Advancement of renewable energy technologies via artificial and microalgae photosynthesis.

There has been an urgent need to tackle global climate change and replace conventional fuels with alternatives from sustainable sources. This has led to the emergence of bioenergy sources like biofuels and biohydrogen extracted from microalgae biomass. Microalgae takes up carbon dioxide and absorbs sunlight, as part of its photosynthesis process, for growth and producing useful compounds for renewable energy.

Synergistic effects of the hybridization between boron-doped carbon quantum dots and n/n-type g-CN homojunction for boosted visible-light photocatalytic activity.

Dye wastewater has raised a prevalent environmental concern due to its ability to prevent the penetration of sunlight through water, thereby causing a disruption to the aquatic ecosystem. Carbon quantum dots (CQDs) are particularly sought after for their highly tailorable photoelectrochemical and optical properties. Simultaneously, graphitic carbon nitride (g-CN) has gained widespread attention due to its suitable band gap energy as well as excellent chemical and thermal stabilities.

Metal-free n/n-junctioned graphitic carbon nitride (g-CN): a study to elucidate its charge transfer mechanism and application for environmental remediation.

Graphitic carbon nitride (g-CN) has been regarded as a promising visible light-driven photocatalyst ascribable to its tailorable structures, thermal stability and chemical inertness. Enhanced photocatalytic activity is achievable by the construction of homojunction nanocomposites to reduce the undesired recombination of photogenerated charge carriers. In the present work, a novel g-CN/g-CN metal-free homojunction photocatalyst was synthesized via hydrothermal polymerization.
