“…The N 1s region shows a Ga–N peak at 397.5 eV , with an atomic ratio of 66% at 50 ppm that increased to 87.2% at the highest NH 4 OH concentration, as reported in Table . When the experiment was performed in the absence of CO 2 bubbling, this ratio was consistent at 83.1%.…”

“…It should be noted that Ga Auger peaks were detected at 394 eV in all samples. 63,64 The O 1s region in Figure S5 shows Ga−OH peaks in the 531.5−532.3 eV 64 range relevant to an oxygen-deficient GaOOH phase, where the atomic ratio increases at higher NH 4 OH compared to the lattice oxygen Ga−O peak of Ga 2 O 3 at 530.5 eV. 61 This result suggests that the incorporation of N decreases the level of oxidation of GaOOH to Ga 2 O 3 .…”

Carbon dioxide emission is a major cause of environmental concern, such as global warming and ocean acidification. Therefore, there is an ongoing search for feasible carbon dioxide reduction processes that utilize renewable energy to convert CO 2 into a valuable product. Here, we report a versatile sonochemical process for the permanent removal and conversion of carbon dioxide into acetamide and liquid oxygenates using a Ga liquid metal-based reductant. Liquid metals are ideal for CO 2 reduction due to their notable catalytic properties at low temperatures, nontoxicity, and relatively low cost. The process involves ultrasonication of water-suspended liquid Ga droplets, leading to the formation of GaOOH, which is further sonicated in the presence of an aqueous solution of NH 4 OH with a CO 2 feed at a low temperature of 70 °C. Liquid C 2 and C 3 oxygenate products were formed including industry-relevant acetamide, ethanol, and acetone platform chemicals. In addition, solid-phase gallium nitride and oxynitride nanomaterials were formed, which could be utilized in various catalytic and electronic applications.

Due to population growth and global technological development, energy consumption has increased exponentially. The global energy crisis opens up many hotly debated topics regarding energy generation and consumption. Not only is energy production in short supply due to limited energy resources but efficient and sustainable storage has become a very important goal. Currently, there are energy storage devices such as batteries, capacitors, and super-capacitors. Supercapacitors or electrochemical capacitors can be very advantageous replacements for batteries and capacitors because they can achieve higher power density and energy density characteristics. The evolution and progress of society demand the use of innovative and composite nanostructured metal oxide materials, which fulfill the requirements of high-performance technologies. This review mainly addresses the synthesis techniques and properties of 2D and 3D metal oxide nanostructured materials, especially based on Ti, Fe, Ga, and Sn ions, electrochemical methods used for the characterization and application of 2D, and 3D nanostructured metal oxide structures in electrochemical storage systems of energy.
