Monolithic metal-containing TiO2 aerogels assembled from crystalline pre-formed nanoparticles as efficient photocatalysts for H2 generation

Co/Ni-polyoxotungstate photocatalysts as precursor materials for electrocatalytic water oxidation

“…32 performance of oxide WOCs. These ndings show that synthetic methods and underlying mechanisms 36 are an important step in WOC optimization, [37][38][39] and that a certain extent of preorganization of the metal centers in the precursor is benecial for higher catalytic activity. 40 To this end, we systematically explored synthesis-activity relationships with a series of studies on spinel-type Co 3 O 4 catalysts, starting with in situ PXRD monitoring of temperature-dependent hydrothermal Co 3 O 4 formation mechanisms.…”

Emerging Concepts in Carbon Nitride Organic Photocatalysis

“…[16] Processability of semiconductors alongside insolubility within common solvents make them extremely useful for the fabrication of nano-, micro-and macro-structures with applications in photocatalysis as coatings in microfluidic reactors, [17] active layers in photoelectrocatalysis, [18] photocatalytically active monoliths [19] and aerogels. [20] Based on elemental composition, semiconductor materials can be divided into several classes: inorganic materials, represented by metal oxides and chalcogenides, [21] as well as perovskites, [22] metal organic frameworks, composed of metal linker and organic ligand, [23,24,25,26] and organic materials, built exclusively from organogenic elements.…”

“…Higher thermal and chemical stability, ease of recovery from the reaction mixture, and recyclability make semiconductor materials more attractive in comparison to molecular systems [16] . Processability of semiconductors alongside insolubility within common solvents make them extremely useful for the fabrication of nano‐, micro‐ and macro‐structures with applications in photocatalysis as coatings in microfluidic reactors, [17] active layers in photoelectrocatalysis, [18] photocatalytically active monoliths [19] and aerogels [20] …”

Fast Microwave Synthesis of Gold-Doped TiO2 Assisted by Modified Cyclodextrins for Photocatalytic Degradation of Dye and Hydrogen Production

“…In fact, we can suppose that the residual organic compounds decrease the contact between the semi-conductor and the gold and so reduce the electron transfer. Furthermore, the CDs residues could maybe mask some of the active sites of the semi-conductor or reduce the potential adsorption of the MO [43].…”
