Article Abstract
The growing demand for improved electrochemical performance in energy storage systems has stimulated research into advanced two-dimensional (2D) materials for electrodes. In this work, we obtain a layered MXene compound by exfoliating a titanium aluminum carbide precursor using tetramethylammonium hydroxide (TMAOH) ions in a full room temperature process followed by manual shaking. The hexagonal crystal structure and composition of the layered materials are characterized using different techniques. X-Ray diffraction shows the formation of 2D nano-sheets before and after the TMAOH treatment via its characteristic (002) diffraction peak, bringing to light an increase in the interlayer spacing after treatment. Scanning electron microscopy images confirm the layered morphology, whose composition is determined by energy dispersive x-ray analysis for the bulk material and by x-ray photoelectron spectroscopy for the surface of the obtained compounds. This study demonstrates a promising route to enhance delamination of this MXene 2D material in a low-cost room-temperature approach.

A visible-light-induced cascade cyclization of isocyanobiaryls with hydrosilanes has been developed for the synthesis of 6-silylated phenanthridines. Readily available hydrosilanes were employed as silyl radical precursors under room-temperature conditions. The merits of the transformation include operational simplicity, mild conditions, high atom economy, and good functional group compatibility.

Noble metal nanoparticles (NPs), particularly platinum (Pt), are widely used in heterogeneous catalysis due to their exceptional activity. However, controlling their size and preventing sintering during synthesis remains a major challenge, especially when aiming for high dispersion and stability on supports such as graphene. Atomic layer deposition (ALD) has emerged as a promising method to address these issues, yet conventional processes often lead to broad particle size distributions (PSDs).

We report the synthesis of three nickel complexes based on Ni(NHC)[P(OR)](Ar)Cl and their application in C()-N cross-coupling reactions. Reactions involving secondary amines proceeded at room temperature, while anilines and primary alkyl amines coupled under mild heating. The reported complexes are air-stable as solids, operate at low catalytic loading, and do not require an exogenous ligand.

Through high-pressure diamond anvil cell experiments, we report the synthesis of two novel potassium superhydrides (KH-I and KH-II) and investigate their structural and vibrational properties via synchrotron X-ray powder diffraction and Raman spectroscopy, complemented by density functional theory (DFT) calculations. Above 17 GPa at room temperature, KH-II and H react to form KH-I; this reaction can be accelerated with temperature. KH-I possesses a face-centered-cubic () potassium sublattice with a slight rhombohedral distortion (space group 3̅).

The construction of strong metal-support interactions (SMSI) is an effective strategy to enhance and control heterogeneous catalysts. However, conventional methods require pre-synthesized metal-loaded catalysts, followed by SMSI formation via high-temperature treatment under oxidative/reductive atmospheres, adsorbate-mediated treatment, and photo-treatment, adding complexity to catalyst synthesis and hindering continuous interfacial tuning. In this work, a "photobreeding" method is employed to treat ZnCdS, leveraging the UV-induced photochromic reaction of ZnS to generate metallic Zn at room temperature, while CdS remains inert.
