Quantum flatland i.e., the family of two dimensional (2D) quantum materials has become increscent and has already encompassed elemental atomic sheets (Xenes), 2D transition metal dichalcogenides (TMDCs), 2D metal nitrides/carbides/carbonitrides (MXenes), 2D metal oxides, 2D metal phosphides, 2D metal halides, 2D mixed oxides, etc. and still new members are being explored. Owing to the occurrence of various structural phases of each 2D material and each exhibiting a unique electronic structure; bestows distinct physical and chemical properties. In the early years, world record electronic mobility and fractional quantum Hall effect of graphene attracted attention. Thanks to excellent electronic mobility, and extreme sensitivity of their electronic structures towards the adjacent environment, 2D materials have been employed as various ultrafast precision sensors such as gas/fire/light/strain sensors and in trace-level molecular detectors and disease diagnosis. 2D materials, their doped versions, and their hetero layers and hybrids have been successfully employed in electronic/photonic/optoelectronic/spintronic and straintronic chips. In recent times, quantum behavior such as the existence of a superconducting phase in moiré hetero layers, the feasibility of hyperbolic photonic metamaterials, mechanical metamaterials with negative Poisson ratio, and potential usage in second/third harmonic generation and electromagnetic shields, etc. have raised the expectations further. High surface area, excellent young’s moduli, and anchoring/coupling capability bolster hopes for their usage as nanofillers in polymers, glass, and soft metals. Even though lab-scale demonstrations have been showcased, large-scale applications such as solar cells, LEDs, flat panel displays, hybrid energy storage, catalysis (including water splitting and CO2 reduction), etc. will catch up. While new members of the flatland family will be invented, new methods of large-scale synthesis of defect-free crystals will be explored and novel applications will emerge, it is expected. Achieving a high level of in-plane doping in 2D materials without adding defects is a challenge to work on. Development of understanding of inter-layer coupling and its effects on electron injection/excited state electron transfer at the 2D-2D interfaces will lead to future generation heterolayer devices and sensors.

“…A positive role of acid sites on the surface of the support material in achieving a high pyrrolidone yield was observed, which is associated with the acceleration of EL amination and cyclization steps [9][10][11][12][13][14]21,25]. Nickel phosphides are attracting increased attention as bifunctional catalysts due to the presence of both metal and acid sites [26][27][28]. It is generally accepted that nickel phosphides contain weak Brønsted and Lewis acid sites, which are associated with P-OH groups and coordinatively unsaturated Ni δ+ sites, respectively.…”

Levulinic acid and its esters (e.g., ethyl levulinate, EL) are platform chemicals derived from biomass feedstocks that can be converted to a variety of valuable compounds. Reductive amination of levulinates with primary amines and H2 over heterogeneous catalysts is an attractive method for the synthesis of N-alkyl-5-methyl-2-pyrrolidones, which are an environmentally friendly alternative to the common solvent N-methyl-2-pyrrolidone (NMP). In the present work, the catalytic properties of the different nickel phosphide catalysts supported on SiO2 and Al2O3 were studied in a reductive amination of EL with n-hexylamine to N-hexyl-5-methyl-2-pyrrolidone (HMP) in a flow reactor. The influence of the phosphorus precursor, reduction temperature, reactant ratio, and addition of acidic diluters on the catalyst performance was investigated. The Ni2P/SiO2 catalyst prepared using (NH4)2HPO4 and reduced at 600 °C provides the highest HMP yield, which reaches 98%. Although the presence of acid sites and a sufficient hydrogenating ability are important factors determining the pyrrolidone yield, the selectivity also depends on the specific features of EL adsorption on active catalytic sites.

“…This can cause unwanted S-contamination in the end product and thus harmful environmental problems. Taking into account the above, research efforts in the last decade have progressively turned to the metallic form of the transition metals (e.g., Ni, Co, Fe), ,− metal carbide, − metal phosphide, − and metal nitride , catalysts.…”

In the present work the valorization of natural mordenite as a catalyst support was investigated. Natural mordenite of Greek origin was activated by acid treatment with an aqueous solution of HCl. This treatment led to a material with a high specific surface area (156 m2 g–1). Ni catalysts (10 wt % Ni) supported on activated mordenite were synthesized by incipient wetness impregnation (IWI), wet impregnation (WI), infiltration (INF), and deposition–precipitation (DP). They were evaluated for the biodiesel upgrading into renewable diesel via hydrotreatment. DP was proven to be the most effective preparation method. In fact, an almost total conversion of biodiesel and production of the highest amount of green diesel (14 wt % of the liquid product) was achieved over the catalyst prepared by DP. Its high efficiency was attributed to its enhanced specific surface area, better nickel dispersion (smaller size of crystallites), and the smaller amount of carbon deposits on its surface compared to the other catalysts of this series. When the DP method was adopted, nickel catalysts supported on activated mordenite were synthesized varying active phase loading in the range 10–30 wt %. The catalyst with the maximum nickel loading exhibited high specific surface area and the highest Ni surface area as well as a balanced population of weak and strong acid sites. These characteristics resulted in the highest efficiency for green diesel production (25 wt % of the liquid product) among the catalysts studied.
