This study systematically investigates the effects of Ce doping and thermal reduction on the bandgap of ZrO₂ by experiments and density functional theory (DFT) calculations. The results demonstrate that both Ce doping and thermal reduction facilitate the formation of oxygen vacancies (O_V) through distinct mechanisms, ultimately leading to the bandgap reduction of ZrO₂. As X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectroscopy (XPS), Raman, and electron paramagnetic resonance revealed, Ce doping can induce the cell distortion of ZrO₂. Zr3Ce1p exhibits the largest crystal structure transition, indicating that the low percentage of doped Ce can exert the greatest influence on the ZrO₂ cell structure. Furthermore, thermal reduction can strongly affect the surface of samples and directly raise the O_V concentration. As UV–vis spectra revealed, the synergistic strategy can minimize the bandgap of ZrO₂ (5.03 eV) to 1.87 eV (Zr3Ce1Ca2), showing a 62.8% decrement. Meanwhile, Zr3Ce1Ca2 shows the fastest degradation of methylene blue (24.73%) under light conditions without a sacrificial agent, higher than ZrO₂ by 242%.

Photothermal catalytic CO₂ methanation is a promising strategy, yet its efficiency is hindered by the inherent stability of CO₂ and the rapid recombination of photogenerated charge carriers. Among non-noble metal catalysts, Ni-based catalyst is a promising candidate for CO₂ methanation, with sintering and agglomeration remaining to be addressed. Herein, NiMn/TiO₂ bimetallic catalysts with varying Ni/Mn ratios were synthesized to overcome these issues. Characterization results demonstrate that Mn incorporation enhances CO₂ adsorption capacity by increasing oxygen vacancies and significantly improves the separation efficiency of photogenerated carriers. Furthermore, Mn doping optimizes the electronic structure of the catalyst, narrowing its bandgap for improved light absorption. But the catalytic performance is highly dependent on the Ni/Mn ratio. The synergistic effect of Ni and Mn can be maximized when the Ni/Mn ratio is 1:1, which is specifically manifested as the best catalytic activity. Excessive Mn loading covers active Ni sites and impedes electron transfer, thereby degrading activity.
