Three morphology controllable CeO 2 crystals were successfully synthesized via the thermal decomposition of CeCO 3 OH precursors, which was newly prepared on the basis of a simple and template-free hydrothermal reaction between CeCl 3 solution and a CO 2 -storage material (CO 2 SM). In the formation processes of three CeCO 3 OH precursors, the CO 2 SM could be newly used as raw material and structural director. Meanwhile, the results presented the wider pH values (5.24-8.35) for isoelectric point of CeCO 3 OH precursors. After the CeCO 3 OH precursors were isolated, the filtrate could be recycled to absorb CO 2 again and prepare CeCO 3 OH precursors with two special polymorphs. Three as-prepared CeO 2 crystals by annealing three CeCO 3 OH precursors at 500 8C for 4 h showed the maximum adsorption amounts of 23.5, 18.7 and 20.5 mg/g for 8% CO 2 /N 2 mixture. As a result, this work provided the wider pH values for isoelectric point of CeCO 3 OH precursors and a simple method for the preparation of CeO 2 crystals with a short time and CO 2 adsorption properties.

“…50,51 Due to its wide range of applications, researchers are focusing more on synthesizing CeO 2based materials of controlled size, shape, and morphology as the size, shape, and morphology significantly affect the physicochemical properties and hence their application potential. [52][53][54][55] Accordingly, different chemical approaches such as precipitation, [55][56][57] sol-gel, 48 hydrothermal, 58,59 thermal decompositions, 49 and solution combustion 60 have been extensively used for the synthesis of CeO 2 NPs. However, researchers put more emphasis on the precipitation method because the precipitation approach is the simplest, most environmentally friendly, most cost-effective, and easy to scale up.…”

Bi/CeO2 (BC‐x) photocatalysts are successfully prepared by solvothermal loading Bi nanoparticles and Bi‐doped CeO2 derived by Ce‐MOF (Ce‐BTC). Formaldehyde gas (HCHO) and tetracycline hydrochloride (HTC) are used to evaluate the photocatalytic activity of the synthesized Bi/CeO2. For BC‐1000 photocatalyst, the degradation of HTC by 420 nm < λ < 780 nm light reaches 91.89% for 90 min, and HCHO by 350 nm < λ < 780 nm light reaches 94.66% for 120 min. The photocatalytic cycle experiments prove that BC‐1000 has good cyclic stability and repeatability. The results of photoluminescence spectra, fluorescence lifetime, photocurrent response, and electrochemical impedance spectroscopy showed that the SPR (Surface Plasmon Resonance) effect of Bi nanoparticles acted as a bridge and promoted electron transfer and enhanced the response‐ability of Bi/CeO2 to visible light. Bi‐doping produced more oxygen vacancies to provide adsorption sites for adsorbing oxygen and generated more ·O2− thus promoting photocatalytic reactions. The mechanism of photocatalytic degradation is analyzed in detail utilizing active free radical capture experiments and electron paramagnetic resonance (EPR) characterization. The experimental results indicate that ·O2− and h+ active free radicals significantly promote the degradation of pollutants.
