variety of carbon materials that present different properties, depending on their structure, texture, chemistry, shape, size, etc., which has allowed broadening their application possibilities in different fields of electronics, biomedical, energy, chemical and environmental technologies. Heterogeneous catalysis has a relevant role in many chemical, electrochemical, photochemical and biological processes. The possibility of tailoring the physical surface characteristics and pore size distribution, and of modifying the surface chemistry during their synthesis, makes carbon materials suitable, not only as catalyst supports, but as catalysts themselves, satisfying most of the requirements for many different catalytical applications, given that these materials show also chemical and thermal stability and mechanical resistance. Exploiting the chemical surface properties of carbon materials by surface functionalization, allowing the introduction of different heteroatoms (oxygen, nitrogen, phosphorus, sulfur, boron) on the carbon surface that improves anchoring, immobilizing and/or dispersing the catalytic active phase to the carbon support or adds specific functionalities, is also a powerful tool when designing carbon-supported catalysts and/or carbon catalysts, strongly influencing the catalytic behavior in terms of conversion, selectivity, stability, etc.
Controlling the structural order, size and conformation of carbon materials may lead to significant changes in catalytic behavior. Thus, nanoarchitectures like those of graphene and carbon nanotubes may present different catalytical properties than those of activated carbons, carbon aerogels or xerogels. Carbon material morphology is also of great importance for catalytical applications, in order to avoid reactor pressure drop and transport limitations and, in this sense, different physical forms of carbons can be produced, such as granules, pellets, monoliths, fibers, cloths, spheres, etc. On the other hand, carbon materials can be synthetized from many different precursors such as coals, hydrocarbons, oil and coal derivatives, biomass, agro-alimentary and agroforestry industrial waste, etc. The nature of carbon precursors and the synthesis route and operation conditions play an important role in the final carbon material properties and characteristics that control and govern the catalytical applications.
This Special Issue deals with the study of advanced carbon materials for catalytical applications, covering materials preparation, functionalization, characterization, engineering and applications in the field of heterogeneous catalysis, such as catalysis, electrocatalysis, photocatalysis, biocatalysis, environmental remediation, etc.

Biomass tar removal and syngas production over rice husk char-supported nickel catalysts under microwave condition
Abstract: In the present work, in-situ biomass pyrolysis tar cracking and reforming together with the high quality syngas production over rice husk (RHC)-supported nickel catalysts(Ni/RHC) coupled with microwave heating was investigated. The surface area and pore properties of the RHC and Ni/RHC catalysts were determined by applying a Micromeritics instrument ASAP 2020. The Ni loading amount and contents of the other metal element contained in the RHC were determined by using an ICP-OES. The contents of the acid functional groups present in RHC before and after reactions were analyzed by using Boehm titration method. The Ni/RHC catalysts before and after reactions were also characterized. The Ni/RHC catalysts exhibited high catalytic performance on tar removal and were much favorable to the production of CO and H2. The conversion rate could reach up to 97.34% together with the CO and H2 yields being 274.03 ml/g and 248.87 ml/g, respectively, at 700 oC under microwave condition when the nickel loading amount was 10.42 wt.% of the supporter. The tar conversion rates and the syngas yields were significantly increased with the cracking temperatures increasing from 500oC to 700oC and the nickel loading amount increasing from 0 to 10.42 wt.%. The Ni/RHC catalysts became more effective on the tar removal and syngas production under microwave condition than under conventional condition.
