UV-Enhanced Formaldehyde Sensor Using Hollow In2O3@TiO2 Double-Layer Nanospheres at Room Temperature

“…As shown in Figure c, the bands appearing at 2999, 2838, 1421, and 1356 cm –1 are assigned to the absorption vibration peaks of formate . Among them, at 2999 and 2838 cm –1 are the C–H stretching vibration absorption peaks ν­(C–H) of formate, at 1421 cm –1 is the C–H bending vibration absorption peak δ­(C–H) of formate, and at 1356 cm –1 is the COO symmetric stretching vibration absorption peak ν­(COO).…”

Modular preparation of functional bimetallic spinels from metal–organic frameworks: a deep exploration from macro and micro perspectives

“…187 Therefore, exploring such materials has the potential to facilitate the future development of MOF-derived bimetallic spinels for NO x degradation. In addition, the application scope of derived materials in inorganic pollutants is currently limited to NO x and formaldehyde, 99 so it is necessary to explore the degradation process of more inorganic gaseous pollutants.…”

“…6). 98,99 To date, few studies have specically summarized these variations. Therefore, the variations caused by MOFs for derived bimetallic spinels (structural changes, property advantages, and vacancy defects) are elucidated in detail in this chapter, which are important for an in-depth exploration of these materials.…”

Bimetallic oxide Cu2O@MnO2 with exposed phase interfaces for dual-effect purification of indoor formaldehyde and pathogenic bacteria

“…In order to solve the problem of catalyst inactivation at room temperature, many reported studies have attempted to modify the original MnO 2 catalyst to improve its ability to activate O 2 and H 2 O molecules into reactive oxygen species (O* and $OH), promoting the decomposition of intermediates during catalysis. [12][13][14] In particular, by combining with transition metal oxide photocatalysts, the modied MnO 2 catalyst could generate more reactive oxygen species under the action of excited carrier transitions and the interface effect of bimetallic oxides, which is regarded as a feasible strategy to improve the activity and stability of an MnO 2 -based catalyst for catalytic HCHO oxidation at room temperature. 15,16 Cuprous oxide (Cu 2 O), as a P-type Cu-based semiconductor photocatalyst with a forbidden bandwidth of 2.17 eV, has recently begun to be applied in the eld of environmental purication.…”
