Special Issue Information

Dear Colleagues,

Sunlight is a naturally available, non-polluting, and limitless source of renewable energy, which can be stored chemically, or utilized in carrying out 'green' chemical synthesis. Unlike conventional thermal or nuclear energy production, light does never introduce any byproducts or toxic wastes. Solar energy appears as one of the most intriguing sources of energy, where nature is utilizing it from the very beginning in the photosynthesis process. The photocatalysis begins with titanium dioxide in human civilization, but the history of TiO2 is linked with ancient times, as this white pigment is chemically stable, inexpensive, and harmless. It draws special attention to science in the early part of the 20th century. In 1938, TiO2 was used in photobleaching for dyes. Later, while Akira Fujishima was working under Professor Kenichi Honda as a Ph.D. student at Tokyo University in 1967, they discovered the photocatalytic decomposition of water by exposing the TiO2 electrode under a strong light. Thereafter the scientists from different fields came and diversified the Photocatalysts for various applications. The materials like quantum dots, metal-organic frameworks, composite materials, organic molecules, or metal complexes are used in water splitting, CO2 reduction, decomposition of organic pollutants, organic synthesis, etc. In this emerging area, computational modeling is becoming an indispensable part of the catalyst designing strategy, before preparing them chemically in a wet laboratory.

To bring some of the exciting recent works on green photocatalysts, this special issue on ‘Green Photocatalysts for Energy and Environmental Process’ is opened for all contributors of the photocatalysis for renewable energy storage, photodegradation of pollutants, and photosynthesis fields. We also inspire the authors to emphasize the designing strategy of catalysts for motivating the young researchers as well. Here we invite authors to submit novel and original works to this special issue which could accumulatively extend and advance our scientific understanding. This issue will emphasize the following areas mentioned as keywords, but could even be diversified further.  ​

Before submission authors are requested to read carefully the journal’s guidelines for authors. Review papers can only be submitted by editorial invitation. Please note that the papers that match with the scope of this Special Issue will only be considered.

In the coming years, multipurpose catalysts for delivering different products under the same chemical condition will be required for developing smart devices for industrial or household use. In order to design such multipurpose devices with two or more specific roles, we need to incorporate a few independent but externally controllable catalytically active centers. Through space crystal engineering, such an externally controllable multipurpose MOF-based photocatalyst could be designed. In a chemical system, a few mutually independent secondary reaction cycles nested within the principal reaction cycle can be activated externally to yield different competitive products. Each reaction cycle can be converted into a time crystal, where the time consuming each reaction step could be converted as an event and all the reaction steps or events could be connected by a circle to build a time crystal. For fractal reaction cycles, a time polycrystal can be generated. By activating a certain fractal event based nested time crystal branch, we can select one of the desired competitive products according to our needs. This viewpoint intends to bring together the ideas of (spatial) crystal engineering and time crystal engineering in order to make use of the time–space arrangement in reaction–catalysis systems and introduce new aspects to futuristic chemical engineering technology.
