The incorporation of aluminium-based compounds boosted surface reactivity, mechanical stability, and electrolyte interaction of the composite. The aerogels exhibited a high surface area (261 m² g⁻¹) and a permeable microstructure, ideal for supercapacitor (SC) electrodes. Among various compositions, the sample with a 1:1 wt ratio of graphene oxide to Al(NO₃)₃·9H₂O (SAlGH-2) delivered the best electrochemical performance, achieving in a symmetric two-electrode SC a specific capacitance of 131.5 F g⁻¹, an energy density of 36.5 Wh kg⁻¹, and a power density of 328.8 W kg⁻¹ at a scan rate of 5 mV s⁻¹. In parallel, a COMSOL Multiphysics model incorporating pseudocapacitive and electrochemical double-layer capacitance (EDLC) processes provided insights into ion diffusion and interfacial charge storage behaviour during cyclic voltammetry. This performance stems from the synergistic effect of rGO's electric double-layer capacitance, the conductivity and pseudocapacitance of AlO(OH)/Al₂O₃, and the aerogel's hierarchical porous structure. The SC demonstrated excellent durability, with 95.5 % coulombic efficiency and 76 % specific capacitance retention after 10,000 cycles.

Here, photocatalysts were synthesized from copper smelting flotation slags from Uzbekistan for hydrogen production. The crystallinity of the two main phases of the slag, CuFe₂O₄ and Fe₃O₄, was increased by calcinating the slag (Cal900Air5h). Subsequently, the Cal900Air5h was composited with TiO₂ by in-situ hydrothermal reaction (TiO₂-5 %Cal900Air5h_HT). The TiO₂-5 %Cal900Air5h_HT catalyzed the production of a significant amount of H₂, 2.6 times more than pure TiO₂.

This suggested other amorphous phases including Si, Ca, and Al in Cal900Air5h, which are insulators by themselves, might contribute in an indirect way to the photocatalytic reactions. A possible mechanism of the photocatalytic H₂ evolution is as follows: The band structure determined using various techniques indicated that a Type II heterojunction formed mainly between TiO₂ and CuFe₂O₄ and less between TiO₂ and CuO in the calcined material. Therefore, when the composite was exposed to light, electrons were excited in both phases of TiO₂ and CuFe₂O₄ (slightly CuO) in the calcined slag, and then the excited electrons were transferred from CuFe₂O₄ and CuO to TiO₂ through the heterojunction. The electrons were accumulated on the TiO₂ side, and the photocatalytic reduction of H₂O molecules into H₂ on the surfaces of Pt (0) nanoparticles serving as a cocatalyst.

A specialised fibreboard manufacturing setup, incorporating a drum mixer, tube blender, and hot press, was developed to fabricate the composite boards. Results indicate that increasing the hot-pressing time enhances both flexural and internal bond strength.
