Effect of layers on the photocatalytic hydrogen evolution in Dion–Jacobson layered-tantalum perovskites

Abstract

Tantalum-based layered perovskites have always been an interesting topic in photocatalysis, but limited information has been reported in terms of its layer factor. In this work, we have synthesized Dion-Jacobson...

Local structure analysis and structure mining for design of photocatalytic metal oxychloride intergrowths

“…Even though the chemical properties of two-layer KLaTa 2 O 7 and three-layer KCa 2 Ta 3 O 10 were similar, the photocatalytic activity of KLaTa 2 O 7 was found to be two times higher than that of KCa 2 Ta 3 O 10 . 39 Also, Sillén–Aurivillius layered oxyhalides with single-, double- and triple-perovskite slabs were found to be promising visible-light-driven photocatalysts for water splitting, with different behaviors observed depending on the number of perovskite blocks. 15 Altering the stacking in these oxyhalide systems causes changes in the internal electric field, leading to modulation of charge carrier migration.…”

Cost-effective preparation of layered tantalum oxynitrides for visible light-driven photocatalysis

“…The working electrodes were prepared via a spin-on-conductive glass process, as previously reported. 17 Firstly, 10 mg of catalyst powder was added to the prepared 5% PVDF/NMP solvent. Then, the mixture was ground to form a uniform viscous liquid and evenly smeared on a conductive glass substrate (fluorine-doped tin oxide, FTO).…”

“…S6 †), which is consistent with our previous report. 17 In contrast, nitrogen doping caused the color of the products to change. With an increase in the reaction temperature, the color of the nitrided products changed from light-yellow to red-brown.…”

“…In the literature, the effect of the number of layers in these two layered oxides on their photocatalytic performances was previously investigated. 17 Subsequently, studies on layered oxides were expanded to layered oxynitrides. 18,19 The reported oxynitrides 18,19 can be compared with our work in terms of their photocatalytic properties and synthetic methods.…”

Molecular engineering for constructing a D–A system and enhancing delocalization in g-C3N4 with superior photocatalytic activity

“…1,2 Photocatalysis, as an environmental-friendly technology, can sustainably convert inexhaustible solar energy into storable chemical fuels. [3][4][5][6][7] At present, photocatalysis for water splitting, degradation of organic pollutants, nitrogen xation, and CO 2 reduction have attracted considerable interest. [8][9][10][11][12][13] As we all know, photocatalysts play decisive roles in photocatalytic reactions, which regulate solar power harvesting efficiency.…”
