Recent advances in spinel ferrite-based magnetic photocatalysts for efficient degradation of organic pollutants

Water Science and Technology, 2023
Although spinel ferrite (MFe2O4, M = Zn, Ni, Mn, etc.) has been reported as a promising catalyst, its low photocatalytic activity under visible light greatly restricts its practical application.

Photocatalytic activity of kaolinite

Catalysis Communications, 2011
Abstract The photocatalytic activity of commercial kaolinite (KGa-1b) was evaluated for the degradation of methylene blue (MB) in aqueous suspension and of toluene in the gas phase. An enhanced photolysis of MB in the presence of kaolinite was detected, albeit at a slower rate than in the presence of the same mass of commercial TiO 2 P25.

Precursor-Dependent Photocatalytic Activity of Carbon Dots [PDF]

Molecules, 2019
This work systematically compares both structural features and photocatalytic performance of a series of graphitic and amorphous carbon dots (CDs) prepared in a bottom-up manner from fructose, glucose, and citric acid. We demonstrate that the carbon source and synthetic procedures diversely affect the structural and optical properties of the CDs, which

Enhanced photocatalytic activity and cycle stability driven by ultrasonic vibration for ferroelectric photocatalysts

IET Nanodielectrics, 2019
Ferroelectric materials have been applied in the photocatalytic field due to the internal electric field generated by the spontaneous polarisation. In this study, it is found that the ferroelectric BaTiO(3) catalysts exhibit the excellent photocatalytic ...

A simple strategy to simultaneously improve the lifetime and activity of classical iridium complex for photocatalytic water‐splitting

Aggregate, 2023
Herein, we design and synthesize a series of oligomers [Ir(ppy)2(dabpy)‐ODPA]n (D1‐n) by copolymerization of [Ir(ppy)2(dabpy)][PF6] (D2) with 4,4′‐Oxydiphthalic anhydride (ODPA), to resolve the problem of simultaneous improvement of stability and ...
