Interests: heterogenous catalysis (synthesis, chemico-physical characterization, structure-activity relationship); biofuels; additives for biofuels; green chemistry; reaction kinetics and mechanism; CO2 conversion
Solid catalytic materials play a key role in the development of industrial chemistry, showing important advantages over liquid materials thanks to their easier separation from the reaction liquid medium, their reusability and stability, and their environmentally-friendly character. This Special Issue is focused on the actual and potential application of heterogeneous catalysts for energetic purposes, as biofuels synthesis and H2 production through biomass, waste, biogas or CO2 conversion with specific interest towards innovative procedures of synthesis or catalytic formulations and chemicophysical characterization tecniques. For example, in situ and operando characterization techniques represent a suitable tool to identify and quantify the nature and functionality of surface adsorption active sites and, therefore, for correlating the catalytic behavior with the surface properties of the investigated systems. Based on this, by considering the importance of heterogeneous catalytic processes in the field of green chemistry, efficiency, sustainability, and environmental safety, it is my pleasure to invite you to submit original research papers or short reviews and communication for the Special Issue “Heterogeneous Catalytic Materials: Synthesis, Characterization and Applications for Energetic Purposes”.

Title: Zr-based oxides for biofuels synthesis and H2 production
Author: Dr. Nicola Scotti
Affiliation: ISTM-CNR, Italy
Abstract: Zr-based oxides are received increasing attention from the scientific community as heterogeneous catalysts and supports for metal nanoparticles, owing to their tunable phase composition, redox, and acid/base properties. High catalytic activity and selectivity have been reported for different classes of reactions such as hydrogenation with H2, transfer hydrogenation, dehydrogenation, dehydrogenative coupling, H2 production, and dehydration. In this view, the application of these kind of catalysts for biomass transformation for energy purpose is really promising, but requires a deep understating of their structure and activity in order to tune activity and selectivity and adapt the material for the desired application. In this review all these aspects will be discussed in a critical way.

Abstract: The yield and composition of the biocrude obtained by hydrothermal liquefaction (HTL) of Nannocloropsis gaditana using heterogeneous catalysts based on metal oxides (CaO, CeO2, La2O3, MnO2 and Al2O3) were evaluated. The reactions were performed in a batch autoclave reactor at 320oC during 10 min with a 1:10 (wt/wt) microalga:water ratio. These catalysts increased the yield of the liquefaction phase (from 94.3±0.9 wt% for La2O3 to 99.5±0.7 wt% for MnO2) as compared with the thermal reaction (92.6±0.7 wt%). Therefore, the conversion of the microalga improved, decreasing the solid fraction yields. Consequently, the biocrude yields also raised in the metal oxides catalyzed HTL, showing values remarkable higher for the CaO (50±1 wt%) in comparison to the HTL without catalyst (42.3±1 wt%). The nitrogen and oxygen content of the biocrude obtained from thermal HTL were 6.12±0.02 and 10.8±0.2 wt%, respectively. In this sense, the use of the metal oxides decreased the nitrogen content of the biocrude (4.17±0.03 - 5.3±0.01 wt%). However, these catalysts slightly increased its oxygen content (11±0.30 - 21.64±0.04 wt%).

Title: H2 photo-production: From materials to photo-reactors
Authors: Mario J. Muñoz-Batista*, et al.
Affiliation: University of Granada, Granada, Spain
Abstract: Photo-reforming of oxygenates is considered one of the most interesting process to produce H2 as a new clean energy vector and is mainly based on the potential utilization of sunlight or efficient illumination conditions and mind operation condition conditions. The process is strongly defined by the used semiconductor which must be optimized to provide the positive change photo-handling. This contribution focus on the utilization of two main groups of materials which have provided outstanding results in this reaction, named TiO2-based and g-C3N4-based materials. Traditional and advanced characterization approaches to understanding the process occurring under properly illumination condition are also reviewed. Special attention has been paid on in situ and operando studies. The work also summarize the main properties of photo-reactor setups in both liquid and gas media and describes a light-matter interaction modelling approach, which allows developing intrinsic kinetic modelling studies as well as the calculation of true quantum efficiency as main observable recommended by the IUPAC to analyze photocatalytic reactions.
