First I would like to express some doubt about the suitability of the adjective ‘anomalous’, which in the present context can only mean ‘unusual’. Nothing in Nature can be truly anomalous in the broad scheme of things. Furthermore, the programme shows that what we are looking for is indication from known terrestrial biochemistry of directions in which we may find possible extensions to other bio-logical systems of a novel type, even to some in which the role of chemical elements may be modified or more drastically changed. Recent progress in organic chemistry offers many suggestions such as the boron-nitrogen and boron-carbon and phosphorus-nitrogen combinations. Silicon has often been suggested as a basis for life chemistry under non-terrestrial conditions. All these ideas have to be entertained as possibilities, but my own belief is that the carbon-oxygen-nitrogen-hydrogen structures would always be preferred as the basis of life in a range of conditions approximating to those of the Earth. This view is based on the fundamental properties of compounds of these elements and the nature of the chemical links between their atoms. Phosphorus, sulphur and various metals have essential parts to play, mainly in the promotion of biochemical transformations.

Photocatalytic Applications

Hetero-nanomaterials constructed by plasmonic metals and functional semiconductors show enormous potential in photocatalytic applications, such as water splitting, hydrogen production, CO2 reduction, pollutants treatment. Their photocatalytic performances can be better regulated through adjusting structure, ingredient, and components arrangement. Therefore, the reasonable design and synthesis of metal/semiconductor hetero-nanostructures is of vital significance. In this article, we briefly review the recent progress in efficiently establishing metal/semiconductor nanomaterials for improved photocatalysis. The defined photocatalysts mainly include traditional binary hybrids, ternary multi-metals/semiconductor and metal/multi-semiconductors heterojunctions. The underlying physical mechanism for the improved photocatalytic activity of the established photocatalysts are highlighted. At the end of this article, a brief summary and possible future perspectives for further development in this field are demonstrated.

Photocatalytic Applications

In the 21st century, the development of sustainable energy and advanced technologies to cope with energy shortages and environmental pollution has become vital. Semiconductor photocatalysis is a promising technology that can directly convert solar energy to chemical energy and is extensively used for its environmentally-friendly properties. In the field of photocatalysis, graphitic carbon nitride (g-C3N4) has obtained increasing interest due to its unique physicochemical properties. Therefore, numerous researchers have attempted to integrate quantum dots (QDs) with g-C3N4 to optimize the photocatalytic activity. In this review, recent progress in combining g-C3N4 with QDs for synthesizing new photocatalysts was introduced. The methods of QDs/g-C3N4-based photocatalysts synthesis are summarized. Recent studies assessing the application of photocatalytic performance and mechanism of modification of g-C3N4 with carbon quantum dots (CQDs), graphene quantum dots (GQDs), and g-C3N4 QDs are herein discussed. Lastly, challenges and future perspectives of QDs modified g-C3N4-based photocatalysts in photocatalytic applications are discussed. We hope that this review will provide a valuable overview and insight for the promotion of applications of QDs modified g-C3N4 based-photocatalysts.
