“…Indeed, although the bare WO 3 showed a small bandgap (2.61 eV), its photoactivity was not high. As reported in the literature, [58,59] the high recombination rate between the holes and the electrons generated during the irradiation of WO 3 caused a poor photoactivity, confirming its positive effects mainly if it is used as promoter or as co‐catalyst instead of principal component of mixed oxides or composites [58–61] …”

“…[8] Indeed, although the bare WO 3 showed a small bandgap (2.61 eV), its photoactivity was not high.

[58][59][60][61] The promising performance of the La-1 %WO 3 catalyst can be a starting point to design efficient photocatalytic composite systems, where the sorption capability of the main material component is exploited, and its photocatalytic features are enhanced by the addition of a co-catalyst.…”

La 2 O 2 CO 3 -WO 3 composites were here proposed as unconventional photocatalysts for the removal of phthalates in water. The high sorption properties of the lanthanum dioxide carbonate allowed a strong adsorption of the phthalates which facilitated the following solar photocatalytic degradation, further boosted by the addition of small amounts of WO 3 (1 wt %). On the contrary, a higher content of WO 3 had a detrimental effect due to the covering of the surface sites of La 2 O 2 CO 3 that inhibited the adsorption process. This double mechanism of strong adsorption-photocatalytic oxidation led, after 6 h of solar irradiation, to 67 % and 63 % dimethyl phthalate and di(2ethylhexyl)phthalate degradation, respectively. The phthalates were degraded to less persistent pollutants that, however, were completely removed after 9 h of irradiation. The La 2 O 2 CO 3 -WO 3 system appears promising for its application in the removal of the emerging contaminants from water.[a] E.

“…These physical and chemical properties are often closely related to the morphologies, surface states, and interfacial properties of catalysts, which can be obtained from their material synthesis. 77 At present, there are many methods for synthesizing CoFe 2 O 4 , and different preparation techniques and synthesis conditions will affect its basic properties and catalytic activity. Commonly used methods for synthesizing CoFe 2 O 4 mainly include the sol-gel method, hydrothermal method, and co-precipitation method.…”
