“…In another work, using the incipient humidity method, Ni-Mo 2 C supported over HAp was prepared for the production of hydrogen from cellulosic biomass. 157 The HAp was obtained from the thermal extraction of bovine bones at a range of 700-900 °C. Mo 2 C particles doped with Ni were produced at 900 °C in a hydrogen-reducing atmosphere.…”

The application of (bio)wastes as alternatives to expensive existing catalysts is an approach that can be used to reduce environmental pollution problems. Animal bone wastes have attracted much attention as environmentally friendly heterogeneous catalysts for chemical transformations such as transesterification, oxidation, and biofuel production, owing to the substantial availability of valuable hydroxyapatite (HAp) in their structure. Most catalysts based on bone can be prepared easily by calcination. High-temperature calcination yields highly active catalysts. Heterogeneous catalysts prepared from these renewable sources could also simply be reused and recovered without any important loss of catalytic performance. This paper reviews past efforts and recent progress on the development of different eco-friendly catalysts derived from bone waste and some of their catalyzed chemical transformations. However, future challenges focus on crediting the conversion of unusable wastes to valuable sources to meet global requirements

“…Apart from the properties commonly shared by TMCs, Mo 2 C also has the electronic structure and catalytic functions similar to those of the precious metal Pt, which is opening up new prospects in a wide range of important applications in 2D materials, composite materials, energy storage, superconductivity and catalysis [10][11][12]. As a new functional material, Mo 2 C has the potential to replace the industrial hydrogenation catalyst with a very efficient catalytic effect, which has high importance to scientific research and technological developments [13][14][15][16][17].…”

Insight into Point Defects and Complex Defects in β-Mo2C and Carbide Evolution from First Principles

et al. 2022

In this paper, first principles method was adopted to investigate the point defects, Vanadium-related defects and defect combinations (vacancy (V), substitutional (S) and/or interstitial (I)) in molybdenum β-Mo2C and explore the use of first principles calculation data in analysing the link between different carbides and the effects of doping elements. Supercell models with different defect types were established and optimized, and the formation energy data of defects was developed. The structure evolution during the optimization process is analysed in detail to establish the main characteristics of changes and the relevant electronic properties. The data for different types of intrinsic defects and combined defects complexes was developed and key results is analysed. The results show that carbon vacancy (VC) is stable but does not inevitably exist in pure β-Mo2C. Interstitial site II is a very unstable position for any type of atoms (Mo, V and C), and analysis of the structure evolution shows that the atom always moves to the interface area near the interstitial site I between two layers. In particular, a C atom can expand the lattice structure when it exists between the layer interfaces. One type of the defects studied, the substitution of Mo with V (designated as ‘SV-Mo’), is the most stable defect among all single point defects. The data for defect complexes shows that the combination of multiple SV-Mo defects in the super cell being more stable than the combination of other defects (e.g., ‘VMo+IC’, ‘SV-Mo+VC’). The data with increasing SV-Mo in (Mo, V)2C system is developed, and typical data (e.g., formation energy) for Mo-rich carbides and V carbides are correlated and the potential of the data in analysing transition of different carbides is highlighted. The relevance of using first principles calculation data in the studying of V-doping and the complex carbides (V- and Mo-rich carbides) evolution in different materials systems and future focus of continuous work is also discussed.
