The recent chemical exfoliation of layered MAX phase compounds to novel two-dimensional transition metal carbides and nitrides, the so-called MXenes, has brought a new opportunity to materials science and technology. This review highlights the computational attempts that have been made to understand the physics and chemistry of this very promising family of advanced two-dimensional materials, and to exploit their novel and exceptional properties for electronic and energy harvesting applications.

A type of Pd/α-Fe 2 O 3 catalyst was synthesized by a convenient UV light-induced reduction in the presence of Fe 3+ ions. The synthesized Pd/α-Fe 2 O 3 particles were characterized by X-ray diffraction (XRD), low-resolution transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HR-TEM), X-ray photoelectron spectrum (XPS), atomic force microscope (AFM), scan electron microscopy with energy dispersion spectra (SEM-EDS), FT-IR and BET. Related characterizations confirm that UV light-induced reduction is a feasible, simply and environment-friendly method for the preparation of supported catalysts containing active metal. Furthermore, hydrogenation of o -chloronitrobenzene ( o -CNB) to o -chloroaniline ( o -CAN) by the selected Pd(0.5%)/α-Fe 2 O 3 was investigated systematically. The α-Fe 2 O 3 -supported Pd catalyst was found to exhibit good catalytic activity and selectivity for the o -CNB reduction under mild conditions. The hydrogenation of o -CNB over the resulting Pd-based catalyst gave a 100% o -CNB conversion and 91.4% selectivity of o -CAN under the reaction conditions of 50 °C, 2 h, 1 MPa hydrogen pressure, n o -CNB /n Pd  = 6000:1. Moreover, the resulting Pd-based catalyst remained higher hydrogenation reactivity after three runs even if a sharply decrease in activity was observed at the fourth run. The obtained results reveal the as-prepared Pd/α-Fe 2 O 3 is an efficient catalyst for the hydrogenation of o -CNB even at a high level of substrate concentration.

The development of highly-efficient heterogeneous supported catalysts for catalytic hydrolysis of ammonia borane to yield hydrogen is of significant importance considering the versatile usages of hydrogen. Herein, we reported the in situ synthesis of AgCo bimetallic nanoparticles supported on g-C3N4 and concomitant hydrolysis of ammonia borane for hydrogen evolution at room temperature. The as-synthesized Ag0.1Co0.9/g-C3N4 catalysts displayed the highest turnover frequency (TOF) value of 249.02 mol H2·(molAg·min)−1 for hydrogen evolution from the hydrolysis of ammonia borane, which was higher than many other reported values. Furthermore, the Ag0.1Co0.9/g-C3N4 catalyst could be recycled during five consecutive runs. The study proves that Ag0.1Co0.9/g-C3N4 is a potential catalytic material toward the hydrolysis of ammonia borane for hydrogen production.
