Specifically, the CoNi11 alloy (Co/Ni = 1) demonstrated exceptional HER performance, achieving a low overpotential of 162.2 mV (vs. RHE) at 10 mA cm−2, a Tafel slope of 69.2 mV dec−1, and a high electrochemically active surface area (ECSA) of 200.3 mF cm−2.

Herein, we describe the use of a simple ultrasonic method to prepare a gelatin-based FeS2-gC3N4 (GL/FS-CN) composite for the photocatalytic degradation of the reactive red 24 (RR 24) dye. The GL/FS-CN composite was characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), ultraviolet-visible (UV-vis) spectroscopy, scanning electron microscopy (SEM), N2 adsorption at −196 °C, zeta potential analysis, and X-ray photoelectron spectroscopy. The photocatalytic degradation of 91.78% achieved with GL/FS-CN demonstrates a notable improvement over FS and CN, highlighting the potential of this method for enhancing photocatalytic efficiency. The presence of gelatin with FS and CN helped enhance photocatalytic efficiency and reduce the recombination rate. The main active species involved in degradation were superoxide radicals (O2˙−), as the degradation efficiency decreased to 78.22%, 80.13%, and 55% when EDTA, IPA, and BQ were added as sacrificial agents, respectively. The photocatalytic degradation of RR 24 dye followed pseudo-first-order kinetics, with a rate constant of 0.02944 min−1. XRD analysis revealed a crystallite size of 8.92 nm. Thermodynamic parameters (ΔS°, ΔH°, and ΔG°) were measured at various temperatures, showing the endothermic and spontaneous nature of the reaction.

In this study, we investigate the nanoscale photocurrent behavior of perovskite films deposited on photonic-structured TiO2, contrasting their performance with conventional mesoporous TiO2 (mp TiO2). By leveraging nanoscale photocurrent mapping, we reveal that photonic-structured TiO2 fosters stable and sustained photocurrent generation, attributed to enhanced charge retention and suppressed recombination. In contrast, perovskite films on mp TiO2 exhibit photocurrent degradation over time due to charge trapping and instability. These findings underscore the transformative role of photonic-structured TiO2 in modulating charge carrier dynamics, advancing our understanding of perovskite material behavior.

To address this issue, this study successfully prepared two novel types of kaolin/corn straw biochars through high-temperature pyrolysis and nanoparticle modification, and investigated their adsorption performance for OTC and CTC in water. The characterization results showed that the two modified biochars had a high specific surface area and developed pore structures, which were conducive to improving adsorption efficiency. The batch adsorption experiments showed that the nano-CuFe2O4 modified biochar (KLBCCF) was superior to the nano-CuO modified biochar (KLBCC) in terms of adsorption capacity, interference resistance, and regeneration performance. The pseudo-second-order kinetic model and the Langmuir model can better fit the OTC and CTC adsorption processes by KLBCCF. At 318.15 K, the adsorption capacities of KLBCCF for OTC and CTC were determined to be 170.21 and 316.26 mg g−1, respectively. The thermodynamic analysis showed that the adsorption process was spontaneous, heat-absorbing, and entropy-increasing. The adsorption mechanisms of OTC and CTC on KLBCCF included pore filling, hydrogen bonding, surface complexation, electrostatic interactions, and π–π interactions.
