Special Issue Information

Dear Colleagues,

The aim of this Special Issue is to deliver recent research progress in the field of photoactive nanomaterials to the scientific community. This Special Issue focuses on photoactive nanomaterials from fundamental research to their applications. Included are the fundamental study of photoactive nanomaterials in solar energy conversion starting with light harnessing, charge separation/recombination, and catalytic reaction kinetics, as well as their various applications including energy, environmental, and catalytic. Applications in the energy field include photovoltaic use, as well as fuel generation from watersplitting, biomass, carbon dioxide, nitrogen conversion, etc. Environmental applications include photo degradation of organic and inorganic pollutants. Some examples of catalytic applications include photocatalytic conversion of biomass-derived platform molecules, carbon dioxide, and nitrogen. The application of the photoactive nanomaterials is not limited to the above three fields. The fundamental study of photoactive nanomaterials can experimental and theoretical investigations of solar energy conversion, including photovoltaic and photocatalytic mechanisms using different simulation software from material design to reaction kinetics. The scope of this Special Issue can have photoactive nanomaterial synthesis, a basic study of the solar energy conversion process with simulations, and applications including environmental, catalytic, photovoltaic, and solar fuel generation. Other research areas of photoactive nanomaterials are also welcomed. Manuscripts can be review, research and communications.

Perovskite solar cells (PSCs) with a standard sandwich structure suffer from optical transmission losses due to the substrate and its active layers. Developing strategies for compensating for the losses in light harvesting is of significant importance to achieving a further enhancement in device efficiencies. In this work, the down-conversion effect of carbon quantum dots (CQDs) was employed to convert the UV fraction of the incident light into visible light. For this, thin films of poly(methyl methacrylate) with embedded carbon quantum dots ([email protected]) were deposited on the illumination side of PSCs. Analysis of the device performances before and after application of [email protected] photoactive functional film on PSCs revealed that the devices with the coating showed an improved photocurrent and fill factor, resulting in higher device efficiency.

Due to the capability of utilizing light energy to drive chemical reactions, photocatalysis has been widely accepted as a green technology to help us address the increasingly severe environment and energy issues facing human society. To date, a large amount of research has been devoted to enhancing the properties of photocatalysts. As reported, coupling semiconductors with metals is one of the most effective methods to achieve high-performance photocatalysts. The excellent properties of metal/semiconductor (M/S) nanocomposite photocatalysts originate in two aspects: (a) improved charge separation at the metal-semiconductor interface; and (b) increased absorption of visible light due to the surface plasmon resonance of metals. So far, many M/S nanocomposite photocatalysts with different structures have been developed for the application in environmental remediation, selective organic transformation, hydrogen evolution, and disinfection. Herein, we will give a review on the M/S nanocomposite photocatalysts, regarding their fundamentals, structures (as well as their typical synthetic approaches), applications and properties. Finally, we will also present our perspective on the future development of M/S nanocomposite photocatalysts. Full article

Title: White Light emission by one pot encapsulation of commercial dyes into small pore-size aluminophosphate

Abstract: By the simultaneous combination of rationally chosen dyes, emitting in the blue, green and red region of the electromagnetic spectrum, into the narrow channels of the AEL-zeolitic type structure MgAPO-11, a solid-state system with efficient white light emission under UV excitation is achieved. The dyes herein selected are acridine (AC), pyronin Y (PY) and LDS 722, combination that allows a white fluorescence by means of a partial FRET energy transfer between them. A straightforward synthesis through the one-pot occlusion of the chromophores, after the optimization of the initial dye proportion in the synthesis gel, is proposed to attain a resultant hybrid system with high quality white light emission.
