Abstract
In this paper, a bimetallic Metal-Organic Framework (MOF) CoNiBTC was employed as a precursor for the fabrication of bimetallic nanoalloys CoNi@C evenly disseminated in carbon shells. These functional nanomaterials are characterized by powdered X-ray diffraction (PXRD), Fourier Transform Infra-Red spectroscopy (FTIR), surface area porosity analyzer, X-ray photoelectron spectroscopy (XPS), Field emission scanning electron microscopy (FESEM), Transmission electron microscopy (TEM), Hydrogen Temperature-Programmed Reduction (H2 TPR), CO2 Temperature-Programmed Desorption (CO2-TPD), and Inductively Coupled Plasma Mass Spectrometry (ICP-MS). This nanocatalyst was utilized in the synthesis of benzimidazole from o-phenylenediamine in the presence of CO2 and H2 in a good yield of 81%. The catalyst was also efficient in the manufacture of several substituted benzimidazoles with high yield. Due to the existence of a bimetallic nanoalloy of Co and Ni, this catalyst was also employed in the methanation of CO2 with high selectivity (99.7%).

Abstract
![]()
This research discusses
the CO2 valorization via hydrogenation
over the non-noble metal clusters of Ni and Cu supported on graphitic
carbon nitride (g-C3N4). The Ni and Cu catalysts
were characterized by conventional techniques including XRD, AFM,
ATR, Raman imaging, and TPR and were tested via the hydrogenation
of CO2 at 1 bar. The transition-metal-based catalyst designed
with atom-economy principles presents stable activity and good conversions
for the studied processes. At 1 bar, the rise in operating temperature
during CO2 hydrogenation increases the CO2 conversion
and the selectivity for CO and decreases the selectivity for methanol
on Cu/CN catalysts. For the Ni/CN catalyst, the selectivity to light
hydrocarbons, such as CH4, also increased with rising temperature.
At 623 K, the conversion attained ca. 20%, with CH4 being
the primary product of the reaction (CH4 yield >80%).
Above
700 K, the Ni/CN activity increases, reaching almost equilibrium values,
although the Ni loading in Ni/CN is lower by more than 90% compared
to the reference NiREF catalyst. The presented data offer a better
understanding of the effect of the transition metals’ small
metal cluster and their coordination and stabilization within g-C3N4, contributing to the rational hybrid catalyst
design with a less-toxic impact on the environment and health. Bare
g-C3N4 is shown as a good support candidate
for atom-economy-designed catalysts for hydrogenation application.
In addition, cytotoxicity to the keratinocyte human HaCaT cell line
revealed that low concentrations of catalysts particles (to 6.25 μg
mL–1) did not cause degenerative changes.

Thermal Conversion of Sugarcane Bagasse Coupled with Vapor Phase Hydrotreatment over Nickel-Based Catalysts: A Comprehensive Characterization of Upgraded Products. Catalysts 2022.

Abstract
In the present work, we compared the chemical profile of the organic compounds produced in non-catalytic pyrolysis of sugarcane bagasse at 500 °C with those obtained by the in-line catalytic upgrading of the vapor phase at 350 °C. The influence over the chemical profile was evaluated by testing two Ni-based catalysts employing an inert atmosphere (N2) and a reactive atmosphere (H2) under atmospheric pressure with yields of the liquid phase varying from 55 to 62%. Major changes in the chemical profile were evidenced in the process under the H2 atmosphere, wherein a higher degree of deoxygenation was identified due to the effect of synergistic action between the catalyst and H2. The organic fraction of the liquid phase, called bio-oil, showed an increase in the relative content of alcohols and phenolic compounds in the GC/MS fingerprint after the upgrading process, corroborating with the action of the catalytic process upon the compounds derived from sugar and carboxylic acids. Thus, the thermal conversion of sugarcane bagasse, in a process under an H2 atmosphere and the presence of Ni-based catalysts, promoted higher deoxygenation performance of the pyrolytic vapors, acting mainly through sugar dehydration reactions. Therefore, the adoption of this process can potentialize the use of this waste biomass to produce a bio-oil with higher content of phenolic species, which have a wide range of applications in the energy and industrial sectors.

Past, Present and Near Future: An Overview of Closed, Running and Planned Biomethanation Facilities in Europe. ENERGIES 2021.

Abstract
The power-to-methane technology is promising for long-term, high-capacity energy storage. Currently, there are two different industrial-scale methanation methods: the chemical one (based on the Sabatier reaction) and the biological one (using microorganisms for the conversion). The second method can be used not only to methanize the mixture of pure hydrogen and carbon dioxide but also to methanize the hydrogen and carbon dioxide content of low-quality gases, such as biogas or deponia gas, enriching them to natural gas quality; therefore, the applicability of biomethanation is very wide. In this paper, we present an overview of the existing and planned industrial-scale biomethanation facilities in Europe, as well as review the facilities closed in recent years after successful operation in the light of the scientific and socioeconomic context. To outline key directions for further developments, this paper interconnects biomethanation projects with the competitiveness of the energy sector in Europe for the first time in the literature. The results show that future projects should have an integrative view of electrolysis and biomethanation, as well as hydrogen storage and utilization with carbon capture and utilization (HSU&CCU) to increase sectoral competitiveness by enhanced decarbonization.
