The porous diatomite/Ni-S gradient structure achieves ideal impedance matching and multi-phase polarization, yielding outstanding microwave absorption: 93.5 dB minimum reflection loss at 15.86 GHz and an ultra-wide 6.66 GHz bandwidth (covering C/Ku bands). Moreover, it exhibits superior OER performance with a low overpotential (258 mV@10 mA cm⁻²) and Tafel slope of 82.62 mV dec⁻¹ in alkaline solution, outperforming the commercial RuO₂. High electrochemical surface area further supports enhanced kinetics. Crucially, bio-inspired design ensures thermodynamic stability (&lt;1 % mass loss, 20–400 °C) and durability for high performance of microwave adsorption, also bionic architecture improves the active sites density of the electrode to enhance water splitting.

In this work, an optimized calcination strategy is proposed to selectively obtain polycrystalline α-quartz from amorphous silica pellets by varying process parameters such as target temperature, dwell time, and cooling rates. Quantitative analyses by X-ray powder diffraction and scanning electron microscopy reveal that the initial density of the precursors significantly influences both the thermodynamics and kinetics of the structural phase transformation.

With the integration of the adsorption kinetics, isotherms, and thermodynamic studies, along with the various spectroscopic characterizations before and after adsorption, the adsorption mechanisms of KGP-2 for MO were investigated in detail. Selective adsorption tests demonstrated the high selectivity of KGP-2 for MO, and after six cycles of adsorption-desorption, the MO removal rate remained above 80 %, highlighting the stability and reusability of KGP-2.
