Abstract:
The novel magnetically retrievable Bi2WO6/MCNOs (MCNOs, magnetic carbon nano-onions) composite was synthesized via a simple hydrothermal method. The characteristics of the as-prepared materials were explored by XRD, Raman, SEM, TEM, XPS, UV-vis DRS, N2 adsorption-desorption techniques and FT-IR techniques, and the paramagnetic nature of the as-prepared composite was determined by hysteresis loops measurements. In this work, rhodamine B (RhB), methyl orange (MO), methylene blue (MB), tetracycline (TC) and p-nitrophenol (PNP) were chosen as the typical organic pollutants to evaluate the photodegradation efficiency of the as-prepared composite. The results indicated that Bi2WO6/MCNOs have a superior performance on photocatalytic activity than pure Bi2WO6. Furthermore, a possible mechanism was proposed based on the physic-chemical and photocatalytic properties. This work will provide new methodology for designing next generation photocatalyst for environmental purification.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

Classifying Matter by Composition
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...
