Sepiolite/Cu2O/Cu photocatalyst: Preparation and high performance for degradation of organic dye

Preparation of Cu2O@TiOF2/TiO2and its photocatalytic degradation of tetracycline hydrochloride wastewater

“…7, the absorption peaks around 3716 cm À1 and 1614 cm À1 are attributed to the stretching vibration and bending vibration of O-H, and the water molecules absorbed by the catalyst surface. [45][46][47] The appearance of an absorption peak near 2961 cm À1 is caused by a hydrogen bond formed by the intermolecular association of hydroxyl groups. 48 The absorption peaks around 1051 cm À1 and 500 cm À1 are due to the stretching vibration of the Ti-O group.…”

A three-dimensional nano-network WO3/F-TiO2-{001} heterojunction constructed with OH-TiOF2 as the precursor and its efficient degradation of methylene blue

“…7 that the corresponding absorption peaks were generated near 1607 cm À1 and 3388 cm À1 due to the bending vibration and stretching of the water molecules and O-H attached to the surface of the catalyst. [64][65][66] The band at 2300 cm À1 corresponds to the vibration of atmospheric carbon dioxide, 67 and absorption peaks near 584 cm À1 are caused by Ti-O-Ti vibration stretching. 68 The catalyst only produced a slight absorption peak near 912 cm À1 , which was caused by the stretching vibration of the Ti-F bond formed by F-TiO 2 .…”

Supported nanocatalysts: recent developments in microwave synthesis for application in heterogeneous catalysis

“…The solid supports help to maintain the size, shape, morphology of nanocatalysts and also limit the leaching of metal ions favorable for achieving durable and enhanced catalytic performance. The solid supports used prominently include graphene, 11,12 Zeolite, 13 Cellulose, [14][15][16] activated coke/carbon, 17,18 Sepiolite, 19 bentonite, 20 SiO 2 , 21,22 Al 2 O 3 23,24 etc. In general, the preparation of supported nanocatalysts is usually followed in two steps.…”
