Enhanced photocatalytic degradation of indoor formaldehyde by sepiolite decorated with TiO2 nanoparticles: Effects of key preparation parameters

Cerium-Doped TiO2 and Sepiolite Nanocomposites for Tetracycline Inactivation in Water Treatment

“…Furthermore, the researchers found data similar to this work in which there was a decrease in the surface area of the clay when the oxide was inserted . Junying et al , 2023, also observed a decrease in the surface area of the samples when they synthesized TiO 2 with Sepiolite in different percentages of oxide mass . Similar results have already been reported in other studies. , …”

“…In the image of the TiO 2 –Sep sample in Figure S2 (a), the fibrous morphology of the Sepiolite is observable, a distinctive characteristic of this material. Clusters and interlaced structures, resembling needles or rods with varied dimensions, are notable in previous studies. , …”

“…Heterogeneous photocatalysis technology is an advanced oxidation process (AOP) for effluent treatment and has been recognized as a green and effective technology for converting organic pollutants into CO 2 and H 2 O . In heterogeneous photocatalysis, light absorption by a photocatalyst creates an electron–hole ( e – / h + ) pair, which reacts with water and oxygen to generate reactive radicals that can degrade organic pollutants into harmless substances such as water and carbon dioxide.…”

Sepiolite-Supported Manganese Oxide as an Efficient Catalyst for Formaldehyde Oxidation: Performance and Mechanism

“…Sepiolite’s unique structure accounts for its homogeneous pore size, elevated porosity, large surface area, and profusion of silanol groups [ 36 , 37 , 38 , 39 ]. Although there have been reports of sepiolite in HCHO degradation, most of them have focused on photocatalysis [ 40 , 41 , 42 ], with thermocatalysis receiving even fewer reports [ 20 , 34 ]. Our research on HCHO oxidation via the use of sepiolite and silver has shown that the catalysts have unique adsorption characteristics and are capable of fully decomposing HCHO at 52 °C into CO 2 and H 2 O [ 43 ].…”
