Carbon dioxide photocatalytic reduction (CO2-PR) is an efficient method for controlling CO2emissions and generating cleaner energy while mitigating global warming. Tungsten oxides (WxOy) have attracted considerable attention for CO2-PR due to their excellent spectral absorbance. However, comprehensive reviews are lacking on the use of WxOyfor CO2-PR. Therefore, this review provides a detailed summary of t research progress made with WxOy-based catalysts in CO2-PR. It also explains the fundamental principles of CO2-PR and evaluates key performance indicators that affect the activity of WxOy-based photocatalysts,including yield, selectivity, stability, and apparent quantum yield. Additionally, this review explores opportunities for synthesizing high-performance WxOy-based photocatalysts and highlights their potential for the green preparation of C1/C2 products through CO2-PR. These innovative strategies aim to address the challenges and pressures associated with energy and environmental issues, particularly by enhancing artificial photosynthesis efficiency.

Emerging contaminants (ECs) are widely present in aquatic environments, posing potential risks to both ecosystems and human health. Theultrasound-assisted persulfate oxidation process has attracted considerable attention in the degradation of ECs due to its ability to generate bothsulfate radicals and cavitation effects, enhancing degradation effects. In this paper, the principle of ultrasonic synergistic Fenton-like oxidationsystem for degrading organic pollutants was reviewed, divided into homogeneous system, non-homogeneous system, and single-atom system toexplore the synergistic effect of ultrasound-enhanced persulfate technology in three aspects, and the effects of environmental factors such asultrasonic frequency and power, system pH, temperature, and initial oxidant concentration on the system's decontamination performance werediscussed. Finally, future research on ultrasonically activated persulfate technology is summarized and prospected.

A Cu–Fe–La/γ-Al_2O_3(CFLA) catalyst was prepared by the excessive impregnation method and characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. The results indicate that the catalyst contained mostly Cu^(2+), Fe^(3+), and La^(3+)and a small amount of Cu^+, Fe^(2+), and La. The active components were uniformly distributed in the catalyst, and the particle size of the components was approximately 7.5 nm. The CFLA catalyst was used for the treatment of methyl orange(MO) solution by catalytic wet air oxidation(CWAO), and it exhibited a high catalytic activity. The catalytic reaction involved variable valence states of metals and free-radical reaction mechanism. The CWAO reaction of MO solution was fitted by a segmented first-order dynamic model, and the rapid reaction apparent activation energy was 13.9 k J·mol^(-1).
