High yield and wide lateral size growth of α-MoC: exploring the boundaries of CVD growth of bare MXene analogues.

Synthesis of MoC bare MXenes, without surface terminations groups, via chemical vapor deposition (CVD) on metal foils is scientifically a very intriguing crystal growth process, and there are still challenges and limited fundamental understanding to overcome to obtain high yield and wide crystal size lateral growth. Achieving large area coverage via direct growth is scientifically vital to utilize the full potential of their unique properties in different applications. In this study, we sought to expand the boundaries of the current CVD growth approach for MoC MXenes and gain insights into the possibilities and limitations of large area growth, with a particular focus on controlling Mo concentration.

The Effect of Y Content on Structural and Sorption Properties of AB-Type Phase in the La-Y-Ni-Al-Mn System.

Metal hydrides are an interesting group of chemical compounds, able to store hydrogen in a reversible, compact and safe manner. Among them, AB-type intermetallic alloys based on La-Mg-Ni have attracted particular attention due to their high electrochemical hydrogen storage capacity (∼400 mAh/g) and extended cycle life. However, the presence of Mg makes their synthesis via conventional metallurgical routes challenging.

Preferential Orientation of Photochromic Gadolinium Oxyhydride Films.

We report preferential orientation control in photochromic gadolinium oxyhydride (GdHO) thin films deposited by a two-step process. Gadolinium hydride (GdH) films were grown by reactive magnetron sputtering, followed by oxidation in air. The preferential orientation, grain size, anion concentrations and photochromic response of the films were strongly dependent on the deposition pressure.

Mechanochemistry of Metal Hydrides: Recent Advances.

This paper is a collection of selected contributions of the that was held in Oslo in May 2018. In this paper, the recent developments in the use of mechanochemistry to synthesize and modify metal hydrides are reviewed. A special emphasis is made on new techniques beside the traditional way of ball milling.

Recent Advances in the Use of Black TiO for Production of Hydrogen and Other Solar Fuels.

Black TiO has emerged as one of the most promising photocatalysts recently discovered. The reason behind its catalytic activity is considered to be due to the presence of defects and Ti species at the surface of black TiO nanostructures, which are crucial for its diverse applications. Moreover, disordered/crystalline surface layers and bulk regions have been identified and appear to influence the intrinsic properties of the material.

Influence of nanoconfinement on morphology and dehydrogenation of the Li11BD4-Mg(11BD4)2 system.

The decomposition of a nanoconfined mixture of lithium-magnesium borohydride, Li(11)BD(4)-Mg((11)BD(4))(2), has been investigated and compared to the corresponding mixture in the bulk form. The systems were investigated by thermal analysis, small-angle neutron scattering, (11)B nuclear magnetic resonance and transmission electron microscopy. The dehydrogenation temperatures decreased by up to 60 °C in the nanoconfined system, with gas evolution following different steps, compared to the behaviour of the bulk material under the same conditions.

Small-angle scattering investigations of Mg-borohydride infiltrated in activated carbon.

One of the main challenges for introduction of a hydrogen-based economy is storage of hydrogen. Hydrogen storage in solid materials is considered among the most attractive methods. During recent years much emphasis has been placed on the synthesis of nanosized metals and alloys.
