英文摘要	Photocatalysis has proven to be a green technology that possesses the synergy between addressing climate change and combating air pollution. Compared with traditional photocatalysts, Cerium oxide (CeO 2 ) holds distinct advantages such as low-cost, and high affinity for Ce 3 + /Ce 4 + redox pair. This study presents a systematic investigation into the modification of CeO 2 morphologies via optimized one-step hydrothermal synthesis method with low-temperature control. The findings reveal that CeO 2 nanorods exhibited the notable photocatalytic performance, achieving 71.8% NO degradation while generating a mere 4.1% of toxic byproducts. Additionally, the promising CO and CH 4 yields from CO 2 conversion were 4.11 and 3.67 mu mol g -1 h -1 , respectively. The improvement in photocatalytic activity is attributed to the relationship between the specific surface area and the defects within the CeO 2 nanorods structure. Furthermore, CeO 2 nanorods also emerged as promising candidates for superior and sustainable photocatalytic CO 2 conversion, demonstrating high stability, with only 0.7% and 1.1% reduction in CO and CH 4 yields after four successive photocatalytic cycles. This study underscores the potential of CeO 2 nanorods in advancing green technologies for clean energy and contributes valuable insights to the field of practical zero emissions strategies.
