Article Abstract
This article reports a novel fabrication method for In(OH)3 from indium oxalate by hydrothermal process. Hydrothermal decomposition of indium oxalate at 180 degrees C for 10 h results in In(OH)3. The influence of hydrothermal experimental conditions such as temperature, time on the formation of indium hydroxide was investigated. The self-assembly process was strongly influenced the experimental conditions. The thermal decomposition of In(OH)3 at 400 degrees C results In2O3. The synthesized In(OH)3 and In2O3 were characterized using X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), high resolution transmission electron microscopy (HR-TEM), thermal analysis (TGA and DTA), diffuse reflectance spectra (DRS), and nitrogen adsorption analysis. The XRD patterns indicated the formation of well crystallized cubic phase In(OH)3 and In2O3. The FE-SEM results indicated formation of In(OH)3 and porous In2O3 nano/micro-cubes. The photocatalytic activity of the synthesized In(OH)3 was studied under UV light irradiation and results showed that the In(OH)3 photocatalyst was efficient for dye degradation. We proposed a plausible mechanism for the formation of In(OH)3, and In2O3 self-assembly.

Recently, because of the urgent need for safety and health protection, there has been a growing focus on exploring effective and feasible gas sensors based on metal oxide semiconductors (MOSs) for detecting trace levels of hydrogen sulfide (HS). In this context, a cobalt (Co) doping strategy was proposed to improve the HS-sensitive properties of InO nanomaterials, enabling them to monitor 1 ppm of HS at a relatively lower temperature. The Co-doped InO hierarchical porous nanocubes (Co-InO HPNCs) were prepared through a hydrothermal route using In(OH) as a precursor.

The efficient and economic conversion of CO and renewable H into methanol has received intensive attention due to growing concern for anthropogenic CO emissions, particularly from fossil fuel combustion. Herein, we have developed a novel method for preparing Ni/InO nanocatalysts by using porous MIL-68(In) and nickel(II) acetylacetonate (Ni(acac)) as the dual precursors of InO and Ni components, respectively. Combined with in-depth characterization analysis, it was revealed that the utilization of MIL-68(In) as precursors favored the good distribution of Ni nanoparticles (∼6.

Indium hydroxide (In(OH)) and indium oxide (InO) have proven to be efficient catalysts for photocatalytic water-splitting reactions to produce hydrogen (H) and for organic pollutant degradation applications. However, the limited optical absorption features of indium-based nanostructures have restricted their practical applications. In this study, we have successfully designed indium hydroxide- and indium oxide-loaded metal sulfide (cadmium sulfide, CdS) heterostructures as excellent photocatalytic systems for photocatalytic hydrogen evolution and tetracycline hydrochloride pollutant degradation reactions.

Zr-doped InO thin films are prepared on FTO substrates by a two-step method: firstly, Zr-doped In(OH) thin films are hydrothermally deposited, and then converted to Zr-doped InO films by heat treatment. It is found that during the phase transition from Zr-doped In(OH) to Zr-doped InO, the cuboid-like crystal grains will fragment, resulting in a large number of new surfaces and cracks. Zr doping can introduce shallow impurity levels in the band gap of InO, which will enhance the absorption of incident light.
